Revision as of 09:34, 13 April 2010
- HRS Checks and Calibration
- Momentum scan for BigBite with elastic scattering on LH2 target, Kinematics A 1,2,3,4,5. Kin. 1,2,3 (1 pass) are not sure due to Qweak.
- Full acceptance calibration for BigBite with Carbon and Deuteron. Kinematics B1 , 2 and C1.
- Fix the matrix elements for BigBite.
- Calibration run for Neutron Array. Neutron array at 50 deg and 15m from the target without lead wall. Elastic scattering of electrons from LH2. Scattered protons detected with HAND. Kinematics D1.
- Calibration of HAND HV, thresholds and efficiency for neutron detection
. Exclusive scattering from Deuteron at X<1. Protons are detected with the LEFT HRS and electrons with the RIGHT HRS (pay attention to polarity switch). Neutrons are detected with HAND in two Kinematics E1 and E2.
