FIRST RESULTS FROM THE ISIS RFQ TEST STAND

The ISIS RFQ is a 665 keV, 202.5 MHz 4-rod RFQ designed in collaboration between RAL and Frankfurt University. It is intended to replace the Cockcroft-Walton pre-injector currently in use on the ISIS spallation neutron source at the Rutherford Appleton Laboratory. A test stand has been constructed to allow for an extended period of offline test and measurement before final installation. This paper presents the results of those experiments completed on the test stand so far.
