Calibration of the Super-Kamiokande Detector

Understand

Procedures and results on hardware level detector calibration in Super-Kamiokande (SK) are presented in this paper.

• In particular, we report improvements made in our calibration methods for the experimental phase IV in which new readout electronics have been operating since 2008.
• The topics are separated into two parts.
• The first part describes the determination of constants needed to interpret the digitized output of our electronics so that we can obtain physical numbers such as photon counts and their arrival times for each photomultiplier tube (PMT).
