We describe the design and operations of a lab scale time projection chamber (TPC) which is being developed to test the novel pixelated charge read out scheme, Q-Pix. The aim is to demonstrate the capability of the Q-Pix readout to reconstruct the particle tracks in ultra high pure (UHP) Argon (Ar) in both gas and liquid phase. The TPC is equipped with an Hamamatsu R8520 photo multiplier tube...
We propose a novel detection scheme that utilizes the piezo-pyroelectric properties of ZnO thin films. The aim is to realize a zero external bias vacuum ultraviolet (VUV) detector that can be used in liquid noble time projection chambers. We present initial results from our measurements that test our hypothesis that stress-induced in ZnO thin films through interface strain engineering can lead...
The SPLENDOR collaboration (Search for Particles of Light dark mattEr with Narrow-gap semiconDuctORs) is using novel narrow-bandgap single-crystal semiconductors as ionization detectors to search for low mass dark matter. We have developed a series of magnetic Zintl phase semiconductors with electronic bandgaps on the order of 1-100 meV, which will allow for sensitivities to fermionic dark...
Oak Ridge National Lab (ORNL)’s Electron-Proton/Ion Collider (ePIC) group works on the production and testing of the ePIC LFHCalorimeter. This calorimeter is longitudinally segmented, containing 62,424 read out channels; it will be located in the forward going direction of ePIC. Each module of the calorimeter consists of 65 layer assemblies, made of 8 scintillator tiles placed over a Silicon...
The axion is a leading dark matter candidate which also addresses the Strong CP problem in the Standard Model, but its detection remains challenging due to its extremely weak predicted electromagnetic signals. Superconducting qubits offer a promising solution. Superconducting Quasiparticle-Amplifying Transmons (SQUATs) are designed to be sensitive to single THz (meV) photons by detecting...
Time Projection Chambers (TPCs) use various chemical species as detection media, depending on the specific application, the required sensitivities, and the types of particles being measured. Xenon is useful but of limited availability, and non-xenon double beta decay TPCs may need to choose unfamiliar, probably toxic, gases. We aim to design and build a cylindrical proportional counter that...
Deep Underground Neutrino Experiment (DUNE) experiment aims to answer several fundamental questions about the universe such as why matter dominates antimatter and whether protons can decay. The four 10k-ton far detector (FD) modules built upon the LArTPC’s superior particle tracking and energy calorimetry capabilities are crucial to fulfill the physics potential. While the Long Baseline...
The scalability of sub-Kelvin superconducting sensors is generally limited by their associated superconducting readout electronics, motivating multiplexing schemes which reduce the system complexity, cost, and thermal load on the refrigerator. Microwave SQUID multiplexing, which naturally has access to ~100x the operation bandwidth of alternative schemes, is a compelling candidate for future...
The CMS detector will upgrade its tracking detector in preparation for the High Luminosity Large Hadron Collider (HL-LHC). The Phase-2 outer tracker layout will consist of 6 barrel layers in the center and 5 endcap layers. These will be composed of two different types of double-sensor modules, capable of reading out hits compatible with charged particles with transverse momentum above 2 GeV...
The construction of modules for the Phase 2 Outer Tracker upgrade is underway. Due to the large number required, there will be many sites participating in this process. In order to facilitate smooth assembly and testing of these modules, a consistent environment is required across all of these sites. The sites will use a burn in box to stress and test the modules that require multiple, cutting...
This work with the Relativistic Nuclear Physics Group at Oak Ridge National Laboratory (ORNL) focuses on testing and characterizing Silicon Photon Multipliers (SiPMs) for the Longitudinal Forward Hadron Calorimeter (LFHCAL).

Ge detectors with heat and charge readouts. We focus on the...
The Outer Tracker (OT) of the CMS experiment provides information about the trajectory of charged particles produced in proton-proton collisions at the LHC. During the High Luminosity LHC (HL-LHC) upgrade, scheduled for the late 2020s, the entire tracker will be replaced with new modules that will interface with the Level-1 Trigger for the first time ever at the LHC. Module production is...
The Barrel Imaging Calorimeter (BIC), a subsystem of the Electron Ion Collider's ePIC detector, is a sampling calorimeter utilizing two technologies: scintillating fibers embedded in lead (Pb/ScFi), interleaved with AstroPix silicon sensors, providing the required energy and position resolutions and particle identification capabilities. A small Pb/ScFi calorimeter prototype, based upon a...
We propose a novel particle detection mechanism that utilizes the ability of nitrogen-vacancy centers (NV) in diamond thin films to investigate nanoscale magnetic phenomena on superconducting thin films. Energy deposited by a particle either directly in the superconductor or in an absorber, causes a thin layer of superconductor on the diamond film, to transition to normal state. The transition...

This poster presents the commissioning and calibration results of the...
