Radiation device using a beam of charged particles |
摘要 |
A beam of charged particles is guided along a path including a looped section between two rectilinear stretches, each of these stretches being provided with focusing and centering means. A holder insertable into the outgoing stretch, ahead of a collimator, carries a target designed to emit photons upon being struck by incident particles. The target holder is linked with a retracting mechanism which also controls a diaphragm in the looped path section to narrow its aperture when the target is in place. A dose-equalizing filter utilized in the latter instance is movable jointly with the target holder out of the path of the exiting beam.
