Development of Liquid Argon Purification System for Neutrino Research
Abstract:
Liquid Argon Time Projection Chambers (LArTPC) are widely used for neutrino detection. The Q-Pix collaboration focuses on improving neutrino event reconstruction through a 3D pixelated readout system, offering lower detection thresholds and improved spatial and energy resolution. To support the development of the Q-Pix technology, our group at Wellesley is constructing a lab-scale LArTPC for prototype testing, which requires a dedicated liquid argon purification system. The purifier contains active copper and molecular sieves, which eliminate oxygen and water, keeping electronegative contaminants at an extremely low level. The associated purity monitor measures the resulting purity of the liquid argon by monitoring the attenuation of the charge signal due to electronegative impurities. My thesis describes the construction of the liquid argon purification system, the implementation of a slow control and monitoring system with an integrated database, and the measurement of impurity concentration to evaluate the purifier’s performance.

Quality assurance of Macro-Pixel Sub-Assemblies (MaPSA) before installation in CMS
2023 U.S. CMS PURSUE internship, 2023 APS CUWiP Poster Presentation
Advisor: Dr. Jennet Dickinson, Fermilab
The High Luminosity upgrade for CERN's LHC will replace CMS silicon tracking detectors
with PS modules featuring the Macro-Pixel Sub-Assembly (MaPSA). I developed database system
for MaPSA quality assurance, enabling performance tracking of each MaPSA's pixel through an
accessible database before installation into the CMS outer tracker.
Development of a Small-Scale Liquid Argon Purification System for Neutrino Research
Science Center Summer Research Program 2024
Advisor: Dr. James Battat, Wellesley College
We developed a small-scale LAr purification system for neutrino detection, using active
copper and molecular sieves to eliminate oxygen and water, ensuring low contaminant levels.
I constructed the apparatus, developed data acquisition software, and ran the regeneration
process to prepare the purifier.
