Outline of Annual Research Achievements

We performed two experiments: 1. NewSUBARU, Japan: Characterization of XCCD and spectrograph used in our 2021 UK experiment; 2. J-KAREN-P, Japan: BISER coherent x-ray source jointly with ELI (Czechia) and NTU (Taiwan).
As planned, we installed the large deformable mirror to the J-KAREN-P laser and improved its focal spot. We implemented advanced diagnostics: optical probe with ~1-2um spatial and ~15fs temporal resolution, and improved plasma imaging with ~1um resolution. We made a higher-efficiency keV VLS grating and obtained modulated keV BISER spectra. We achieved 5x higher BISER yield compared to the previous record (2022).
As planned, we reduced the XUV imager stray light and obtained XUV diffraction patterns of 3-period grating with much higher SN ratio, which is a foundation of the attosecond lensless imaging. We recorded BISER source images and, for the 1st time, XUV spectrum on the high-resolution LiF detector.
Compared to the previous experiment (2022), we further improved the Magnetic Bottle Electron Spectrometer (MBES) resolution and SN ratio and observed Auger lines of BISER-irradiated Xe; this is a foundation of the attosecond BISER pulse measurement.
We published 5 refereed papers: [HPLSE accepted] on diagnostics of relativistic plasma singularities using compressed optical probe; [RSI 2023; RSI 2024] on x-ray spectroscopy and instruments; [HPLSE accepted] on precise target positioning in relativistic laser-plasma experiments using optical and x-ray diagnostics; [Photonics 2023] on developing of our BISER driving laser.
