Study on the large position sensitive detector

Technical Report:

Abstract

A large position sensitive detector, in which the charge division technique is used, with a single wire anode proportional counter is developed. The sensitive area of the detector is 1200 x 60 mm{sup 2}. The anode of the detector is NiCr wire with 10 {mu}m in diameter and 12 {Omega}/mm of its resistance. The cathodes of the detector are single side aluminized Mylar films and the thickness 12.5 {mu}m. The detector works under the condition of flushing the mixed gas of 70% Ar + 30% CH{sub 4} with one atmosphere. In order to test the detector a {sup 241}Am alpha source (about 5 MeV) is put on the collimator. The collimator can freely and accurately move along the detector window. Along the direction of anode wire, measurement is performed in the distance of every 6 cm. The total is 19 measuring points. The average intrinsic position resolution (FWHM) is about 0.6 mm, and the integral nonlinearity is better than 0.2%. This detector has been installed on the detector system of Q3D magnetic spectrometer and will be tested on the tandem accelerator with ion beam.
