Bremsstrahlung endpoint energy monitoring by super(115)In activation detector

Bremsstrahlung endpoint energy monitoring by super(115)In activation detector

It is shown that ratio of super(116m)In and super(115m)In activities, simultaneously produced by neutron capture and photoexcitation of super(115)In, could be very sensitive index for control of the end-point energy of therapy accelerator X-ray beams. The presented method can be used from 7 MeV wher...

Zusammenfassung:It is shown that ratio of super(116m)In and super(115m)In activities, simultaneously produced by neutron capture and photoexcitation of super(115)In, could be very sensitive index for control of the end-point energy of therapy accelerator X-ray beams. The presented method can be used from 7 MeV where begins production of photoneutrons.
