Method for the stress calibration of a beam buncher

At the National Accelerator Centre a beam buncher is used on the beam line between the injector cyclotron and the open sector cycletron to change the length of the beam bunchers to such an extent that it has a minimum length distribution at the open sector cyclotron. The stress applied to the beam buncher can not be measured directly. To study the exact effect of the beam buncher on the beam the exact stress on the beam buncher is necessary. An indirect method to measure the beam buncher stress is looked at as well as the extent to which the beam is bunched at normal usage of the beam buncher
