- Summary
- A system for measuring the amount of beam-charge loss in a linear-accelerator structure has been developed that uses a pair of beam-current transformers, otherwise used to monitor the linac beam current. This system is necessary to enable the Ground Test Accelerator (GTA) fast-protect system to shut off the accelerated beam in the event of a beam loss that would deposit sufficient energy to damage the accelerator structure. The present GTA accelerator consists of a 2.5-MeV, H{sup −} RFQ, an intermediate matching section (IMS) and a single DTL cavity with an output energy of 3.2-MeV and transmitted current of 35 mA. Based on the RFQ output beam, melting of the copper structures will occur when about 40 nC of beam is deposited in a point loss. For a grazing angle of 30 mrad, up to 640 nC may be tolerated. The beam-current-transmission-loss monitor (BCTLM) system in conjunction with the fast-protect system measures the amount of beam loss between two toroidal beam-current monitors and automatically terminates the macropulse when the integrated loss reaches a predetermined set point. The design and operation of the BCTLM system used in the IMS and DTL section of the accelerator is described.
