Abstract:
This note describes the procedure used to calibrate the SBD using T:IBEAM as a reference. We give the calibration for Stores 2495, 2502, 2503, 2505 and 2507. The fluctuations between stores are a few tenths of a percent. There is also a measure of the DC beam accumulated at injection which seems to be 1-3 percent of the T:IBEAM. The calibration can be checked on line by comparing T:SBDTWG (the SBD sum of p and pbar) with T:IBEAM. Some information on the statistical noise is given. The statistical fluctuation of SBDPIS / AIS is measured to be about 0.3% and data is also given for SBDPWS / AWS.
