/ Aad, G. (Marseille, CPPM) ; Akimov, A.V. (CERN ; LPI, Moscow (main)) ; Al Khoury, K. (Nevis Labs, Columbia U.) ; Aleksa, M. (CERN) ; Andeen, T. (Arizona U.) ; Anelli, C. (Victoria U.) ; Aranzabal, N. (CERN) ; Armijo, C. (Arizona U.) ; Bagulia, A. (Lebedev Inst.) ; Ban, J. (Nevis Labs, Columbia U.) et al.
The Phase-I trigger readout electronics upgrade of the ATLAS Liquid Argon calorimeters enhances the physics reach of the experiment during the upcoming operation at increasing Large Hadron Collider luminosities. The new system, installed during the second Large Hadron Collider Long Shutdown, increases the trigger readout granularity by up to a factor of ten as well as its precision and range. [...]

Trieste (main)) ; Colantoni, M L (INFN, Turin) et al.
A fast photon-detection system for the detector RICH-1 of the COMPASS Experiment at CERN SPS is in operation since the 2006 run. It is based on the use of Multi-Anode Photomultipliers (MAPMTs) coupled to individual fused silica lens telescopes and fast read-out electronics. [...]

Fast Photon Detection for COMPASS RICH1
/ Abbon, P (DSM, DAPNIA, Saclay) ; Alekseev, M (INFN, Turin ; Turin U.) ; Angerer, H (Munich, Tech. U.) ; Apollonio, M (INFN, Trieste ; Trieste U.) ; Birsa, R (INFN, Trieste ; Trieste U.) ; Bordalo, P (Lisbon, LIFEP) ; Bradamante, F (INFN, Trieste ; Trieste U.) ; Bressan, A (INFN, Trieste ; Trieste U.) ; Busso, L (INFN, Turin ; Turin U.) ; Chiosso, M (INFN, Turin ; Turin U.) et al.
The new photon detection system for COMPASS RICH-1 has been designed to cope with the demanding requests of operation at high beam intensity and at high trigger rates. The detection technique in the central region of RICH-1 has been changed with a system based on multianode photomultipliers coupled to individual fused silica lens telescopes and to a fast, almost dead time free readout system based on the MAD-4 amplifier-discriminator and the F1 TDC-chip.

Optical telescopes for COMPASS RICH1 up-grade
/ Sulc, M (Liberec Tech. U.) ; Abbon, P (DSM, DAPNIA, Saclay) ; Alekseev, M (INFN, Turin ; Turin U.) ; Angerer, H (Munich, Tech. U.) ; Appolonio, M (INFN, Trieste ; Trieste U.) ; Birsa, R (INFN, Trieste ; Trieste U.) ; Bordalo, P (Lisbon, LIFEP) ; Bradamante, F (INFN, Trieste ; Trieste U.) ; Bressan, A (INFN, Trieste ; Trieste U.) ; Busso, L (INFN, Turin ; Turin U.) et al.
The central photon detection area of the Ring Imaging Cherenkov detector at COMPASS, a particle physics experiment at CERN SPS dedicated to hadron physics, has been upgraded from the previous system formed by wire chambers with CsI layers to a very fast UV extended multi anode photo multiplier tube array (MAPMT), including 576 tubes. The active area covered by the MAPMTs is 7.3 times smaller than the one previously equipped with CsI photocathodes, so 576 optical concentrators transforming the image from the old system focal plane to the new photocathode plane were needed.

COMPASS RICH-1 is a large size gaseous Imaging Cherenkov Detector providing hadron identification in the range from 3 to 55 GeV/c, in the wide acceptance spectrometer of the COMPASS Experiment at CERN SPS. It uses a 3 m long C(4)F(10) radiator, a 21 m(2) large VUV mirror surface and two kinds of photon detectors: MAPMTs and MWPCs with CsI photocathodes, covering a total of 5.5 m(2). [...]
