The article discusses the use of ultrafast photoemission spectroscopy and photon engineering techniques in the study of quantum materials. These techniques allow scientists to observe the development of electronic band structures and their occupancy over time, providing insights into non-equilibrium characteristics. The National Synchrotron Radiation Research Center in Taiwan is working on enhancing time-resolved spectroscopic methodologies, including the development of a time-resolved photoemission spectroscopy system and a time-resolved angle-resolved photoemission spectroscopy system. These systems aim to deepen our understanding of the electronic and dynamic characteristics of substances and their relationship with fundamental physical attributes. The article highlights the design and specifications of the Tr-ARPES setup, including the laser source, optics, and photon flux generation. The system offers high energy and temporal resolution, making it a powerful tool for studying quantum materials and driving innovation in various scientific and technological fields.

The article focuses on the construction of the second accelerator, the Taiwan Photon Source (TPS), at the National Synchrotron Radiation Research Center (NSRRC), which entered its third year of construction in 2012. It says that the TPS will be fitted with a low-emittance synchrotron storage ring and a three gigaelectronvolt (GeV) electron energy. It also mentions that the TPS is the solution to the problem of Taiwan regarding the long-term development of science and technology.

In 1983, the Taiwan government established the Synchrotron Radiation Research Center to begin the planning of a national synchrotron facility for soft X-ray and vacuum ultraviolet research. After several years of preparation, the Taiwan Light Source (TLS), a 1.3-GeV storage ring, became commissioned for user operation in October 1993. Since then, synchrotron radiation research has grown to become a major field of research in Taiwan. In May 2003, the synchrotron organization formally became one of seven national laboratories and was given the name National Synchrotron Radiation Research Center (NSRRC). This institutional establishment ensures continuous support by the government in terms of annual budget and future development of the Center. In December 2007, the government approved a new synchrotron project to construct a small-emittance 3-GeV storage ring, the Taiwan Photon Source (TPS). In this report, we briefly discuss in two parts the development of accelerator facilities, and the growth of user research programs at NSRRC. [ABSTRACT FROM AUTHOR]

Provides updates on recent developments of the Taiwan Light Source (TLS), a 3rd generation storage ring, at the National Synchrotron Radiation Research Center in Hsinchu, Taiwan. Projects completed to upgrade the performance of TLS; Current operation parameters of the storage ring; Improvement in the system reliability.

On the last day of 2014, the newly completed second accelerator of the National Synchrotron Radiation Research Center (NSRRC), Taiwan Photon Source (TPS), delivered its first synchrotron light in the early afternoon. The electron beam energy of the TPS circulating in the storage ring has reached the design value of 3 GeV, and the stored beam current has achieved over 5 mA, marking a significant milestone for Taiwan's new synchrotron light source. After nearly five years of construction and development efforts in full scale, the successful commissioning of TPS will forever change the course of scientific research in Taiwan.
