BEAM PARAMETERS AND CHARACTERIZATION TECHNIQUE

A review of the electrical and optical beam parameters is given. We de scribe our computer controlled, four slit beam characterization techni que called computer controlled beam diagnostic CCBD system. The CCBD s ystem can be operated in beam profile and emittance modes. The data co llection is finished with appearance on the screen of the correspondin g three-dimensional diagram: the current density map of x; x' and y; y ' emittance maps. As a result of software manipulation further beam ch aracteristics like current contours, emittance patterns, emittance as a function of beam fraction etc. can be deduced. The setup consists of four motorized, water cooled slits with variable slit width allowing to handle beams from muA up to hundreds of mA.
