Test of an optical transition radiation detector for high-intensity proton beams at FNAL

Initial results are presented of a prototype optical transition radiation (OTR) detector under development at Fermi National Accelerator Laboratory (FNAL). The purpose of this prototype detector is to evaluate the feasibility of using OTR imaging of proton (or antiproton) beams in transport lines for beam position and shape measurements. A secondary purpose is to develop experience in designing, constructing and operating a camera and optics system in high radiation environments. Measurements are made of 120 GeV proton beams with up to 4.7 × 10¹² particle intensities. Data are presented of OTR with titanium and aluminum foils.
