keyword=putting in Pb/D tgt 1
midnight -- we put in Pb/D tgt 1 (which has never seen beam)
Confirmed BDS position matched expectation to within 4 units.
laser 65, slit 15
L-HRS rate = 90 kHz
R-HRS rate = 87 kHz
adjust slit to 13.5
L-HRS rate = 1600 Hz
R-HRS rate = 1100 Hz
adjust slit to 14
L-HRS rate = 16 kHz
R-HRS rate = 15 kHz
Start a run
L-HRS 27851. R-HRS run 6920
Not hitting any frame. See fig 1.
Present raster is 23 x 9.5 (MCC) = 6 x 4 (spot++)
Increase the raster to 36.6 x 19 (MCC) = 9.5 x 8 (expected spot)
Do runs 27852 and 6921
We are hitting the frame in Y on both sides.
And it seems like we're hitting in X.
Next: make raster 30 x 15 and scan around in X,Y.
