| THPWO003 | Final Design of the IFMIF Injector at CEA/Saclay | 3758 |
|
||
|
The IFMIF accelerator dedicated to high neutron flux production for material studies is now entering in a new phase. For this irradiation tool, IRFU institute from CEA/Saclay is in charge of the design, construction and characterization of the Injector. The high intensity deuteron beam is produced by an ECR source located on a 100 kV platform. The 2 m long LEBT, based on 2 solenoids, is ended by a cone installed at the entrance of the RFQ. Specific diagnostics (cameras, Allison type emittance scanner, fiberscope) have been installed for the beam characterization. During the last weeks, after Injector conditioning, more than 100 mA of deuteron beams have been characterized after the RFQ entrance cone in pulsed and continuous mode*. The shipment of the Injector towards the Rokkasho site in Japan (where it will be reinstalled) is foreseen at the beginning of 2013. This paper will focus on the final design used during the beam characterization experiments at Saclay.

| THPWO005 | Commissioning of the Spiral2 Deuteron Injector | 3764 |
|
||
| The SPIRAL-2 superconducting linac driver, which aims at delivering 5 mA, 40 MeV deuterons and up to 1 mA, 14.5 A.MeV q/A=1/3 heavy ions, has now entered its construction phase in GANIL (Caen, France). The linac is composed of two injectors feeding one single RFQ, followed by a superconducting section based on 88 MHz independently-phased quarter-wave cavities with room temperature focusing elements. The protons/deuteron injector have been fully built and commissioned at CEA Saclay in 2012, before moving and final installation at GANIL in 2013. Beam emittances have been measured at different positions of the LEBT and especially at the RFQ injection point. The space-charge beam compensation has been also carefully studied. This paper describes all the results obtained during this commissioning. | ||
| THPWO008 | Status of the 70 MeV FAIR Proton Injector | 3773 |
|

|
Funding: BMBF The FAIR project requires a dedicated proton injector for the creation of high intensity secondary antiproton beams. This machine will be the first high intensity linear accelerator based on CH-DTL. The status of the project, with particular emphasis on the construction of the first RF prototype is presented. |

| THPWO009 | Beam Dynamics Error and Loss Investigation of the FAIR Proton Injector | 3776 |
|
||
| The FAIR Proton Linac is a 70mA, 70 MeV. 325 MHz linear accelerator based on CH cavities. The focusing scheme is provided by an asynchronous KONUS lattice period. Random misalignment and rotation errors of the quadrupoles, together with phase and RF settings of the power source plays a major role in beam losses. Those effects are investigated and the beam dynamics results, including several source of errors, are presented and discussed. | ||
