Description
The purpose of the beam cerenkov detectors is to determine the beam particle species. A simple study of these detectors can be found in the link above. A Geant study is in the works to refine the above estimates.

FNAL has two semi-differential cerenkov heads that I up for grabs. I spoke Gordon Koizumi about them ,and below is a picture of one of them. It is the Al cylinder behind the green block. It is about 18" in diameter and about 10 ft long.
Gas System
See the BCKOV gas page for up to date info.

Below is a first attempt at a gas system for the beam cerenkov, and some
of the requirements.

Below are some more pictures of the cerenkov heads in the worm, before being modified for installation.
Calculations
19Apr02 More calculations
have been made for the differential cerenkov heads. A summary can be found
here in doc or pdf formats , and the pressure curves
can be found here. The print of the head will
be posted soon.
8May 2003 Win Baker has made a thorugh calculation of the fluxes and tagging
efficiencies. His note can be found here in pdf format.
Drawings
21 oct 2002 The drawing for the cerenkov head has been scanned. The pdf is here.
Test Stand
Photos of the beam ckov test vessel. Its pretty much done and ready to go. It has 6 RTD temperature elements and fast/slow gas fill and fast/slow vacuum capability. It should gives us an idea if this idea is what we really want. So the sooner we get the APACS modules ordered the better. I'm still working on the programming for the ckov and the gas mixing. This week I need to go over where I want to place the various gas racks with Leon.
