Further modifications have been made to our 5-MV tandem (TAMIA) to optimize its performance for AMS and other ion beam analysis studies. An old HVE-type charging belt has been replaced with a conveyor belt from Siegling. Non-contact charging needles were installed in order to lengthen the lifetime of the new belt. A NEC stabilization system has been installed along with new slit preamplifiers and a current divider circuit to diminish the effect of varying ion current on beam energy stability. Energy stabilization with beams of down to 20 pA current has become possible. On the data acquisition side, the SQL-based system has been further developed to allow more detailed off-line data analysis. Performance of the machine will be outlined and recent results discussed.
