Abstract

The Alternating Gradient Synchrotron (AGS) booster ionization profile monitor (IPM) must operate in a vacuum of about 3*10/sup -/0/sup 11/ Torr. The authors present details of the design of the profile monitor. The ultra-high vacuum imposes certain requirements on detector gain and restrictions on construction techniques. Each detector is a two-stage microchannel plate with an integral substrate containing sixty-four printed anodes. Formed electrodes provide uniform collection fields without the use of resistors, which would be unacceptable in these vacuum conditions. An ultraviolet light calibrates the detector in its permanent mounting. An extra set of electrodes performs a first order correction to the perturbations imposed by the horizontal and vertical collection electrodes.<>
