Development of a position sensitive multi-wire cathode strip detector for fission fragments

We have developed a large area 2-dimensional position sensitive multi-wire cathode strip detector (MCSD) for the detection of fission fragments (FFs). The performance characteristics of the detector has been studied with FFs from ²⁵²Cf source. The position information is obtained from the measurement of time delay signals of the cathode strips (X-direction) and split-cathode wires (Y-direction) with respect to the timing signal from the anode wires. The position resolution is found to be about 1.0 and 1.5 mm in X and Y-directions respectively. The detector has been used for measuring FFs produced in heavy-ion induced experiments in ^6,7Li+²³²Th reactions at energies around the Coulomb barrier. (author)
