“…The crystal was seen by the detector through a collimating window of 5 mm diameter and 50 mm length. The semiconductor detector was calibrated by using the lines of characteristic radiation excited in a copper target by the proton beam (see [7]). The energy resolution of the detector for the 8.046 keV K α line was equal to about 250 eV.…”

“…The first experiment with the aim of PXR observation from heavy charged particles was carried out on the 70 GeV proton beam at IHEP [6]. Recently, PXR has been successfully observed from 5 GeV protons and 2.2 GeV/u carbon nuclei in a silicon crystal on the external beams of the Nuclotron at LHE JINR [7,8]. The characteristics of PXR are determined by the particle velocity v and they are independent of the charge sign and mass of the particle.…”

Spectral maxima of parametric X-ray radiation (PXR) produced by 400 GeV/c protons in bent silicon crystals aligned with the beam have been observed in an experiment at the H8 external beam of the CERN SPS. The total yield of PXR photons was about 10(-6) per proton. Agreement between calculations and the experimental data shows that the PXR kinematic theory is valid for bent crystals with sufficiently small curvature as used in the experiment. The intensity of PXR emitted from halo protons in a bent crystal used as a primary collimator in a circular accelerator may be considered as a possible tool to control its crystal structure, which is slowly damaged because of irradiation. The intensity distribution of PXR peaks depends on the crystal thickness intersected by the beam, which changes for different orientations of a crystal collimator. This dependence may be used to control crystal collimator alignment by analyzing PXR spectra produced by halo protons

“…In particular, PXR emitted by relativistic protons in crystals was observed in [6][7][8]. In the works [7,8] the semiconductor silicon detector used for the detection of PXR photons is 380 lm thick with a sensitive surface area of about 13 mm 2 and 25 lm beryllium window.…”
