Description
The 4 Sector Faraday Cup was developed for positioning of a charged particle beams.
The particle beam current can be measured on a central electrode of a certain diameter as
well as on four segments surrounding the central electrode indicating the beam size and position
in relation to the beamline center. Thus, a broad, off-axis incoming beam can step-by-step
be focused and deflected in the right direction. Hardware for charged particle current measurement
as well as a read-out and display software are optionally available for this device.
Each sensitive segment of the 4 Sector Faraday Cup is electrically insulated inside the cup housing
and has to be connected to an electrical vacuum feedthrough by a Kapton insulated wire.
The cup housing itself can also be mounted onto an electrically insulating holder in case
the current on the housing is supposed to be recorded.
Furthermore, the cup setup includes a suppressor electrode to compensate secondary
electron emission from the cup surfaces.
The cup is made exclusively from materials suitable for ultra high vacuum conditions
down to 1e-10 mbar.
