Abstract :
A single-pass beam-position monitor (BPM) system for the injection beam was developed. The injection orbit during the 1st turn to the 4th turn could be measured with a single injection pulse. The resolution of the measurement was estimated to 0.15 mm for the electron beam. The injection orbit at the usual operation condition was measured and was confirmed to coincide with the design orbit. A trial of the on-axis injection with a DC bump was performed. The orbit correction based on the single-pass measurement was attempted by using the best corrector method
