    keyword=LHRS Cerenkov changes at new momentum setting

    #20180 is the first LHRS run at the new momentum setting (0.700). We see noticeable changes in the physics replay (as one would hope!) but also in the LHRS Cerenkov. Note more low-energy ADC events and the appearance of a second TDC peak 60 ns after the first TDC peak. (The golden run here is from before the momentum change.)
