Properties of argon-bromine counters

Summary Argon-bromine counters are compared with argon-alcohol counters. The point is stressed that their properties change when the charge developed in the counter becomes equal to or greater than the charge originally present at the wire. The so-called oscillations are investigated and partially explained as well as the delay in the build-up of a pulse, this delay being dependent on the overvoltage. A clear-cut picture of the mechanism of these counters can not yet be given.
