Abstract
PurposeTo protect accelerator devices from being damaged by high-power beam, a new beam dump system is under design for HIAF-BRing.
MethodBased on the optical characteristics, unwanted particles are safely deflected to a specific internal absorber through a local bump orbit generated by active-discharging magnets, which is achieved by paralleling a bleeder resistor of 600 mΩ to two of dipole magnet power supplies.
ResultsTaking alignment and multipole field errors into account, discarded beam can be dumped within 5 ms with an efficiency of more than 99.8% at any operation stage.
ConclusionThe proposed beam dump solution satisfies the machine protection requirements for BRing and can provide a new idea for similar facilities.
