We report on studies of layout and performance of a new Ring Imaging Cherenkov detector using for the fi rst time pressurized C 4 F 8 O radiator gas and a photon detector consisting of a MWPC equipped with a CsI photocathode. In particular, we present here the results of beam tests of a MWPC having an adjustable anode – cathode gap, aiming at the optimization of single photoelectron detection and Cherenkov angle resolution.

/ Acconcia, T V (U. Campinas) ; Agócs, A G (Wigner RCP, Budapest) ; Barile, F (Bari U. ; INFN, Bari) ; Barnaföldi, G G (Wigner RCP, Budapest) ; Bellwied, R (Houston U.) ; Bencédi, G (Wigner RCP, Budapest) ; Bencze, G (Wigner RCP, Budapest) ; Berényi, D (Wigner RCP, Budapest) ; Boldizsár, L (Wigner RCP, Budapest) ; Chattopadhyay, S (Saha Inst.) et al.
A small-size prototype of a new Ring Imaging Cherenkov (RICH) detector using for the first time pressurized C4F8O radiator gas and a photon detector consisting of MWPC equipped with a CsI photocathode has been built and tested at the PS accelerator at CERN. It contained all the functional elements of the detector proposed as Very High Momentum Particle Identification (VHMPID) upgrade for the ALICE experiment at LHC to provide charged hadron track-by-track identification in the momentum range starting from 5 potentially up to 25 GeV/c.

The VHMPID RICH upgrade project for ALICE at LHC
/ Di Mauro, A (CERN) ; Nappi, E (INFN, Bari ; Bari U.) ; Levai, P (Budapest, RMKI) ; Smirnov, N (Yale U.) ; Pochybova, S (Budapest, RMKI) ; Futo, E (Budapest, RMKI) ; Son, C (Pusan Natl. U.) ; Boldizsar, L (Budapest, RMKI) ; Volpe, G (INFN, Bari ; Bari U.) ; Lipusz, C (Budapest, RMKI) et al.
RHIC results have shown the importance of high momentum particles as hard probes and the need for particle identification (PID) in a very large momentum range. A Very High Momentum PID (VHMPID) detector has been proposed as upgrade of ALICE to extend the track-by-track identification capabilities for charged hadrons from the presents GeV/c limit to the momentum range 10-30 GeV/c.

We report on the R&D; results for a Very High Momentum Particle Identification (VHMPID) detector, which was proposed to extend the charged hadron track-by-track identification in the momentum range from 5 to 25 GeV/ c in the ALICE experiment at CERN. It is a RICH detector with focusing geometry using pressurized perfluorobutane (C 4 F 8 O) as a Cherenkov radiator. [...]

First observation of Cherenkov rings with a large area CsI-TGEM-based RICH prototype

We have built a RICH detector prototype consisting of a liquid C6F14 radiator and six triple Thick Gaseous Electron Multipliers (TGEMs), each of them having an active area of 10x10 cm2. One triple TGEM has been placed behind the liquid radiator in order to detect the beam particles, whereas the other five have been positioned around the central one at a distance to collect the Cherenkov photons.

Very high momentum particle identification at the LHC
/ ALICE VHMPID Collaborations
The anomalies observed at RHIC for the baryon — meson ratios have prompted a number of theoretical works on the nature of the hadrochemistry in the hadronisation stage of the pp collisions and in the evolution of the dense system formed in heavy ion collisions. Although the predictions differ in the theoretical approach, generally a substantial increase in the baryon production is predicted in the range 10–30 GeV/c. [...]
