    keyword=Scaler gates setup for the L-HRS

    Following Bob's advice, Vince and I setup the gates for the scalers in the L-HRS. The helicity gates are formed at the BigBite weldment and sent to the L-HRS. These gates are then made AND with the run-gate from the L_HRS trigger supervisor and sent to the scalers.

    Right now we have exactly the same setup as we had during the "transversity" run, except that the target spin state will be always on(no spin-flip during d2n). This gives us an extra set of redundant scaler readout in each spectrometer (as we have four gated scaler).

    On a different note, I restored the EDTM pulse going to L-HRS. It was missing since yesterday. This will be useful during coincidence runs.
