Construction
- Target date to finish construction - 11/02/2011 (Wed)
- Drive from IU to JLab for installation - 11/03/2011 (Thur)~
Beam Rates
- The difference between the two figures seems to stem from the scintillating fibres having
directional dependence on the incoming electrons. Without any veto on the incoming electron direction, it seems we will be saturated with scattered electrons.
- Also note that these measurements were done near the end of the beam, where there is
lots of scattering as the main beam exits the vacuum.
