Cryogenic thermoacoustics in the SPIRAL2 LINAC

Assembling, Testing and Installing the Spiral2 Superconducting Linac

Assembly and tests of the SPIRAL2 superconducting linac's components are now proceeding smoothly. Cryomodules are being processed in CEA Saclay and IPN Orsay, inter-cryomodules "warm" sections in GANIL. While installation of the accelerators components is going on in the new SPIRAL2 building in Caen, installation of the cryomodules will begin during the last quarter of 2013. The latest results ...

Spiral2 Accelerator Construction Progress

The installation of the SPIRAL2 superconducting accelerator at GANIL is almost started. All the major components have been tested in the various partner laboratories, and the building construction is now well engaged. The management of the interfaces between the process and the buildings is a strategic point in an underground accelerator, with strong space constraints. This paper describes the ...

Status and Challenges of the Spiral2 Facility

SPIRAL2 is a new European Radioactive Ion Beams facility being constructed at the GANIL laboratory (Caen, France). It is based on a High Intensity CW multi-ion Accelerator Driver (Superconducting Linac), delivering beams to a High Power Production system (converter, target, and ion source), producing and post-accelerating Radioactive Ion Beams with intensities never reached before. The major co...

The Lebt Chopper for the Spiral2 Project*

The Spiral2 driver uses a slow chopper situated in the common section of the low energy beam transport line to change the beam intensity, to cut off the beam in case of critical loss and to avoid hitting the wheel structure of rotating targets. The device has to work up to 10 kV, 1 kHz repetition frequency rate and its design is based on standard power circuits, standard vacuum feed-through and...
