SNRC and CEA collaborate to the upgrade of the SARAF accelerator to 5 mA CW 40 MeV deuteron and proton beams (Phase 2). CEA is in charge of the design, construction and commissioning of the superconducting linac (SARAF-LINAC Project). This paper presents to the accelerator community the status at March 2016 of the SARAF-LINAC Project.

SNRC and CEA collaborate to the upgrade of the SARAF accelerator to 5 mA CW 40 MeV deuteron and proton beams (Phase 2). This paper presents the reference design of the SARAF-LINAC Project including a fourvane 176 MHz RFQ, a MEBT and a superconducting linac made of four five-meter cryomodules housing 26 superconducting HWR cavities and 20 superconducting solenoids. The first two identical cryomodules house lowbeta ($\beta$opt = 0.091), 280 mm long (flange to flange), 176 MHz HWR cavities, the two identical last cryomodules house high-beta ($\beta$opt = 0.181), 410 mm long, 176 MHz, HWR cavities. The beam is focused with superconducting solenoids located between cavities housing steering coils. A BPM is placed upstream each solenoid.

CEA is committed to delivering a Medium Energy Beam Transfer line and a superconducting linac (SCL) [1] for SARAF accelerator in order to accelerate 5mA beam of either protons from 1.3 MeV to 35 MeV or deuterons from 2.6 MeV to 40.1 MeV. The SCL consists 4 cryomodules equipped with warm diagnostics. The first two identical cryomodules host 6 half-wave resonator (HWR) low beta cavities (β = 0.091), 176 MHz. As the last two identical welcome 7 HWR high-beta cavities (β = 0.181), 176 MHz. The beam is focused through the superconducting solenoids located between cavities and housing steering coils. A Beam Position Monitor is placed upstream each solenoid. A diagnostic box containing a beam profiler, a bunch length monitor and a vacuum pump will be inserted between 2 consecutive cryomodules. The HWR cavities, the solenoid package, the cryomodules and the warm sections are being designed. These studies will be presented in this contribution.

After a detailed design study phase (2003-2004), the Spiral 2 project at GANIL was officially approved in May 2005. The project group for the construction was launched in July 2005, with the participation of French laboratories (CEA, CNRS), the Regional Council of Basse-Normandie and international partners. The Spiral 2 Driver Accelerator is composed of an injector (protons, deuterons and heavy ions with q/A=1/3), a room temperature RFQ, and a superconducting linac with two beta families of Quarter Wave Resonators. It will deliver high intensity beams for Radioactive Ions production by the ISOL method and stable heavy ions for nuclear and interdisciplinary physics. High intensity neutrons beams will also be delivered for irradiation and time of flight experiments. In this paper we focus on the High Intensity Driver Accelerator design and the results obtained with several major components prototypes.

In December 2001, a 5 kW beam was accelerated for the first time at GANIL. This performance was achieved after the increase of SSC2 dee voltage from 170 kV to 200 kV. Moreover, several technical developments have been done, to improve the operation with high intensity beams, and a new electrostatic deflector is under construction in order to reduce losses and activation at the exit of SSC2. This paper presents an overview of these works and the main results on the last accelerated beams.
