| 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.

| THPWO006 | Beam Commissioning of the Linear IFMIF Prototype Accelerator Injector: Measurements and Simulations | 3767 |

The EVEDA (Engineering Validation and Engineering Design Activities) phase of the IFMIF (International Fusion Materials Irradiation Facility) project consists in building, testing and operating, in Japan, a 125 mA/9 MeV deuteron accelerator, called LIPAc, which has been developed in Europe. The 140 mA cw D+ beam that has to be delivered by the LIPAc injector is produced by a 2.45 GHz ECR ion source based on the SILHI design. The low energy beam transfer line (LEBT) relies on a dual solenoid focusing system to transport the beam and to match it into the RFQ*. The beam line is equipped by several diagnostics: intensity measurement, emittance measurement unit, profilers and beam proportion analysis. During the LIPAc injector beam commissioning performed in CEA-Saclay, the deuteron beam intensity transported at the end of the LEBT reached an unprecedented value of 140 mA at 100 keV. In this paper, the results obtained during the commissioning are presented. In particular, beam emittance measurements as a function of duty cycle, extracted current from the ion source and solenoid tunings are exposed. The experimental results are discussed and compared to beam dynamics simulations.

|
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. | ||
