SLAC End Station A ILC Experimental Program
The SLAC Linac can deliver damped bunches to End Station A (ESA) with beam parameters for bunch charge, energy spread and bunch length similar to the ILC parameters. A 10Hz beam at 28.5 GeV energy can be delivered to ESA, parasitic with PEP-II operation. We are using this facility to prototype and test key components of the Beam Delivery System (BDS) and Interaction Region (IR). Approximately 5 weeks of beam tests were conducted in each of 2006 and 2007. The next run is tentatively scheduled for April 21 - May 8, 2008. 5 Test beam experiments have been approved and taken data: i) T-474/T-491 for BPM-based energy spectrometer prototype (S. Boogert, Royal Holloway, and M. Hildreth, U. of Notre Dame, and Y. Kolomensky, UC Berkeley, are co-PIs); ii) T-475 for a synchrotron stripe energy spectrometer prototype (E. Torrence, U. of Oregon, is PI), iii) T-480 for collimator wakefield studies (S. Molloy, SLAC, and N. Watson, Birmingham U., are co-PIs), iv) T-487 for bunch length diagnostics with Smith-Purcell radiation (G. Doucas, U. of Oxford, is PI), and v) T-488 for background studies of the IP feedback BPMs (P. Burrows, U. of Oxford, is PI).
