N1 - Funding Information:
A large Cherenkov counter has been designed as a forward direction trigger for the SDC detector which has the desirable property that it does not detect the signals from the large number of background low momentum particles while it is fully efficient for muons with momenta above 50 GeV/c. These low momentum background particles are always present behind the heavy material of an SDC like detector associated with a high energy collision at the interaction point. In the SDC Cherenkov counter design, each cell consists of an array of four spherical mirrors, with a focal length of 140 cm, aligned so that the Cherenkov light from a very high energy muon is focused on the surface of a * Research Supported by the Dept of Energy Contract DE-AC02-86ER40253 and the Texas National Research Labo-ratory Comission grants RCFY9102 and RCFY9105 .

N2 - A test of a gas Cherenkov counter was performed at Fermilab in the High Energy Muon Lab in order to understand its performance as a trigger counter for muons above a given momentum. This counter was built so that it could rotate relative to the beam direction to simulate the bending of muon tracks in the toroidal magnet of the Solenoidal Detector Collaboration (SDC) being designed for use at the Superconducting Super Collider (SSC). The SDC Cherenkov counter is so designed that a high momentum muon would emit Cherenkov light that is focussed on the face of a photomultiplier tube while a low momentum muon in the forward element of the SDC detector is bent to large enough angles so that the light is focused away from the photomultiplier tube. We present the observed changes in pulse height as the counter is rotated and the simulated resultant trigger efficiency for a given photomultiplier output pulse.
