    keyword=HAPPEX run 31554

    Took a short HAPPEX run 31554. THis run has a 100Hz tagger, and a 10kHz pocket pulser to form: T1.or.tagger.or.(10kHz) and GC.or.tagger.or.(10kHz). This way we can check if extra T1 rate can cause a loss from the VETO side.

    PS a quick look at the data show a relative loss of 0.0002. Could this be 10kHz*20ns (pulser width)?
