Kimball Physics designs
and manufactures two types of particle detectors: Faraday cups which
collect charged particles for current measurement, and Phosphor
screens which emit light when bombarded by charged particles for
visual real-time observation.
The basic Faraday cups
are stand alone units with no moving parts and are intended to be mounted
in the vacuum system. A number of different types of mechanically or
pneumatically actuated Faraday cups are available; most of these mount
directly on the housing of electron guns, for direct sampling of the
beam. Faraday cup options include: a phosphor screen around entrance
aperture, user-changeable apertures, energy analyzing grids, biased
cups
(collector cup floated away from ground), water cooling, or
an array of cups.
Phosphor
Screens are made of high luminosity P-22 phosphor (ZnS:Ag). The
screens are sensitive to electrons starting at approximately
500eV with a threshold of 1x120-7 A/cm2. UHV screens and Rugged
screens are available.
For part numbers and prices see the
Detectors Part Number Tables.
