    ACCEL, Bergisch Gladbach
  Since October 2006 an ECR ion source is under operation at SOREQ. The source will be used to generate protons and deuterons in a current range from 0.04 to 5 mA. The paper will present operation results as current, emittance and stability measurements. Further the influence of variables as solenoid fields, RF power and gas flow will be described. A short description of the attached beam transport system and beam diagnostic system will be given as well.

  In beginning of 2007 the installation of the first stage of SARAF has been finalized. The system consists out of an ECR ion source, a low energy beam transport system, a four rod RFQ, a medium energy transport system and a superconducting module housing 6 half resonators and three superconducting solenoids. This injector will be characterized with a diagnostic plate. The installation allows continuous measurement of beam charge, position and phase. The diagnostic plate in addition provides a beam halo monitor, vertical and horizontal slit and wire systems, a slow and a fast faraday cup, which can only be used in pulsed operation. The paper will describe the status of commissioning, including results of the site acceptance test of major components.

  In February 2007 a system consisting out of two 5 cell 500MHz cavities has been delivered to SSRF to accelerate the electrons in their booster ring. The two cavities are controlled by a low level RF system, which forms part of the delivery. The paper will describe the general layout of the booster RF system and the architecture of the low level RF system controlling one amplifier and two cavities. Results of the commissioning phase will be presented and compared with expected and guaranteed values of the system.  
THPMN012 A 0.5 to 50 MeV Electron Linear Accelerator System 2731

    ACCEL, Bergisch Gladbach
  Since 1998 ACCEL delivers turn key accelerator for scientific applications. After three injector systems for synchrotron light sources have been successfully commissioned, ACCEL is currently producing a 5 to 50 MeV system for the German Metrological Institute in Braunschweig. Beside excellent beam energy qualities the accelerator has to operate in a wide energy range, delivering 1 to 100 W average beam power to the target. The paper will give a description of the system layout and related technical parameters. The status of the project and results of the factory acceptance test of some of the major components will be presented as well.
