Abstract :
The new generation ESA SEU Monitor was used in Beijing HI-13 Tandem accelerator after initial cross-calibration with the proton beams at Paul Scherrer Institu. Heavy ion cross sections obtained at HI-13 were very consistent with those from HIF and RADEF facilities. Beam homogeneity was also verified based on the SEU physical bitmap. In addition, the cross section dependence on ion energy near direct ionization threshold was preliminarily analyzed. An effects of die orientation on heavy ion SEU rate was first discovered. The die design layout may be responsible for this phenomenon.
