- Note, all non-JLab numbers must be dialed with an area code. When calling from a counting-house landline, dial "9" first.
- To call JLab phones from outside the lab, all 4-digit numbers must be preceded by 757-269

CLAS12 Engineering Run, Fall 2017
Beam energy 10.6 GeV (5 pass)
Torus : +3200 A (85% field), Solenoid: 2416 A (100% field), full target;
Important: Document all your work in the logbook!
Remember to fill in the run list at the beginning and end of each run (clas12run@gmail.com can fill the run list)
RC: Daniel S. Carman
- (757) 575-7540
- 9 575 7540 from Counting Room
- carman@jlab.org
PDL: Eugene Pasyuk
- (757) 876-1789
- 9 876-1789 from Counting Room
