Abstract

The CLEAR user facility at CERN allows users to receive a beam with energy up to 200 MeV, allowing flexibility in intensity, beam size and bunch structures. Separate from the main CERN accelerator complex, it is capable of hosting numerous experiments and catering to a broad array of needs with rapid installations at 2 test stands on the beamline.

The CLEAR beam is characteristically Gaussian when optimised for transport and a small transverse beam size. It would be highly desirable for many applications but particularly those of a medical nature, to be able to provide a ‘flat’ beam with a uniform intensity distribution over a significant component of its transverse component.

Over the CLEAR winter shutdown, the operators installed a dual-scattering system in the CLEAR beamline to provide this. It was placed several metres upstream of the beamline end to reduce X-ray contamination in the flattened beam and increase total transmission of the beam. Studies on the flattened beam composition in terms of structure and dose were carried out, also utilising a dipole directly upstream of the in-air test stand to separate the electron and X-ray beams for analysis.
