Performance of the Cherenkov counters in the fermilab tagged photon spectrometer facility
Abstract
We describe the performance of the Cherenkov counters used in a study of charm photoproduction at Fermilab. We concentrate our discussion on the construction and performance of the Winston cone-phototube elements and the mirrors. We present, based on data from experiment E691, the number of photoelectrons observed in the various cells and discuss in detail the usefulness of these counters in accenting the charm signals.
