Calibration methods

Laser Flasks

Laser flasks in the tank emit isotropic light at a fixed wavelength. This is used to check the modeling of the different time components of light in the oil. image of laser light time components

Muon Tracker

Two hodoscope planes trigger muons that enter the tank. If the muon stops in one of 3 scintillation cubes, we know the distance it has travelled, and tag it with the decay michel electron. These cubes can be used to study the energy deposited by muons, as well as angular effects.
