2. A modular software framework for the design and implementation of ptychography algorithms

Author: Guzzi, Francesco, Kourousias, George, Billè, Fulvio, Pugliese, Roberto, Gianoncelli, Alessandra, and Carrato, Sergio
Subjects: Computer Science - Computer Vision and Pattern Recognition, Physics - Applied Physics, Physics - Computational Physics, Physics - Data Analysis, Statistics and Probability
Abstract: Computational methods are driving high impact microscopy techniques such as ptychography. However, the design and implementation of new algorithms is often a laborious process, as many parts of the code are written in close-to-the-hardware programming constructs to speed up the reconstruction. In this paper, we present SciComPty, a new ptychography software framework aiming at simulating ptychography datasets and testing state-of-the-art and new reconstruction algorithms. Despite its simplicity, the software leverages GPU accelerated processing through the PyTorch CUDA interface. This is essential to design new methods that can readily be employed. As an example, we present an improved position refinement method based on Adam and a new version of the rPIE algorithm, adapted for partial coherence setups. Results are shown on both synthetic and real datasets. The software is released as open-source.

3. A parameter refinement method for Ptychography based on Deep Learning concepts

Author: Guzzi, Francesco, Kourousias, George, Billè, Fulvio, Pugliese, Roberto, Gianoncelli, Alessandra, and Carrato, Sergio
Subjects: Electrical Engineering and Systems Science - Image and Video Processing, Computer Science - Computer Vision and Pattern Recognition, Mathematics - Numerical Analysis, 68U10, 94A08, 92C55
Abstract: X-ray Ptychography is an advanced computational microscopy technique which is delivering exceptionally detailed quantitative imaging of biological and nanotechnology specimens. However coarse parametrisation in propagation distance, position errors and partial coherence frequently menaces the experiment viability. In this work we formally introduced these actors, solving the whole reconstruction as an optimisation problem. A modern Deep Learning framework is used to correct autonomously the setup incoherences, thus improving the quality of a ptychography reconstruction. Automatic procedures are indeed crucial to reduce the time for a reliable analysis, which has a significant impact on all the fields that use this kind of microscopy. We implemented our algorithm in our software framework, SciComPty, releasing it as open-source. We tested our system on both synthetic datasets and also on real data acquired at the TwinMic beamline of the Elettra synchrotron facility.

6. Visible pump -- mid infrared pump -- broadband probe: development and characterization of a three-pulse setup for single-shot ultrafast spectroscopy at 50 kHz

Author: Montanaro, Angela, Giusti, Francesca, Colja, Matija, Brajnik, Gabriele, Marciniak, Alexandre M. A., Sergo, Rudi, De Angelis, Dario, Glerean, Filippo, Sparapassi, Giorgia, Jarc, Giacomo, Carrato, Sergio, Cautero, Giuseppe, and Fausti, Daniele
Subjects: Physics - Optics, Condensed Matter - Superconductivity, Physics - Chemical Physics, Physics - Instrumentation and Detectors
Abstract: We report here an experimental setup to perform three-pulse pump-probe measurements over a wide wavelength and temperature range. By combining two pump pulses in the visible (650-900 nm) and mid-IR (5-20 $\mu$m) range, with a broadband supercontinuum white-light probe, our apparatus enables both the combined selective excitation of different material degrees of freedom and a full time-dependent reconstruction of the non-equilibrium dielectric function of the sample. We describe here the optical setup, the cryogenic sample environment and the custom-made acquisition electronics capable of referenced single-pulse detection of broadband spectra at the maximum repetition rate of 50 kHz, achieving a sensitivity of the order of 10$^{-4}$ over an integration time of 1 s. We demonstrate the performance of the setup by reporting data on mid-IR pump, optical push and broadband probe in a single-crystal of Bi$_2$Sr$_2$Y$_{0.08}$Ca$_{0.92}$Cu$_2$O$_{8+\delta}$ across the superconducting and pseudogap phases., Comment: 12 pages, 7 figures

10. Design of an FPGA-Based Controller for Fast Scanning Probe Microscopy.

Author: Gregorat, Leonardo, Cautero, Marco, Carrato, Sergio, Giuressi, Dario, Panighel, Mirco, Cautero, Giuseppe, and Esch, Friedrich
Subjects: SCANNING probe microscopy, FIELD programmable gate arrays, SCANNING tunneling microscopy, DIGITAL signal processing, ADATOMS
Abstract: Atomic-scale imaging using scanning probe microscopy is a pivotal method for investigating the morphology and physico-chemical properties of nanostructured surfaces. Time resolution represents a significant limitation of this technique, as typical image acquisition times are on the order of several seconds or even a few minutes, while dynamic processes—such as surface restructuring or particle sintering, to be observed upon external stimuli such as changes in gas atmosphere or electrochemical potential—often occur within timescales shorter than a second. In this article, we present a fully redesigned field programmable gate array (FPGA)-based instrument that can be integrated into most commercially available standard scanning probe microscopes. This instrument not only significantly accelerates the acquisition of atomic-scale images by orders of magnitude but also enables the tracking of moving features such as adatoms, vacancies, or clusters across the surface ("atom tracking") due to the parallel execution of sophisticated control and acquisition algorithms and the fast exchange of data with an external processor. Each of these measurement modes requires a complex series of operations within the FPGA that are explained in detail. [ABSTRACT FROM AUTHOR]

11. An End-to-End Workflow to Efficiently Compress and Deploy DNN Classifiers on SoC/FPGA.

Author: Molina, Romina Soledad, Morales, Ivan Rene, Crespo, Maria Liz, Costa, Veronica Gil, Carrato, Sergio, and Ramponi, Giovanni
Abstract: Machine learning (ML) models have demonstrated discriminative and representative learning capabilities over a wide range of applications, even at the cost of high-computational complexity. Due to their parallel processing capabilities, reconfigurability, and low-power consumption, systems on chip based on a field programmable gate array (SoC/FPGA) have been used to face this challenge. Nevertheless, SoC/FPGA devices are resource-constrained, which implies the need for optimal use of technology for the computation and storage operations involved in ML-based inference. Consequently, mapping a deep neural network (DNN) architecture to a SoC/FPGA requires compression strategies to obtain a hardware design with a good compromise between effectiveness, memory footprint, and inference time. This letter presents an efficient end-to-end workflow for deploying DNNs on an SoC/FPGA by integrating hyperparameter tuning through Bayesian optimization (BO) with an ensemble of compression techniques.

19. A high dynamic Micro Strips Ionization Chamber featuring Embedded Multi DSP Processing

Author: Voltolina, Francesco, Menk, Ralf H., and Carrato, Sergio
Subjects: Physics - Instrumentation and Detectors
Abstract: An X-ray detector will be presented that is the combination of a segmented ionization chamber featuring one-dimensional spatial resolution integrated with an intelligent ADC front-end, multi DSP processing and embedded PC platform. This detector is optimized to fan beam geometry with an active area of 192 mm (horizontal) and a vertical acceptance of 6 mm. Spatial resolution is obtained by subdividing the anode into readout strips, having pitch of 150 micrometers, which are connected to 20 custom made integrating VLSI chips (each capable of 64-channel read-out and multiplexing) and read out by 14 bits 10 MHz ADCs and fast adaptive PGAs into DSP boards. A bandwidth reaching 3.2Gbit/s of raw data, generated from the real time sampling of the 1280 micro strips, is cascaded processed with FPGA and DSP to allow data compression resulting in several days of uninterrupted acquisition capability. Fast acquisition rates reaching 10 kHz are allowed due to the MicroCAT structure utilized not only as a shielding grid in ionization chamber mode but also to provide active electron amplification in the gas., Comment: 5 pages, 7 figures, distilled by AFPL Ghostscript 7.04

22. A 3-year follow-up study on bone structure elastic quality

Author: Cosmi, Francesca, Gentile, Simona, Carrato, Sergio, Cosmi, Francesca, Gentile, Simona, and Carrato, Sergio
Subjects: Medical Devices, Bone, Osteoporosis, BES TEST®, Osteoporosi, Medical Device
Abstract: Osteoporosis is called a silent disease because bone fragility manifests itself to the patient only in an advanced state, through fracture and pain. Medical and industry leaders recognize that the current golden standard diagnostic method, densitometry, or Dual Energy X-ray Absorptiometry (DEXA), may not always be sufficient to assess the patient’s real risk of fragility fracture [1]. Indeed, pathological alterations affect not only the mineral content (quantity) of the bone, but also its “quality”, which can be measured from the elastic properties of the bone internal trabecular structure by means of the Bone Elastic Structure Test, BES TEST®. In this study, the incidence of fragility fractures was assessed after a 3-year follow-up period in the women enrolled for a population study in 2015. The BES TEST® resulted an effective estimator of bone health, and can improve the assessment of the patient’s fracture risk map.

42. Design of High Dynamic Range Preamplifiers for a Diamond-Based Radiation Monitor System

Author: Marich, Marco, Bosisio, Luciano, Brajnik, Gabriele, Carrato, Sergio, Cautero, Giuseppe, Gabrielli, Alice, Giuressi, Dario, Jin, Yifan, Lanceri, Livio, and Vitale, Lorenzo
Subjects: 04 Beam Loss Monitors and Machine Protection, Accelerator Physics
Abstract: Regardless of the different accelerator types (light sources like FELs or synchrotrons, high energy colliders), diagnostics is an essential element for both personnel and machine protection. With each update, accelerators become more complex and require an appropriate diagnostic system capable of satisfying multiple specifications, that become more stringent as complexity increases. This paper presents prototyping work towards a possible update of the readout electronics of a system based on single-crystal chemical vapor deposition (scCVD) diamond sensors, monitoring the radiation dose-rates in the interaction region of SuperKEKB, an asymmetric-energy electron-positron collider. The present readout units digitize the output signals from the radiation monitors, process them using an FPGA, and alert the accelerator control system if the radiation reaches excessive levels. The proposed updated version introduces a new design for the analog front end that overcomes its predecessor’s limits in dynamic range thanks to high-speed switches to introduce a variable gain in transimpedance preamplifiers, controlled by an ad-hoc developed FPGA firmware., Proceedings of the 11th International Beam Instrumentation Conference, IBIC2022, Kraków, Poland

43. Design and Implementation of an FPGA-Based Digital Processor for BPM Applications

Author: Colja, Matija, Brajnik, Gabriele, Carrato, Sergio, and De Monte, Raffaele
Subjects: 02 Beam Position Monitors, Accelerator Physics
Abstract: Digital processing systems have been proven to often outperform analog elaboration. Indeed, thanks to high-density DSPs and FPGAs, operations in digital domain give results that are impossible to achieve in other ways. On the other side, dealing with this great performance and flexibility is not always straightforward: the processing chain needs to be accurately planned to reach the desired goals, avoiding erratic behaviours in the digital domain. In this paper, we focus on the design and implementation of an FPGA-based digital processor that will be used in the electron beam position monitors of Elettra 2.0. After digitizing the 500 MHz beam signals from the pickups, the system executes a digital down conversion, followed by several filtering and demodulating stages, in order to have a selectable data rate that is suitable for both diagnostics and feedback. The position calculation is also performed in FPGA as well, with the well-known difference-over-sum algorithm. According to results provided by a fixed-point simulation, the overall system has been implemented in an Intel Arria 10 FPGA, demonstrating the correct design functionality that meets the specified requirements., Proceedings of the 11th International Beam Instrumentation Conference, IBIC2022, Kraków, Poland
