Abstract :
An optical transition radiation (OTR) detector has been installed in the FNAL AP-1 pre-target beamline to image OTR from 120 GeV protons used for antiproton production. This detector will be used to measure protons-on-target beam profiles at high intensities where the present secondary emission monitor (SEM) will not operate. This detector will complement the AP-1 beam instrumentation that includes 2 toroids, 6 secondary emission monitors, 9 beam position monitors (BPM), 24 beam loss monitors (BLM) and a resistive wall monitor (RWM). The AP-1 beamline is a 120 GeV high-intensity fixed-target proton beamline with the following beam parameters: a maximum expected beam intensity of 1e13 protons/spill, spill rate of 1.9 seconds, and a spill length 1.6 musec. Commissioning of the OTR system is proceeding and initial results are presented.
