Abstract: Aerogel and water Čherenkov detectors were employed to tag kaons for a hypernuclear spectroscopic experiment which used the reaction in experimental Hall C at Jefferson Lab (JLab E05-115). Fringe fields from the kaon spectrometer magnet yielded gauss at the photomultiplier tubes for these detectors. These fields, which could not be easily passively shielded, would result in a lowered kaon detection efficiency if not mitigated. A bucking coil was placed on each photomultiplier tube to actively cancel this magnetic field, thus recovering kaon detection efficiency. [Copyright &y& Elsevier] more...
