WebJul 11, 2024 · A double-layer gas electron multiplier (GEM) chamber was developed at the Physics Department, Changwon National University. Its performance was evaluated using Cs-137 and Sr-90 radiation sources. Using a gas mixture filling of 85% argon and 15% carbon dioxide, in the one-channel GEM chamber (5 cm × 5 cm), the pulse height distributions … WebJan 1, 1989 · Calculated channel electron multiplier efficiency as a function of the multiplier voltage assuming a Gaussian pulse height distribution. The curves show the need for a higher multiplier voltage as the energy, E, of the incident electrons is reduced. where k is a constant which incorporates h^, Q represents the integral shown and So is the pulse rate …
