Development of event-display and general calibration software tools for use in Jefferson Lab's Hall A.

Abstract

This thesis documents the development of an Event Display for use in the BigBite calorimeter in the Super BigBite (SBS) ecosystem of detectors in Jefferson Lab’s Hall A. The development of a functional Event Display also necessitated the development of ancillary tools, namely a new Pedestal-Identifiction and Subtraction tool, as a method to Gain-Match the Photomultiplier Tubes of the BigBite calorimeter by altering the High-Voltages applied to each PMT. All tools created in this project are generalizable and can thus potentially be applied to other detectors within the SBS ecosystem, as well as possibly other detectors within the JLab facility. The Event Display is created to aid in visualization of data, as well as providing another interface for JLab researchers to detect potential issues in the functioning of the BigBite calorimeter. The ancillary tools generated to aid in the development of the Event Display are useful not only for the development and functioning of the Event Display, but are also necessary for proper data collection and analysis.
