Title: Close Cathode Chamber: cost efficient and lightweight detector for tracking applications
Abstract content The Close Cathode Chamber (CCC) is an asymmetric Multi-Wire Proportional Chamber (MWPC), which, owing to its specifically optimized field structure, has key advantages relative to the classical MWPC design. The CCC contains alternating field wires and anode (sense) wires, and the wire plane is asymmetric with respect to two parallel planes, being as close as 1.5mm typically to one of the planes for 2mm wire spacing. We have shown that this arrangement minimizes the dependence of the avalanche gain on detector wall planarity [1], and specifically, insensitivity to corresponding mechanical distortions or internal overpressure (causing bulging). Such feature allows one to build CCC chambers with small overall material budget, avoiding also the thick frames typical for MWPC-s. Careful studies confirmed that signal formation and position resolution correspond to that in classical MWPC-s. The dead zones created by internal support structures have been evaluated [2]. CCC detectors have found application in a portable cosmic muon tracking system [3],[4], proving their mechanical and operational stability under hars and varying environmental conditions.
