| Outline of Final Research Achievements |
We have succeeded in the practical use of a high sensitive beam current meter to measure the DC current of heavy-ion beams non-destructively at high resolution. This current meter uses a high critical temperature (HTc) superconducting quantum interference device (SQUID) which is a very sensitive magnetometer used to detect magnetic fields produced by a brain or a heart. Unlike at other existing facilities, a low vibration, pulse-tube refrigerator cools the HTc fabrications including the SQUID in such a way that the size of the system is reduced and the running costs are lowered greatly.
