Abstract
Operating conditions and challenging demands of present and future accelerator experiments result in new requirements on detector systems. There are many ongoing activities aimed to develop new technologies and to improve the properties of detectors based on existing technologies. Our work is dedicated to development of Transition Radiation Detectors (TRD) suitable for different applications. In this paper results obtained in beam tests at SPS accelerator at CERN with the TRD prototype based on straw technology are presented. TRD performance was studied as a function of thickness of the transition radiation radiator and working gas mixture pressure.
Highlights
Particle identification with Transition Radiation Detectors (TRD) is based on the difference of energies deposited in detector module(s) crossed by particles with different gamma factors
This paper presents the results on the studies of detector performance with different radiator thicknesses and different working gas pressures
Transition Radiation Detector prototype based on straw tubes was tested with 20 GeV pion and electron beams at CERN SPS accelerator
Summary
Particle identification with TRDs is based on the difference of energies deposited in detector module(s) crossed by particles with different gamma factors. Typical resulting spectra of energy depositions for different particle types in straw detector are shown in figure 1. This paper presents the results on the studies of detector performance with different radiator thicknesses and different working gas pressures.
