Particle identification with the Silicon Transition Radiation Detector (SiTRD): State of art and future perspectives

We are developing a novel Transition Radiation Detector (SiTRD) based on silicon strip detectors (SSDs) operated in a magnetic field region. In this way the trajectory of the radiating particle is deflected with respect to the Transition Radiation X-rays that are absorbed in a detector region far away from the particle track. The SiTRD combines the particle identification performance of a traditional TRD with the high-precision tracking capability of SSDs, and it can be suitable for both accelerator and cosmic ray experiments, whenever particle identification and momentum reconstruction are required. In this paper we will show the experimental results obtained with a reduced scale SiTRD prototype exposed to an electron–pion beam.
