| Abstract: | Through theoretical analysis and careful experiments, the origin of X- ray background in the mini- cyclotron was deduced and some methods to suppress it were described. As a result, the background counts have been reduced to 2/5 of the original value, which has greatly improved the detection efficiency, measurement precision and abundance sensitivity of the sensitive mini- cyclotron accelerator mass Spectrometer. |
