Hadron Transverse Momentum Distributions in Muon Deep Inelastic Scattering at 160 GeV/$c$
/ COMPASS Collaboration
Multiplicities of charged hadrons produced in deep inelastic muon scattering off a $^6$LiD target have been measured as a function of the DIS variables $x_{Bj}$, $Q^2$, $W^2$ and the final state hadron variables $p_T$ and $z$. The $p_T^2$ distributions are fitted with a single exponential function at low values of $p_T^2$ to determine the dependence of $\langle p_T^2 \rangle$ on $x_{Bj}$, $Q^2$, $W^2$ and $z$. [...]

Fast Photon Detection for COMPASS RICH1

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

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.
