| Research Abstract |
The spatial resolution the Tohoku microbeam formation system achieved 1 micron or less, but spatial resolution of the micron CT was confined to around 5 microns because beam intensity was not enough in the CT experiments. In order to improve beam intensity, energy resolution of the Dynamitron accelerator was improved. Beam currents of 250 pA was achieved with a spatial resolution of 1 micron meter.
Sample stage was improved in order to irradiate cells aimed by 3D-CT measurement. This set-up enabled to irradiate cells after 3D-CT measurement.
