| Outline of Final Research Achievements |
For realize cancer therapy accelerator which could provide both carbon beam and proton beams, we have studied proton beam production using laser ion source. We had already established high brightness carbon beam production form laser ion source, however proton beam production needed further studies. We employed hydride metal targets. We have tested many material and laser irradiation condition to extract high purity proton beam from hydride metal plasma. Finally we successfully established intense proton beam from zirconium hydride target. We also tested robustness of the target and could measure material consumption rate. Based of the results from the basic experimental work, acceleration test was carried out at an existing user facility at Brookhaven National Laboratory. The performance of proton beam production was demonstrated and verified.
