Construction of a 700 MHz prototypal cryomodule for the EUROTRANS ads proton linear accelerator

Abstract

TUPPO008International audienceAccelerator Driven system (ADS) are being considered for their potential use in the transmutation of nuclear waste. Such a device typically requires a 600MeV to 1GeV accelerator delivering a high intensity beam. Because of the induced thermal stress to the subcritical core, the high-power proton LINAC will have to fulfill stringent reliability requirements. One working package of the EUROTRANS project is dedicated to the design, realization and tests of a prototypical cryomodule, operating at 2K, for the LINAC high energy section. Elliptical cavities will compose this accelerator section. A full scale cryomodule with a beta 0.47 TRASCO cavity and its cold tunning system will be tested at IPNO, early 2010. Experiment aims to evaluate the cavity performances (Eacc=8.5 MV/m) but above all the whole cryomodule reliability to fulfill ADS stringent requirements
