Aiming at the problem of composite anomaly detection and health monitoring, the improved twin support vector machine(TWSVM) with kernel principle component analysis(KPCA) is applied to aircraft composite health monitoring. Firstly, model of uniplanar multi-electrodes was partitioned into equal area units with FEM so that data was acquired enough. Secondly, KPCA was used to select the dimension of...
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...
Heavy ion irradiation facility dedicated for single event effect ground simulation testing has been developed on Beijing HI-13 tandem accelerator. Two dimensional magnetic scanning method was used to produce a large and uniformly distributed beam. Non uniformity of beam distribution is less than 10% over an area of 100mm×100mm. In order to enhance the output energy of tandem accelerator highly stripped...
