1.3 GHz RF Power Source including SNS Modulator
L-band test stand in End station B, a ILC test facility at SLAC
The ILC-group at SLAC is planning an L-band RF test stand in End station B. This test stand will be used to conduct R&D related to the ILC project.
The facility will consist in a first stage out of a high power Modulator driving an L-band long pulse klystron. The RF power will be routed into the NLCTA enclosure using standard waveguide. The experimental program will take place in a dedicated area in the NLCTA beam line. We hope to install and commission the components during the current calendar year and start ‘routine’ operation from the beginning of 2006.
We envisage adding a second modulator and klystron (10 MW) at a later stage (2007).
Modulator:
On loan from SNS (135 kV, 95 A, 2 ms pulse length, rep. rate 5 Hz)

Klystron:
Commercial Klystron from Thales (TH 2104C),
1.3 GHz, 5 MW, 2 ms pulse length, 125 kV
Experimental Program:
We plan to test high power normal conducting accelerating structures needed for the positron and electron injectors of ILC. The test will comprise RF processing and beam tests using a single bunch. Furthermore L-band components needed for the ILC such as couplers and high power waveguide components will be qualified and tested in this facility.
The facility will be focusing on testing and evaluation of ILC baseline klystrons and modulators as well as new concepts in this areas like a sheet beam klystron and a Marx-Generator currently studied at SLAC.
Status:
We are currently purchasing long lead time items like the Klystron and the Circulator. The End Station is being prepared to receive the Modulator and the layout of the high power wave guide system started (get an idea on a preliminary layout). The design of the LLRF system has started as well.
The overall schedule of the project can be found here:
We have a weekly meeting for this project on Mondays at 11:00 am.
Budget:
We plan to spend about 600k$ in FY05 for this facility and we expect to have a similar amount available in FY06.
