11–20 MeV Alvarez Drift Tube Linac for low energy proton accelerator

Abstract Bhabha Atomic Research Centre is developing Low Energy High Intensity Proton Accelerator (LEHIPA) as a pre-injector for proposed Driven Sub-Critical Reactor Systems (ADSS). Drift Tube Linac one of the two major accelerating structures LEHIPA, other being Radio Frequency Quadrupole (RFQ). Like all particle structures, DTL needs multi-disciplinary expertise design, production, qualification, and installation. This paper describes comprehensive installation ∼ 11–20 MeV section DTL. It details design sub-components which form part RF cavity. Several novel concepts were implemented in course this development. Important among them are DT-DTL alignment, referencing methodology, robust vacuum hermetically sealed DTs. coverage development aspects Alvarez At present, ready beam commissioning.
