A high-repetition-rate X-ray chopper system has been developed for pump-probe time-resolved measurements with synchrotron radiation. This system has a rotating disc with 108 or 54 grooves (X-ray path on the disc) that provides an opening time of 1.17 or 0.52 mu s with a rotating speed of 28,997 rpm. Also, this system could select single-pulse X-rays every 4 or 8 periods of the several-bunch structure operated at SPring-8, corresponding to an X-ray pulse frequency of 52.2 or 26.1 kHz, respectively, and is suitable for pump-probe studies of electronic devices such as next-generation memory devices.
