Description
Over the last several decades what was originally a General Ionex Corp. Model 846 high-intensity multi-sample negative ion source has been heavily modified to become what is now the Center for AMS at Lawrence Livermore National Laboratory’s (CAMS/LLNL) general use Cs Sputter Negative Ion Sources. One of these CAMS/LLNL ion sources currently in operation at CAMS is used predominately for natural level 14C measurements using the AMS system based around the CAMS HVEC FN accelerator. In order to optimize the operations of this ion source for such 14C measurements, we have delved into the performance of the ion source under reasonable variation of various source parameters. The results obtain in these studies will be presented and discussed.
