Popis: |
In the PKUAMS injection system upgrade project, we adjusted the ion source parameters to get better Cs focus and the smallest emittance and we also redesigned the sample changing mechanical structure. This provides for a more reliable sample change process. The other improvement is that we have rebuilt injection control system by using an industrial personal computer. It is more stable, reliable and easy to use. With the improvement of sample preparation and optimization of the beam optics, now, PKUAMS has the ability to measure the sample which is less than 100 μgC. |
