Time Operation Mode of Scintillation Detectors for Measuring the Induced Activity of 12B and 12N at Pulsed Electron Accelerators

Resumo

The possibilities are considered of measuring the induced activity of short-lived radioisotopes ¹²N (T_1/2 ≅ 11.0 ms) and ¹²B (T_1/2 ≅ 20.2 ms) produced in objects of study when they are irradiated with brief beam pulses of an electron accelerator in time intervals between such pulses. To solve the problem, the switching method is applied before and after each beam pulse for power supplies of photoelectron multiplier dividers on the scintillation detectors used to detect particles emitting from these objects at the decay of produced ¹²N and ¹²B.
