  1. QA Activities in 2009 atJSI : Summary • External (in-air) beam: new in-beam charge normalization setup. Put • in operation, stability check • 2. Nuclear microprobe: • A. tissue mapping. On-off STIM incorporation in quantification • procedure (GUPIXWIN). GEOPIXE purchase, setup. Efficiency configuration of • iGe X-ray detector: completed. Si(Li), elements bellow 2.5 keV: further work, • communication with Chris Ryan. New set of QA samples: Micromatter thin foils. • Accuracy confirmed for both GUPIXWIN approach and GEOPIXE. • B. 3He micro-NRA: D values compared with Garching broad beam NRA data on • a:C:D films. Agreement better than 10 %. • 3. Accelerator: 3He ion source reliability. Installation of new type of Li-exchange. • Ion source stable, long micro-NRA run completed. • 4. TNA projects: Regular scan of standard targets (NIST, bulk pure metals) to • check the stability of chopper normalisation. Conclusion: stable, better than 5%. • 5. Participation in SPIRIT round robin with fixed setups: broad beam RBS/ERDA • with 7Li proposed on TiN films.
