Measurement of the mean beam current on particle accelerators (beam stopper)

Material:

Cup and shield: Tantalum
Cup support: Stainless Steel
Cup insulation: Ceramics
Cup shape: Conical
Max. beam power: 600W (uncooled version) / 6kW (cooled version)
Connector: BNC
Max. high voltage: 2500V
UHV-Feedthrough: Air actuated Feedthrough

Principle:

The accelerated particles are stopped in the cup and the caught electric charge is detected as a corresponding electric current. The Faraday-cup can be moved in the beam by means of a compressed air actuated vacuum feedthrough.
