Description
A detailed FLUKA study of the RHIC proton beam dump and its downstream superconducting magnets is presented, motivated by future Electron-Ion Collider operation. A full geometry model was developed to quantify nominal power deposition on the superconducting coils. An actual accidental event, in which a slightly under-kicked beam triggered a quench on the downstream magnets, was also reproduced. The measured quench locations and loss signatures were compared with the simulated energy-density distribution to benchmark the model and validate the underlying physics assumptions. By analyzing both nominal and accidental conditions, quench-relevant limits were derived and the capability of the existing dump to safely absorb up to three times the stored beam energy expected for the EIC was assessed. The results provide physics-based confirmation of the dump’s operational margin and inform future machine-protection strategies.
