The SA-CERN Program 1.SA CERN started as a consortium of researchers who had long standing research program with CERN  Modeled along the Australian, Indian and Brazilian programs.  Allows for central point of coordination and resource allocation. 2. Agreement was that iTL would act as a neutral institutional hosts for the SA-CERN program:

27 Grenoble Test Source 2 (GTS2)at iThemba LABS iThemba LABS is in the process of assembling an electron cyclotron resonance ion source (ECRIS GTS2) that was designed by CEA in Grenoble, France, but not manufactured by them, because that division closed down. iThemba LABS bought the design drawings of the source from them and is now in the final stage of assembling the source. This source is the only other source that is based on the same design as the heavy-ion ECRIS used at the Large Hadron Collider (LHC) facility at The European Organization for Nuclear Research (CERN) facility in Europe, and subsequently a collaboration agreement was proposed by CERN. A Letter of Intent was signed between iThemba LABS and CERN to outline the terms and conditions of the collaboration agreement, which involves the initial commissioning of the GTS2 ECRIS at iThemba LABS, followed by the study of specific heavy-ion beams as requested by the fixed target experiment (NA61) group at CERN. The aim will be to find the optimal source settings and to characterize the source behavior for these specific ion species. Construction is on schedule for completion by the end of 2010.

28 ECRIS – GTS2

29 Charge state Current (micro ampere) The beam currents are shown for the different charge states of a xenon from different sources. The AECR source is from the USA, the GTS source from CEA in France and SERSE and VENUS are super conducting sources from Italy and the USA, respectively.

Letter of Intent between iThemba LABS and CERN and Initial activities to ensure the success of this project The NRF made available R4M which was needed to buy and manufacture the outstanding components of the GTS2 ECRIS. Letter of Intention was signed by both parties on June CERN and iThemba LABS respectively contribute CHF50k and R200k for the execution of the project. Dr Rainer Thomae from iThemba LABS is visiting CERN from 27 July – 10 August 2010 to gain experience in operating the CERN GTS2 ECRIS. Dr Thomae will visit CERN later this year to assist with the operation of the CERN GTS2 ECRIS when it will be use to produce heavy ions for the CERN accelerators. Dr Detlef Kuchler from CERN will visit iThemba LABS by the end of 2010 to help iThemba LABS with the commissioning of the GTS2 source.
