Abstract
The present embodiments relate to lowering the widening of a radiation beam, for example, using a chamber arranged between a beam output and an object to be irradiated. The chamber is filled with a gas or a gas mixture, the average atomic number of which is smaller than that of air, and the volume expansion of which is changeable. The advantage here is that a widening of a radiation beam caused by multiple scattering is reduced.
