TOF wall for CBM
B. Zagreev (ITEP) Matching
G. Stoicea (IFIN) Geometry
Distance to closest hit
Choose different concepts for different polar
angles! Standard material properties sufficient
for 70 of solid angles. Most effective layout
needs to be found!
9
Toward the Technical Report
Layout of CBM TOF wall fully unrealistic to
have a CBM - TOF detector concept within 2
month! Collection of available information
possible until Jan. 2005 (task force)
Properties of Pad readout B.
Zagreev narrow multi strips M. Petrovici, A.
Schuettauf wide strips R. Marques, P.
Fonte Material F. Guber Electronics (NN
) Test facilities F. Dohrmann (some of the
quantities like cross talk, full size
efficiency, full size time resolution, double hit
capability, ... might still have to be
measured)

Plans
INR, ITEP, IHEP Single cell RPC with silicate
glass Dec. 2004 GSI, HD Test of FOPI full
scale prototype (multi-strip RPC)
Nov.2004 Multihit performance of narrow strip
designs Rossendorf prepare testing
facility ready for users Summer
2005 Coimbra HADES single strip
prototype Spring 2005 High rate properties
with non-glass material Temperature dependence
(Limits, ageing,long term stability) ? use
ELBE facility gtSummer 2005 Bucharest High
rate multistrip RPC with Glaverbel glass Beam
test at GSI Spring 2005 Bucharest, ITEP,
HD Simulations - Test of various
scenarios min. 12 month!

Conclusion
TOF system for CBM well under way st ? 80 ps
system resolution not impossible, but really hard
work! Parameter space for RPCs still wide open,
explore all possibilities.
