Bremsstrahlung production by microsecond E-beam from thin foil in a mirror trap

Experiments on a microsecond E-beam (1 MV, 50 kA, 60 kJ) interaction with a bremsstrahlung converter are described. A thin foil placed between strong magnetic mirrors is used as a target. Multiple passage of the electrons through the thin foil increase bremsstrahlung yield in the low-energy (<50 keV) range of spectrum. Testing of the suggested converter has been carried out. The effect of oscillating electrons on the microsecond diode operation is discussed. It is found that the target with thickness equal to 0.05 of the mean range absorbes the beam practically totally. The time-resolved measurements of X-ray emission uniformity are also presented.
