ABSTRACT
There are numerous applications of ion beams in the fields of science and technology including the industrial production development and the applied scientific research. In principle one has to distinguish between destructive and nondestructive measuring techniques. The Faraday cup is the most widely used destructive diagnostic element and the beam current transformer represents a nondestructive device. A Faraday cup collects the ions of an ion beam in an electrically insulated cup, and the charge is measured using a calibrated resistor in an appropriate electronic circuit. There are more parameters for the description of particle beams. The beam current may be determined indirectly by a calorimetric measurement of the beam power and the deposited energy. The design of a calorimetric system for beam diagnosis depends very much on the beam parameters and the requirements on the response time of the device.
