In order to calibrate the Super-Kamiokande experiment for solar neutrino me
asurements, a linear accelerator (LINAC) for electrons was installed at the
detector. LINAC data were taken at various positions in the detector volum
e, tracking the detector response in the variables relevant to solar neutri
no analysis. In particular, the absolute energy scale is now known with les
s than 1% uncertainty. (C) 1999 Elsevier Science B.V. All rights reserved.
