Drift-pots for small angle elastic scattering at the fermilab collider

Abstract In order to measure the small angle p - p scattering at the Fermilab Tevatron collider we developed very small drift chambers integrated with thin-wall roman pots. We named them drift-pots . The drift-pots are active 100 μm from the vacuum of the beam with an expected resolution of 60 μm in the drift direction and 250 μm in charge division. They are radiation resistant detectors intrinsically insensitive to the beam pickup pulses and their multiple hit readout capability will allow us to push them into the beam halo where p - p Coulomb elastic scattering dominates. For our application, we belive the drift-pots, are superior to state of the art silicon detectors.
