Arrangement and use of the arrangement to generate individual non-depressed position of the electrons ical vactual

摘要

The object of the invention is a configuration for the production of individual non-problematical vactual ical electrons, which is composed of an electron accelerator, of the at least two accelerator - cavities, and an electronically optically thin scattering target or more electronically optically thin litter target between two accelerator - cavities are positioned.The advantages and improvements compared with the prior art, the production of individual non-problematical vactual ical electrons packets with a defined multiplicity of ≧ 1 in a time window of a few picoseconds length, the reduction of the radiation background arising in the region of the test area by at least three orders of magnitude, the penetration of the detectors to be measured by means of directional mono energy electron beams, the variation of the repetition frequency of the individual electrons packets over six orders of magnitude of hz to mhz and the use of the invention in the test and in the calibration of detectors by means of irradiation with electrons, in the determination of the energy-loss of ions, during penetration of material or as a attoampere current source.
