J. Gustafsson et al., K130 BEAM CURRENT MEASUREMENT SYSTEM, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 342(2-3), 1994, pp. 552-557
A measurement system for very low currents, developed to be used in th
e K130 cyclotron at University of Jyvaskyla, is described. The beam in
tensity measurement is implemented with a current preamplifier and sig
nal multiplexor. The measurement is controlled and visualised with a c
ommercial data acquisition card integrated in a PC.
