This paper explains an analytical formula for longitudinal coherent oscillations in an electron storage ring, including path-length oscillations. A path-length oscillation produced by closed orbit distortion was experimentally identified in the Ne...

The skew-quadrupole field errors in an undulator were determined from the response of the stored beam. This method used was to measure the change of the horizontal closed orbit distortion produced by two types of vertical local bump orbit in the u...
Optical alignment of the NewSUBARU beam-line 6 (BL6) is discussed by comparing the observed SR profiles with the calculated results of ray-tracing using SHADOW. A new screen monitor was mounted downstream of the first mirror to observe the synchro...
Coherent synchrotron radiation (CSR) in Tera-Hz region was observed at NewSUBARU. Three types of CSR from three types of electron beam were detected in the storage ring. One was a radiation burst from a high-density single-bunched beam. The burst ...
Some topics of the operational characteristics and improvements in these two years, in particular, vacuum and orbit, are summarized. The top-up operation realizes the constant flux of synchrotron radiation light at 1 GeV, then many experiments or ...

The synchrotron radiation facility NewSUBARU is a 1.5 GeV storage ring which has two long straight sections. A permanent magnet, planar-type, out-of-vacuum 10.8 m Long Undulator is placed in one of the long straight sections. The longitudinal mome...
