Abstract
The new lead/scintillating-fibre calorimeter (''SpaCal'') for the back ward region of the H1 experiment at HERA (DESY) is equipped with fine mesh phototubes which operate in a magnetic field close to 1T, A large sample of these tubes of the types Hamamatsu R5505 and R5506, and Ham amatsu R2490-06, have been tested in fields of up to 1.2 T. We have in vestigated the cathode homogeneity with and without magnetic field, th e gain loss under the influence of the magnetic field? and stability w ith time. For a subsample of tubes, we have performed additional studi es on stability with respect to temperature changes, variation of gain as a function of the magnetic field, high voltage discharges, single photo-electron response, and linearity. We finally summarize the exper ience with these tubes after one year of operation in the experiment. (C) 1998 Elsevier Science B.V. All rights reserved.
