A 14-channel threshold gas Cerenkov counter filled with Freon-12 at a pressure of 1 atm is described. The radiator length is 150 cm. The counter efficiency for protons with a momentum of circa equal to or greater than 30 GeV/c exceeds 98%. The counter is a part of the system for identification of secondary charged particles of the BIS-2 spectrometer of the Institute of HighEnergy Physics. A diagram of the counter and its dimensions is shown. The counter consists of a light- and gasproof housing, a set of focusing mirrors, and a photomultiplier system.
