complete full brem program at 2.5GeV |
collect up to 2.4M evts combining with owl shift runs - same CU configuration |

S2+S4+NOSh+C1+C2 |

increase statistics for tagged photons |
with same CU configuration, change trigger |

1 GeV photon tagged |
magnet on at scaled current (240A); collect runs of 25K evts each |

S2+NOSh+C1+C2+Sback |
10K |
test to redefine full-brem photon trigger to maximize efficiency |
add Sback after tagger and in trigger, take data with no AD |

test to get full-brem+AD |
read sync AD but full-brem trigger; test data readout rate and synchronization |
