The Tevatron Ionization Profile Monitors

In designing an ionization profile monitor system for the Tevatron some novel approaches were taken, in particular for the readout electronics. This was motivated by the desire to resolve the individual bunches in both proton and pbar beams simultaneously. For this purpose, custom‐made electronics originally developed for Particle Physics experiments was used to provide a fast charge integration with very low noise. The various parts of the readout electronics have been borrowed or adapted from the KTev, CMS, MINOS and BTev experiments. The detector itself also had to be modified to provide clean signals with sufficient bandwidth. The system design will be described along with the initial results.
