Description
For the ESS superconducting linac in Sweden, four compact beam stops were designed instead of bulky beam dumps. The beam stops dump protons either up to 100 MeV or 250 MeV; the most demanding beam modes have an average beam power of 700 or 1100 W, respectively.
The beam stops are water-cooled and moved by pneumatic actuators.
The beam stops were designed at the ESS in Sweden and manufactured by Proactive R&D in Spain. The assembly, acceptance tests and metrology measurements were performed in ISO-5 cleanrooms, before the installations in the particle-free environment next to superconducting cavities of the ESS linac.
This contribution summarizes the assembly, testing and operational experience.
