Abstract
This detector comprises a gas chamber (2) containing plane electrodes (4, 6, 8) delimiting conversion (C) and amplification (A) gaps. One of the electrodes is perforated with holes (18) and forms the detector cathode (6). The distance between the detector cathode and the anode (8) is less than 500 μm. The intensity of the electric field in the amplification gap is ten times higher than the intensity of the electric field in the conversion gap. Application in particle physics, medicine, biology.
