## Description

ISIS, sited at the Rutherford Appleton Laboratory \(RAL\), is the world's most productive pulsed neutron source\. Intense bursts of neutrons are produced at 20mS intervals when a heavy metal target is bombarded by a high-energy \(800 MeV\) proton beam from a synchrotron accelerator releasing neutrons by the process of spallation\. This is for a contract for a replacement for the Accelerator system which uses a thermionic triode valve \(tube\) amplifier which is coming to the end of its production life\. This is required to ensure continued operation of the facility\.
