Beam tests of an integrated prototype of the ATLAS Forward Proton detector
Original language description
The ATLAS Forward Proton (AFP) detector is intended to measure protons scattered at small angles from the ATLAS interaction point. To this end, a combination of 3D Silicon pixel tracking modules and Quartz-Cherenkov time-of-flight (ToF) detectors is installed 210m away from the interaction point at both sides of ATLAS. Beam tests with an AFP prototype detector combining tracking and timing sub-detectors and a common readout have been performed at the CERN-SPS test-beam facility in November 2014 and September 2015 to complete the system integration and to study the detector performance. The successful tracking-timing integration was demonstrated. Good tracker hit efficiencies above 99.9% at a sensor tilt of 14 degrees, as foreseen for AFP, were observed. Spatial resolutions in the short pixel direction with 50 mu m pitch of 5.5 +/- 0.5 mu m per pixel plane and of 2.8 +/- 0.5 mu m for the full four-plane tracker at 14 degrees were found, largely surpassing the AFP requirement of 10 mu m. The timing detector showed also good hit efficiencies above 99%, and a full-system time resolution of 35 +/- 6 ps was found for the ToF prototype detector with two Quartz bars in-line (half the final AFP size) without dedicated optimisation, fulfilling the requirements for initial low-luminosity AFP runs.
