“…Large diameter hemispheric PMTs have been used extensively in many recent neutrino experiments including Superkamiokande [1], Kamland [2], SNO [3], MiniBoone [4], Icecube [5], and Chooz [6]. Ongoing experiments at Double-Chooz [7], DayaBay [8], and Reno [9], all aiming at precision measurements of the yet unknown neutrino mixing angle θ 13 using neutrinos from nuclear reactors, also utilize 8-inch or 10-inch diameter hemispheric PMTs for neutrino detection.…”

With the increasingly common use of large area PMTs (photomultiplier tubes) for nuclear and particle physics experiments, information on the position dependent magnetic field effects across the PMT's photocathode is important to effectively analyze and understand data collected from PMTs. Using an automated twodimensional scanner, we have measured the PMT response to an external magnetic field as a function of the cathode position impinged by a collimated light source. This study shows a clear dependence on the cathode position in both collection efficiency and gain of the PMT in the presence of a magnetic field. In particular, a pronounced valley in the collection efficiency is observed for certain locations of the cathode when the magnetic field is transverse to the PMT axis. The pattern of the position dependence is presented for several different magnitudes and orientations of the magnetic field relative to the PMT.

“…Several studies have already been reported in the literature on the overall response of the PMT to magnetic field when light is shined uniformly over the surface of the photo-cathode [5,11,10]. However, the dependence of the PMT response as a function of the cathode position in the presence of a magnetic field has not yet been reported.…”
