| Abstract: | Storage rings offer the possibility of realizing a current by counting the electrons or ions per second passing through a toroidal SQUID current comparator. This technique offers the possibility of accurately measuring the quantity h/e2 and providing a stringent test of the quantum Hall effect. |
