I performed a number of studies relating to position reconstruction for DEAP-3600 with the purpose of investigating some open questions. The studies performed include looking into failure populations for one of the position reconstruction algorithms (TimeFit2) as well as code review for that processor. I also investigated evidence of potential liquid argon flow which may be present within the...
Multiphoton microscopy uses nonlinear light-matter interactions to achieve non-destructive, label-free imaging, and is a rapidly emerging optical imaging technique for investigating biological samples. Nonlinear light is only produced by molecules with specific properties, such as fluorescent or non-centrosymmetric structures, allowing for chemically-selective images to be generated....
DEAP-3600 is a liquid argon (LAr) dark matter detector. Its chief advantage lies in the success of pulse-shape discrimination (PSD) at suppressing electromagnetic backgrounds from scintillation events in the LAr. The pulse-shapes of LAr Scintillation serve as a basis for PSD and are modeled as a convolution of detector effects and LAr scintillation physics, the latter of which consists of the...
I will talk about the work on the process of the commissioning the EXO-100 cryostat for future experiments. It will describe the many issues faced when getting the cryostat to full functionality and how these problems were solved.
Silicon photomultiplier (SiPM) modules appear to be an interesting and inexpensive replacement for conventional photomultipliers, presenting a variety of applications as detectors. One of the difficulties using these units as detectors is having a proper readout system to acquire and process the correct information for the experiment. Thus my task over the last 4 months was to learn, develop,...
