The threshold gas Cherenkov counter of charmonium experiment 835 at Fermilab
Abstract
A threshold gas Cherenkov counter is used in Fermilab experiment 835 to tag electrons from the decay of charmonium states. It is an improved version of the counter used in a previous charmonium experiment, E760. The new features of the design, the technique used to build a set of ellipsoidal mirrors, and the counter performance are presented.
