How do Roman Pot detectors work?

[zylime]

Hello, I have been trying to understand Roman Pot detectors, but I'm afraid I cannot understand what is going on even with diagrams and design specifics. (I have been looking at these: http://tdserver1.fnal.gov/project/workshops/crystal_collimation/talks/Convery.pdf and http://accelconf.web.cern.ch/accelconf/e06/PAPERS/MOPLS013.PDF)

Could anyone explain the physics used in Roman Pots or direct me to a good source for this information?

Here's another description for the Roman Pots used for the TOTEM experiment in the LHC. I don't think there's anything special about the actual detector, which is made of silicon strips. But the characteristic feature, which you must have already read about, is that the "pot" contains a separate vacuum and is designed to be moveable so that it can get in very close to the beam.
