Abstract

The plane grating monochromator (PGM) is one of the most useful monochromators in the world. The design concept of the PGM originates from the characteristics of synchrotron radiation itself, namely parallel rays and small source size. Since the performance of the PGM depends on the beam emittance of the storage ring, it is expected that even the used PGM may be utilized in recent facility. Therefore, the UVSOR‐type PGM that had been used for more than twenty years in UVSOR was adapted to the university’s branch beamline in Saga‐LS with several modifications. The performance tests were carried out with a photoelectron spectrometer, and the observed values were compared with the ray‐tracing calculation. The results show that the adaptation of the UVSOR‐type PGM is good enough to study new functional materials.
