A dielectric\, which is widely used for high- power lasers\, is therefore the choice of material for an accelerator oper ating at the optical frequencies. Owing to the much shorter drive waveleng th\, a dielectric laser accelerator (DLA) built upon a photonic chip could produce nano-electron bunches useful for studying attosecond science or g enerating electron superradiance in the EUV and soft x-ray spectrum. We sh ow in this presentation that\, in the low-current limit\, a DLA-driven pho tonic chip can generate laser-like radiation from a single electron and a train of single electrons\; where\, with ~fC bunch charge\, DLA-driven coh erent undulator radiation is the brightest photon source on Earth when the brilliance of radiation per beam power is considered.\n\nhttps://indico.n srrc.org.tw/event/16/contributions/246/ LOCATION:Activity Center Room D260 URL:https://indico.nsrrc.org.tw/event/16/contributions/246/ END:VEVENT BEGIN:VEVENT SUMMARY:Present and Future of Pohang Accelerator Laboratory DTSTART;VALUE=DATE-TIME:20240418T010000Z DTEND;VALUE=DATE-TIME:20240418T014000Z DTSTAMP;VALUE=DATE-TIME:20260907T003737Z UID:indico-contribution-442-245@indico.nsrrc.org.tw DESCRIPTION:Speakers: Heung-Sik Kang (Pohang Accelerator Laboratory)\nPAL\ , established in 1988 with full support from the Pohang University of Scie nce and Technology\, has acted as a powerhouse to support basic science an d technology in Korea and has secured a competitive edge frontier after ma king ceaseless efforts. PAL is now operating PLS-II and PAL-XFEL.\n\nPLS-I I is the 3-rd generation synchrotron with 3-GeV beam energy and 5.8 nm emi ttance. Thirty-six beamlines are operational for user-service operation. P AL-XFEL is a hard X-ray free-electron laser facility based on 10-GeV norma l conducting linac. One hard X-ray and a soft X-ray FEL are operational fo r user-service operation.\n\nThe PAL-XFEL has demonstrated excellent timin g stability and unprecedented peak brightness since its start of user serv ice operation in June 2017\, outperforming other XFEL facilities worldwide . The 18-fs timing stability in the XFEL allows excellent pump-probe time- resolved experiments with low-timing jitter. A self-seeding scheme enables us to produce a higher peak brightness of the XFEL with a narrow bandwidt h: the peak brightness of 3.2 x 1035 photons/(s·mm2·mrad2·0.1%BW) at 9. 7 keV and the bandwidth of 0.19 eV\, the best to date. To provide more bea mtime to users\, we started the 2nd hard X-ray FEL line project in 2024 an d will finish it by 2027.\n\nFor our current or potential scientific users \, we will continue to strengthen our capacity\, scientific programs\, and industry engagement and maximize our impact as a major contributor to the cutting-edge future of science in Korea.\n\nhttps://indico.nsrrc.org.tw/e vent/16/contributions/245/ LOCATION:Activity Center Room D260 URL:https://indico.nsrrc.org.tw/event/16/contributions/245/ END:VEVENT END:VCALENDAR
