Abstract :
A beam-position monitor (BPM) has been installed in the transport lines between the Accumulation Ring (AR) and the Main Ring (MR) of TRISTAN. This monitor comprises stripline and button electrodes, detectors and charge-sensitive accuracy ADCs. The detector is a homodyne type synchronous-receiver resolution at 70 MHz with four channels corresponding to four electrodes. Operation software automatically displays the detected beam position and its charge on a TV screen after each passage of the beam. The system is stable and is used to monitor the drift of the beam position. This is a brief report on the monitor
