Abstract
ION and electron beam currents are normally measured in terms of either a collected current or the beam power dissipated in a calorimeter. Direct-current collection is complicated by secondary emission at the collector surface, and calorimeters are difficult to use when the beam power is low. For both methods the beam must be interrupted in order to measure the current. The technique described here avoids these disadvantages by measuring the magnetic field associated with the particle beam.
