Abstract

A new beam position monitor digitizer module has been designed, tested and tuned at SLAC. This module, the electron-positron beam position monitor (epBPM), measures position of single electron and positron bunches for the SLC, linac, PEP II injection lines and final focus. The epBPM has been designed to improve resolution of beam position measurements with respect to existing module and to speed feedback correction. The required dynamic range is from 5×10⁸ to 10¹¹ particles per bunch (46 dB). The epBPM input signal range is from ±2.5 mV to ±500 mV. The pulse-to-pulse resolution is less than 2 μm for 5×10¹⁰ particles per bunch for the 12 cm long striplines, covering 30° at 9 mm radius. The epBPM module has been made in CAMAC standard, single width slot, with SLAC type timing connector. 45 modules have been fabricated
