ALICE/HMPID concept of CsI RICH

- liquid C6 F14 radiator- proximity focussing geometry- small gap MWPC (~2 mm)

- cathode pads coated with CsI

NA44 / TIC @ CERN (0.3 m2) finished

STAR / RICH @ BNL (1 m2) running

PHENIX / HBD @ BNL (0.7 m2) running

HADES / RICH @ GSI (1.5 m2) running

ALICE / HMPID @ CERN (11m2) in preparation

COMPASS / RICH1 @ CERN (5.8 m2) runningExperiments with CsI RICH

(active area m2)

MWPC

front-end electronics

pad cathode covered with CsI film

PHENIX HBD Concept @ BNL

-CsI coated directly on GEM-CF4 gas as radiator -Reverse drift field (Hadron blind)-Proximity focussing geometry (leptons produce a blob of 35 photons in about 10 cm2)

CBM Experiment

GEM Simulations

• MAXWELL to produce a 2D and/or 3D field mapping

• MAGBOLTZ to produce gaseous data

• GARFIELD to see the detector response
