摘要:
A simple circuit is described which integrates approximately beam currents of 10−14amp. or larger. It consists of a d.c. amplifier, which converts the current into a voltage signal, and a voltage integrator circuit. Integration is approximate primarily because of slow circuit response to fluctuations; under usual conditions of high voltage accelerator work, one can expect integration accuracy of about one to five percent.
