The article presents the results on the investigation of the channeling and volume reflection effects in a bent silicon crystal with 13 GeV/c positive and negative hadrons (mainly pi+, p and pi-) at the CERN PS T9 line. In particular, this is the first study carried out on volume reflection at this energy providing a deflection angle of 69.4 ± 4.7 lrad and an efficiency of 92.7 ± 3.3%, with positive particles. The measurements have been carried out on a bent silicon strip crystal, using a high precision tracking system based on microstrip silicon detectors; this setup is allowed to trigger on the desired beam portion and to select the incoming particle angular range. The article presents a brief introduction on the bent crystal phenomena, the experimental setup and the results of the measurements.

Abstract

The article presents the results on the investigation of the channeling and volume reflection effects in a bent silicon crystal with 13 GeV/c positive and negative hadrons (mainly pi+, p and pi-) at the CERN PS T9 line. In particular, this is the first study carried out on volume reflection at this energy providing a deflection angle of 69.4 ± 4.7 lrad and an efficiency of 92.7 ± 3.3%, with positive particles. The measurements have been carried out on a bent silicon strip crystal, using a high precision tracking system based on microstrip silicon detectors; this setup is allowed to trigger on the desired beam portion and to select the incoming particle angular range. The article presents a brief introduction on the bent crystal phenomena, the experimental setup and the results of the measurements.
