350 Mhz, 200 kW CW, Multiple Beam IOT.

摘要

This program was tasked with developing a 350 MHz, 200 kW multiple beam inductive output tube (MBIOT). The design was finalized during the first year of the program (8/1/08 - 7/31/09), and the drawings and mechanical design were completed during the first months of the second year. The electron guns were ordered in January 2009, with delivery indicated as June 2009. Unfortunately, issues with grid fabrication delayed the delivery of the electron guns. The electron guns were finally received in November 2010, which dramatically delayed assembly of the IOT, All other parts for the tube were received early in 2011. The last parts to arrive were the copper and iron plates comprising the end plate assemblies for the output cavity. Failure ot the vendor to machine these plates to specifications also delayed the assembly. Because of these vendor delays, CCR could not complete the assembly of the MBIOT prior to the end of the Phase II program. CCR is continuing this assembly, and testing is scheduled for spring 2012 at Argonne National Laboratory. This report summarized the design and current status of major subassemblies.
