Abstract :
A detector system has been developed for the focal plane of the HIRA. It consists of two independent detectors, a low-pressure multiwire proportional counter (LP-MWPC) followed by a split-anode ionization detector. Details of the design and test results are presented. Using slow preamplifiers, the position resolution is ≥1 mm and the time resolution is estimated to be 1.5 ns for the LP-MWPC. The ionization detector gives 2.4% energy resolution for 150 MeV 28Si scattered off a gold target and the ΔZ/Z obtained for 28Si + 27Al is 142 for Z = 14. Some results for fusion and transfer studies for the 48Ti + 58Ni and 28Si + 68Zn systems, respectively, at energies around the Coulomb barrier, are presented to highlight the performance of the detector system.
