Just a fast guess of numbers:
Disc DIRC
The numbers are extracted from a calculation looking only at the optical region. The calculations include
dispersion effects but no correction was applied yet. Thus we may expect to become better.
- angles: 5/10 - 22deg
- pion-kaon identification < 2 GeV/c
- kaon-proton < 4 GeV/c
- thickness 10-15mm + container =~ 20 X0
Some preliminary simulation results obtained from Roland Schmidt in Giessen can be found
at
the home page of Bjoern Seitz , follow the link to Disc DIRC.
Forward RICH
Here we just assume the design as in the HERMES RICH. (see also
NIM A553)
- angles: 0-5/10deg
- pions: 0.5 - 16 GeV/c
- kaons: 2 - 16 GeV/c
- protons: 2 - 20 GeV/c
- thickness 1.2m =~ 0.11 X0
