Abstract

In their comment (1), Hawreliak et al. claims that our observation of stacking fault formation and transonic dislocation propagation in diamond (2) is not valid as they interpret the observed features as cracks. In this response letter, we describe our rationale for interpreting the observed features as stacking faults. We also address other points raised in their comments, including the clarifications of how the results of Makarov et al. (3) are not in conflict with our study., Comment: Comment on arXiv:2401.04213. 10 pages, 2 figures

Abstract

Sub-picosecond optical laser processing of metals is actively utilized for modification of a heated surface layer. But for deeper modification of different materials a laser in the hard x-ray range is required. Here, we demonstrate that a single 9-keV x-ray pulse from a free-electron laser can form a um-diameter cylindrical cavity with length of ~1 mm in LiF surrounded by shock-transformed material. The plasma-generated shock wave with TPa-level pressure results in damage, melting and polymorphic transformations of any material, including transparent and non-transparent to conventional optical lasers. Moreover, cylindrical shocks can be utilized to obtain a considerable amount of exotic high-pressure polymorphs. Pressure wave propagation in LiF, radial material flow, formation of cracks and voids are analyzed via continuum and atomistic simulations revealing a sequence of processes leading to the final structure with the long cavity. Similar results can be produced with semiconductors and ceramics, which opens a new pathway for development of laser material processing with hard x-ray pulses.

Abstract

We present measurements on Fe$_2$O$_3$ amorphization and melt under laser-driven shock compression up to 209(10) GPa via time-resolved in situ x-ray diffraction. At 122(3) GPa, a diffuse signal is observed indicating the presence of a non-crystalline phase. Structure factors have been extracted up to 182(6) GPa showing the presence of two well-defined peaks. A rapid change in the intensity ratio of the two peaks is identified between 145(10) and 151(10) GPa, indicative of a phase change. Present DFT+$U$ calculations of temperatures along Fe$_2$O$_3$ Hugoniot are in agreement with SESAME 7440 and indicate relatively low temperatures, below 2000 K, up to 150 GPa. The non-crystalline diffuse scattering is thus consistent with the - as yet unreported - shock amorphization of Fe$_2$O$_3$ between 122(3) and 145(10) GPa, followed by an amorphous-to-liquid transition above 151(10) GPa. Upon release, a non-crystalline phase is observed alongside crystalline $\alpha$-Fe$_2$O$_3$. The extracted structure factor and pair distribution function of this release phase resemble those reported for Fe$_2$O$_3$ melt at ambient pressure., Comment: 11 pages, 4 figures, under review

Abstract

The motion of line defects (dislocations) has been studied for over 60 years but the maximum speed at which they can move is unresolved. Recent models and atomistic simulations predict the existence of a limiting velocity of dislocation motions between the transonic and subsonic ranges at which the self-energy of dislocation diverges, though they do not deny the possibility of the transonic dislocations. We use femtosecond x-ray radiography to track ultrafast dislocation motion in shock-compressed single-crystal diamond. By visualizing stacking faults extending faster than the slowest sound wave speed of diamond, we show the evidence of partial dislocations at their leading edge moving transonically. Understanding the upper limit of dislocation mobility in crystals is essential to accurately model, predict, and control the mechanical properties of materials under extreme conditions.

Abstract

Broadening of hydrogenic spectral lines is an important tool in spectroscopic diagnostics of various laboratory and astrophysical plasmas. We review recent analytical advances in three areas. First, we review the analytical solution for the splitting of hydrogenic lines under the combination of a circularly polarized electromagnetic wave with a strong magnetic field. Practical applications of this solution relate to the spectroscopic diagnostic of the electron cyclotron waves and to the relativistic laser–plasma interactions. Second, we review analytical results concerning the Stark–Zeeman broadening of the Lyman-alpha (Ly-alpha) line in plasmas. These results allow for the Stark width of the Ly-alpha π-component to be used for the experimental determination of the ion density or of the root-mean-square field of a low-frequency electrostatic plasma turbulence in the situation where the Zeeman effect dominates over the Stark effects. Third, we review recent analytical advances in the area of the intra-Stark spectroscopy: three different new methods, based on the emergent phenomenon of the Langmuir-wave-caused structures (“L-dips”) in the line profiles, for measuring super-strong magnetic fields of the GigaGauss range developing during relativistic laser–plasma interactions. We also review the rich physics behind the L-dips phenomenon – because there was a confusion in the literature in this regard.

Abstract

Laser-produced plasmas are bright, short sources of X-rays often used for time-resolved imaging and spectroscopy. Absolute measurement requires accurate knowledge of laser-to-x-ray conversion efficiencies, spectrum, photon yield and angular distribution. Here we report on soft X-ray emission from a thin Si foil irradiated by a sub-PW picosecond laser pulse. These absolute measurements cover a continuous and broad spectral range that extends from 4.75 to 7.5 Angstroms (1.7-2.6 keV). The X-ray spectrum consists of spectral line transitions from highly charged ions and broadband emission with contributions from recombination, and free-free processes that occur as electrons decelerate in plasma electromagnetic fields. These quantitative measurements are compared to particle-in-cell simulations allowing us to distinguish bremsstrahlung and synchrotron contributions to the free-free emission. We found that experiment and simulation estimations of laser-to-bremsstrahlung conversion efficiency are in a good agreement. This agreement illustrates the accuracy of experiment and physical interpretation of the measurements.

Abstract

The generation of a plasma with an ultrahigh energy density of 1.2 GJ/cm3 (which corresponds to about 12 Gbar pressure) is investigated by irradiating thin stainless-steel foils with high-contrast femtosecond laser pulses with relativistic intensities of up to 1022 W/cm2. The plasma parameters are determined by X-ray spectroscopy. The results show that most of the laser energy is absorbed by the plasma at solid density, indicating that no pre-plasma is generated in the current experimental setup. [ABSTRACT FROM AUTHOR]

Abstract

The measurement of properties of exotic nuclei, essential for fundamental nuclear physics, now confronts a formidable challenge for contemporary radiofrequency accelerator technology. A promising option can be found in the combination of state-of-the-art high-intensity short pulse laser system and nuclear measurement techniques. We propose a novel Laser-driven Exotic Nuclei extraction-acceleration method (LENex): a femtosecond petawatt laser, irradiating a target bombarded by an external ion beam, extracts from the target and accelerates to few GeV highly-charged nuclear reaction products. Here a proof-of-principle experiment of LENex is presented: a few hundred-terawatt laser focused onto an aluminum foil, with a small amount of iron simulating nuclear reaction products, extracts almost fully stripped iron nuclei and accelerate them up to 0.9 GeV. Our experiments and numerical simulations show that short-lived, heavy exotic nuclei, with a much larger charge-to-mass ratio than in conventional technology, can be obtained in the form of an energetic, low-emittance, high-current beam., Comment: including supplementary information

Abstract

X-ray devices are far superior to optical ones for providing nanometre spatial and attosecond temporal resolutions. Such resolution is indispensable in biology, medicine, physics, material sciences, and their applications. A bright ultrafast coherent X-ray source is highly desirable, for example, for the diffractive imaging of individual large molecules, viruses, or cells. Here we demonstrate experimentally a new compact X-ray source involving high-order harmonics produced by a relativistic-irradiance femtosecond laser in a gas target. In our first implementation using a 9 Terawatt laser, coherent soft X-rays are emitted with a comb-like spectrum reaching the 'water window' range. The generation mechanism is robust being based on phenomena inherent in relativistic laser plasmas: self-focusing, nonlinear wave generation accompanied by electron density singularities, and collective radiation by a compact electric charge. The formation of singularities (electron density spikes) is described by the elegant mathematical catastrophe theory, which explains sudden changes in various complex systems, from physics to social sciences. The new X-ray source has advantageous scalings, as the maximum harmonic order is proportional to the cube of the laser amplitude enhanced by relativistic self-focusing in plasma. This allows straightforward extension of the coherent X-ray generation to the keV and tens of keV spectral regions. The implemented X-ray source is remarkably easily accessible: the requirements for the laser can be met in a university-scale laboratory, the gas jet is a replenishable debris-free target, and the harmonics emanate directly from the gas jet without additional devices. Our results open the way to a compact coherent ultrashort brilliant X-ray source with single shot and high-repetition rate capabilities, suitable for numerous applications and diagnostics in many research fields.

Abstract

The application of fluorescent crystal media in wide-range X-ray detectors provides an opportunity to directly image the spatial distribution of ultra-intense X-ray beams including investigation of the focal spot of free-electron lasers. Here the capabilities of the micro- and nano-focusing X-ray refractive optics available at the High Energy Density instrument of the European XFEL are reported, as measured in situ by means of a LiF fluorescent detector placed into and around the beam caustic. The intensity distribution of the beam focused down to several hundred nanometers was imaged at 9 keV photon energy. A deviation from the parabolic surface in a stack of nanofocusing Be compound refractive lenses (CRLs) was found to affect the resulting intensity distribution within the beam. Comparison of experimental patterns in the far field with patterns calculated for different CRL lens imperfections allowed the overall inhomogeneity in the CRL stack to be estimated. The precise determination of the focal spot size and shape on a sub-micrometer level is essential for a number of high energy density studies requiring either a pin-size backlighting spot or extreme intensities for X-ray heating.

Abstract

高エネルギー/高強度レーザーとプラズマの相互作用の理解はHigh Energy Density Physicsにおける重要な課題である。特にレーザーを固体へ照射する場合、固体表面においては、プラズマ加熱、プラズマ振動、界面不安定性、粒子加速、電磁場生成、といった多彩な物理が発現する。これらの詳細な実験的研究は、計測手法の時間/空間的な分解能によって制限されていた。X-ray Free-Electron Laser(XFEL)の登場により、高輝度な短パルスのX線源が利用できるようになったことで、これらの問題に突破口が開かれ、単発現象であるレーザープラズマ実験においても、高精度な計測が可能になった。 我々は、固体界面におけるプラズマ超高速ダイナミクスを調べるために、日本が誇るXFELのSACLAを用いたポンプ・プローブ実験を実施した。ポンプ光としては500TW高強度短パルスレーザー、ターゲットとしてはメゾスケールロッド集合体（直径500nm、間隔1000nm、長さ13μm、シリコン基板上で規則的配列30×15）、計測手法はメゾスケールに対応するためX線小角散乱を用いた。本来、小角散乱に おいて高強度な原点信号に対してその外側に現れる微弱な散乱光を計測するために ビームストップが使用される。今回はプラズマ化することでロッド群が作る回折パターンの時間発展をより長く（原点周りの低次の信号）追うために、散乱信号が低次から高次までX線CCDカメラのダイナミックレンジに収まるように調整した。具体的には、低次が厚くなるようにアルミ板を積層したステップ式アテニュエーターをビームストップの代用とし、原点を含めた全ての散乱パターンを計測した。, 第62回高圧討論会

Abstract

Meteorites from interplanetary space often include high-pressure polymorphs of their constituent minerals, which provide records of past hypervelocity collisions. These collisions were expected to occur between kilometre-sized asteroids, generating transient high-pressure states lasting for several seconds to facilitate mineral transformations across the relevant phase boundaries. However, their mechanisms in such a short timescale were never experimentally evaluated and remained speculative. Here, we show a nanosecond transformation mechanism yielding ringwoodite, which is the most typical high-pressure mineral in meteorites. An olivine crystal was shock-compressed by a focused high-power laser pulse, and the transformation was time-resolved by femtosecond diffractometry using an X-ray free electron laser. Our results show the formation of ringwoodite through a faster, diffusionless process, suggesting that ringwoodite can form from collisions between much smaller bodies, such as metre to submetre-sized asteroids, at common relative velocities. Even nominally unshocked meteorites could therefore contain signatures of high-pressure states from past collisions.

Abstract

We demonstrate in-line phase-contrast imaging of nanothickness foils by using a relatively large, polychromatic, debris-free femtosecond-laser-driven cluster-based plasma soft x-ray source, and a high-resolution, large dynamic range LiF crystal detector. The spatial coherence length of radiation in our setup reached a value of 5 [micro]m on the sample plane, which is enough to observe phase-contrast enhancement in the images registered by the detector placed only a few hundred micrometers behind the object. We have developed a tabletop soft x-ray emission source, which emits radiation within a 4[pi] sr solid angle, and which allows one to obtain contact and propagation-based phase-contrast imaging ofnanostructures with 700 nm spatial resolutions. This advance could be of utility for metrology applications. OCIS codes: 110.7440, 180.0180, 230.6080, 260.6048.

Abstract

サブ µmオーダの微細構造を有するターゲットに集光強度が相対論領域の高強度レーザーを照射すると、kTオーダの準定常的な磁場などを伴う高エネルギー密度プラズマが生成され、多彩な現象を創出することがシミュレーション研究で示されている。本研究では、これを検証するため、直径が µm、高さが数10 mオーダのシリコンによるロッドを基盤上に mオーダの間隔で配置した集合体をターゲットとして、これに集光強度が10^19-21 W/cm^2, パルス長が30~50 fsecのレーザー（京大化研：T6レーザー／量研関西研：J-KAREN-P）を照射する実験を実施し、生成するプラズマの基本特性（電子温度、イオンのエネルギー分布、Ｘ線強度分布など）を調べた。 その結果、10^19 W/cm^2領域のT6レーザー実験では、ロッド集合体の空間充填率を一定に保ちロッド径を小さくする（ロッド密度は増大）と電子温度は増加することが分かり、同じ平均密度でも構造の違いによって相互作用が異なることが分かった。また、10^21 W/cm^2領域のJ-KAREN-Pレーザー実験では、同じ空間充填率で異なったロッド径の集合体に同一条件のレーザーを照射した場合も異なるＸ線スペクトルが観測され、T6レーザー実験での結果と同様、ターゲットの構造によって電子温度などのプラズマ状態を制御可能であることが分かった。講演では、これらの実験結果の詳細を報告する。, 日本物理学会 2020年秋季大会

Abstract

宇宙線の起源として有力視されているのが、宇宙で生じる無衝突衝撃波である。特に、宇宙ジェットなどの超高速プラズマ中では、自己生成磁場を起因とする無衝突ワイベル衝撃波が生成されると考えられている。我々は高出力・高強度レーザーを用いて、高温、高エネルギー密度、超高速プラズマを生成することで、実験室に無衝突衝撃波を擬似的に再現し、その素過程を研究している（レーザー宇宙物理学）。無衝突ワイベル衝撃波の生成過程では、特有な電流フィラメントが生成される事が予想され、アメリカの大型ナノ秒レーザーOMEGAやNIFを用いた実験では、このフィラメント構造のプロトンバックライトによる計測や電子加速[2]が報告された。しかし、上述の実験ではショット数や時間・空間分解能の制限からワイベルフィラメントの詳細な時間・空間発展は得られていない。そこで我々は、播磨にあるX線自由電子レーザーSACLAと併設の高強度レーザー（最大出力500 TW）を用いたワイベルフィラメント計測実験を提案する。本提案ではサブピコ秒、数十nmでフィラメント構造を可視化する必要があり、SACLAによるX線小角散乱を計測する。その予備実験として、今回、ワイベルフィラメントを模擬したシリコンロッド集合体ターゲット（ロッド直径500 nmの円柱が1000 nm間隔に多数配置されたターゲット）に高強度レーザーを照射し、その時間発展をX線小角散乱によって計測した。, 日本物理学会 2020年秋季大会
