run list
He-3 timing is in patch panel 223A16, & energy is 223A17.
High voltage & discriminator settings:
30T: 1450;30 , 30B:1450;30 , 54T: 1500;30 , 54B: 1500;30 , 78T:1500;30 , 78B: 1525;30 , 126T: 1500;30 , 126B: 1500;30 , 150T: 1500;40 , 150B: 1500;40 , 210T: 1500;40 , 210B: 1500;40 , 234T: 1500;30 , 234B: 1500;30 , 258T: 1350;30, 258B: 1450;30 , 306T: 1400;30 , 306B: 1400;30 , 330T: 1450;30 , 330B: 1500;30
Radiator 1.5" Al.
Slits currently at 500 => 19 mm, at 75 =0, at 1000=38 mm, readback number is linear with slit width.
Small aux. scintillators have a CFD threshold of 0.550 V for run 6274 and later.
