Energy interlock system for a linear accelerator.

摘要

The X-ray interlock system is designed for a linear accelerator having no electron beam bending system. The accelerator emits electron pulses which are directed to a target for generation of X-ray pulses. The interlock system contains an ionization chamber, a discriminator and a switch. The chamber is exposed to the X-ray pulses for measuring their intensity distribution. It com prises a control electrode and a plurality of electrode segments. The discriminator is connected for detecting energy inhomogeneities in the X-ray pulses. The switch which is operated by the discriminator is connected to switch the accelerator on and off. The energy interlock system is addapted to be used with linear accelerators in medical treatment.
