Description

  • Content Description: Beamstops are required for commissioning and operation of accelerators. The family of beamstops currently being developed for the DOE-sponsored Accelerator Production of Tritium (APT) program is addressed. The operational range encompasses proton energies of 6.7 MeV at the beginning of the RFQ to 1.7 GeV at the target/blanket, and both pulsed and cw operating modes. An additional beamstop was needed on a companion test facility to validate ion injector performance. This first of the series of beamstops has been built and operated; the second is under construction and will be operational by mid-1998. Particle stopping distance and duty factor drive the size and heat transfer capacity of these beamstops; the need for low neutron production and activation potential drives the material selection. At energies above 6.7 MeV, the preferred beamstop material is graphite with aluminum the choice for structures and helium the choice for coolant. Boronated water is the preferred shielding below 70 MeV, but is less suitable at higher energies because of the creation of Be-7. The evolution of the low-energy demonstration accelerator (LEDA) to 20 MeV and remaining APT beamstops are presented with performance ramifications and the status of the hardware and testing.
