• Output-Shape Measurements for the Pulsed Radiation with Cerenkov-Light Detection Techniques

抄録

A study of the output-shape for the pulsed radiations was carried out by means of a Cerenkov-light detection. The electron output-shapes of the Betatron were single- or double-peak distributions and varied with electron intensity. For the 10 MV Linac (105 degrees bended beam) x-rays its shapes showed triple-peak distributions and varied with magnetron frequency. The output-shape of the 6 MV Linac (straight beam) x-rays was a rectangular-like wave. And, the observed pulse-width was about 2 micro-second for the all.<BR>The Cerenkov-light detector is easily con s t r acted and measurement can be simply carried out. Therefore, it is seemed that this method is useful for an adjustment of the pulsed radiation output of the therapy machines.
