Intstructions: Below 0.450 turn ON the regulation for left Q2 and proceed as normal.
Above 0.450 turn the regulation OFF for left Q2 and adjust the current in left Q2 to get the desired Hall Probe field. 0.1 Amp steps is good enough. See http://www.jlab.org/~lerose/instructions/CSR_magnets_inst.htm for instructions re field setting parameters. There's a link there to a simple tool to calculate the fields for a given momentum setting (note the sign convention) The next several field settings are summarized below. momentum Field -0.62267 0.14172 -0.508557 0.13214 -0.541292 0.12321 -0.504683 0.11489 -0.470550 0.10713
