Hsieh, F

After the current Tevatron collider run, the D0 detector will undergo a major upgrade, including a central tracker with a magnetic field. Between the new solenoid and the existing central calorimeter cryostat, a preshower detector will be added to recover otherwise unsampled energy and to improve electron identification. Current design of the preshower detector is to have axial and stereo scintillator strips with wavelength shifter (WLS) fiber readout into Visible Light Photon Counters (VLPCs). In this talk, the author presents cosmic ray test results from a preshower prototype module. This prototype module consists of several permutations of scintillator, WLS fiber and construction techniques. The test was conducted in the Existing D0 cosmic ray test stand, which includes precise tracking and crude energy determination. The results of light yield, cross-talk, angle of incidence, attenuation and spatial uniformity effects will be presented. Test results show that light yields of 15-20 photoelectrons are easily achievable.
