Nimrod (National Institute Machine Radiating on Downs, "the Mighty Hunter"

Nimrod Nimrod (; ; arc, ܢܡܪܘܕ; ar, نُمْرُود, Numrūd) is a biblical figure mentioned in the Book of Genesis and Books of Chronicles. The son of Cush and therefore a great-grandson of Noah, Nimrod was described as a king in the land of ...

between 1964 and 1978. Nimrod delivered its last particles at 17:00 hrs on 6 June 1978. Although roughly contemporary with the CERN PS its conservative design used the "weak focussing" principle instead of the much more cost-effective "strong-focussing" technique, which would have enabled a machine of the same cost to reach much higher energies. The design and construction of Nimrod was carried out at a capital cost of approximately £11 million. It was used for studies of

and sub-nuclear phenomena. Nimrod was dismantled and the space it occupied reused for the synchrotron of the ISIS neutron source.

Magnet power supply

The magnet power supply included 2 motor-alternator-flywheel sets. Each drive motor was 5,000 HP. Each flywheel was 30 tonnes. Each alternator was 60 MVA 12.8kV. Magnet currents would pulse at 10,550 A.Status report on Nimrod ...
