Abstract

MOP010; International audience; Assembly and tests of the SPIRAL2 superconducting linac's cryomodules at CEA/Saclay and IPN/Orsay have now reached cruising speed after having faced a series of problems, among them contamination. 19 cryomodules are composing the whole Linac and IPN Orsay is in charge of the 7 cryomodules B, housing two 88 MHz, beta 0.12 Quarter-Wave Resonators. Threecryomodules have been assembled and successfullytested up to the nominal gradient of 6.5 MV/m for all cavities with also cryogenic losses withinspecifications. Two of them are fully qualified and already delivered to GANIL. The thirdone showed misalignment ofone cavity which could lead to partial disassembly if needed. This paper presents the results of those cryomodules tests as well as the status of the remaining ones.

Abstract

SPIRAL2 is a rare isotope accelerator witch will based for next years at GANIL laboratory in Caen, France.This machine is dedicated for the production of high intensity radioactive beams (E= 40 Mev, I= 5mA). The driver of SPIRAL2 is a Linac, it uses bulk niobium quarter wave superconducting RF cavities cooled with liquid helium. Mainly, the Linac is composed of two types of cryomodules: 12 CryomoduleA with one cavity and 7 CryomoduleB with two cavities respectively for low and high energy section. The Linac cryogenic transfer line is composed of about 19 valves boxes witch provide to cryomodules two types of helium cryogenic lines: The first at T=4.3K to feed the cavities and the second atT=60K for the thermal shield. There frigerator of this cryogenic installation must evacuate a totat heat loss of about 1kW at T=4.3K and 2.5kW at T=60K. After a short introduction of SPIRAL2 project, the cryogenic installation design will be detailed and its different operation modes will be described. The preliminary cryogenic experimental test results of the first cryomoduleB and A at IPN ORSAY will be also presented and interpreted.

Abstract

ACC; International audience; A Superconducting Linac Driver, delivering deuterons with energy up to 40 MeV (5 mA) and heavy ions with energy of 14.5 MeV/u (1 mA ), is proposed for the Spiral-2 radioactive beams facility. For the high energy section of the linac, a superconducting 88 MHz Quarter Wave Resonator (beta 0.12) has been designed and the optimisation of RF and mechanical performances will be presented. Based on the present state-of-art of the Superconducting RF technology, maximum electric surface field of 40 MV/m and magnetic surface field of 80 mT, have been adopted which should allow to reach an accelerating field of 7 MV/m (energy gain 3 MeV per resonator). A first complete prototype is under construction. The high intensity deuteron beam specifications have imposed the design of an original power coupler (maximum power 20 KW). The RF, mechanical, and thermal characteristics will be presented. The design of the cryomodule for this high energy section, integrating two QWR with its associated equipments (couplers, tuners, helium tanks), will be presented.

Abstract

TUPPO008; International audience; Accelerator 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.
