An Underwater Six-Camera Array for Monitoring and Position Measurements in SNO+

• This thesis deals with the creation, calibration and performance of the camera system to be installed in the SNO+ experiment. A system of six cameras in underwater enclosures will be used to monitor the position of the acrylic vessel and its hold-down rope net during the course of the experiment. The system will also be used to triangulate the positions of calibration sources lowered into the detector to an expected accuracy of 1.5 cm at a distance of 9 meters. This is an improvement to the previous 5 cm accuracy given by the rope manipulator system used to lower calibration sources into the detector. This result will not be subject to the same position-dependent systematic effects that dominated the previous system. The procedure of testing and calibrating the cameras before their installation is explained in this thesis.
