Water data: bad TPC pads, 3.6 µs and 100 ns problems

Out of the 3972 pads of the HARP TPC, about 9% are 'bad' and not useful for the correct reconstruction of clusters. Bad pads comprise dead pads, noisy pads, and pads with low or undefined amplification. Pads may be bad at one time, but not at another. This memo discusses the sources of inf...

description Out of the 3972 pads of the HARP TPC, about 9% are 'bad' and not useful for the correct reconstruction of clusters. Bad pads comprise dead pads, noisy pads, and pads with low or undefined amplification. Pads may be bad at one time, but not at another. This memo discusses the sources of information which were used to declare a pad 'bad', and gives the list of bad pads for the water data (runs 19146 to 19301). Also, the 3.6 µs and 100 ns problems of the TPC readout are discussed, including the corrective measures which have been taken.
