Description
TRDs are commonly used in PID applications, exploiting the threshold Lorentz factor for TR emission. Since TR X-rays have energies from a few keV to a few tens of keV, TRDs are usually equipped with gaseous detectors.
Recently, new techniques for measuring the TR with solid state detectors have been successfully implemented. High-granularity semiconductor pixel or microstrip detectors provide spatial separation of the TR photons and ionization losses, even with limited radiator-detector distances. These detectors may be the basis for novel devices combining precise tracking and PID properties. The presence of a magnetic field could enhance the separation between TR photons and dE/dx losses.
Highly segmented solid state detectors have high efficiency of the TR X-ray detection. Simultaneous measurements of the TR X-ray energies and production angles may significantly improve the PID capabilities and allow to extend the application of TRDs to hadron separation in the TeV momentum region.
