LAD Trigger Set-Up

The LAD experiment will detect electrons in the SHMS and HMS with recoil protons passing through the GEMs and scintillators.

Tentative LAD Trigger Configuration:
SHMS:
HMS:
COIN:

For trigger definitions, See Trigger Documentation: https://hallcweb.jlab.org/DocDB/0010/001028/005/trigger_v3.pdf

LAD Trigger Checkout:
