Commissioning of ELLIE for SNO+

Understand

SNO+ is a neutrinoless double beta decay and low energy neutrino experiment located in Sudbury, Canada.

• To improve our understanding of the detector energy resolution and systematics, calibration systems have been developed to continuously monitor the optical properties of the detector, such as: absorption, re-emission, scattering and timing.
• A part of this in-situ optical calibration system is the Embedded LED/Laser Light Injection Entity (ELLIE).
• It consists of three subsystems: AMELLIE, SMELLIE, TELLIE.
