Description
The High-Current Faraday Cup is a device for measuring high ion beam currents. The setup contains
a metal back plate which is electrically insulated towards the housing but connected to a water cooling
system by a thermally conductive insulator.
Thus, heating power from an incident ion beam of up to 1.5 kW can be dissipated while measuring
an electrical current. Furthermore,
the Faraday cup features a removable aperture plate as well as a suppressor electrode for suppression of
secondary electrons emitted from the cup surfaces at ion impact.
The Faraday cup is mounted on a pneumatic linear push / pull positioner on a DN 160 CF flange.
The up and down position is indicated by two relay contacts. The standard travel length between both
positions is 100 mm which can be adjusted to the requirements of the customer if necessary.
The cup is suitable for ultra high vacuum conditions down to 1e-10 mbar.
The images given in addition to the rendered picture of the complete system show a detailed view of
the cup as well as a simulated heat distribution at 1 kW incident beam power.
