WIDG Seminar: Will Tyndall, Yale, “Nearfield to Farfield Methods for Drone Beam Mapping”

Extracting cosmological 21 cm emission from the radio foregrounds which dominate requires precision calibration, including sub-percent measurements of the complex instrument beam. 21 cm cosmology experiments are typically driven to be compact transit interferometers with poor point-source sensitivity, and have found it difficult to constrain the beam shape to this precision with sky data alone. A technique that has been developed and demonstrated by multiple groups to address this is to transmit a calibrated RF signal from a drone into the telescope to measure the beam pattern.

WIDG Seminar: Evan Craft, Yale, “Beautiful and Charming Energy Correlators”

Understanding the detailed structure of energy flow within jets, a field known as jet substructure, plays a central role in searches for new physics, and precision studies of QCD. In this talk, I will discuss how reformulating jet susbtructure in terms of correlations of energy flow can be used to provide new insights into hadronization and intrinsic mass effects before confinement. In particular, I will show how energy correlators manifest the long-sought-after “dead-cone” effect of fundamental QCD.

NPA Seminar: Cyndia Yu, Stanford University, “The Microwave SQUID Multiplexer for Cosmic Microwave Background Measurements”

I will present the development and demonstration of the microwave SQUID multiplexer for cosmic microwave background observatories and discuss some of the science enabled by these large-scale focal planes. As CMB experiments become ever more sensitive, devising methods to maximize detector count will become ever more urgent. The microwave SQUID multiplexer (umux) enables multiplexing factors in the 100s or even 1000s by coupling each detector to a unique superconducting microwave resonator.

WIDG Seminar: Glenn Richardson, Yale, “Searching for the Majorana Nature of the Neutrino with nEXO"

One of the most intriguing puzzles in physics is the mechanism by which the neutrino derives its mass. A possible solution is given by a Majorana mechanism wherein the neutrino is its own anti-particle. If this were the case, the neutrino would be the first known fundamental particle to be Majorana, and could provide a pathway for leptogenisis as well as a possible explanation for our matter dominated universe. A simple and direct method to probe for this mass mechanism is by searching for the hypothetical decay process called neutrinoless double beta decay.

NPA Seminar: Andrew Mastbaum, Rutgers University, “Xenon-doped liquid argon TPCs as a neutrinoless double beta decay platform”

Searches for neutrinoless double-beta decay (NLDBD) continue to expand our understanding of the lepton sector, with several promising experimental paths toward increased sensitivity. We have considered the possible reach of a large-scale deep-underground LArTPC experiment doped with NLDBD candidate isotope xenon, and the challenges this approach would entail. In this talk, we will review the essential design requirements, background mitigations, and several open R&D questions relevant to such a detector, and discuss the potential sensitivity.

Introduction to Yale Spinup and Cloud Computing Workshop

Led by Vincent Balbarin, Research Computing Specialist, Wright Lab & YCRC
Public cloud platforms such as AWS, Microsoft Azure, and Google Cloud offer variety, flexibility, scalability, availability and resilience without the need for self-hosted data centers.
Yale Spinup Self-Service provides access to commonly used services hosted in Amazon Web Services and is an ideal environment to learn cloud computing concepts and approaches.

NPA Seminar: Monica Nunes, Fermilab, “Construction of SBND: Short Baseline Near Detector at Fermilab”

The Short-Baseline Near Detector (SBND) will be one of three Liquid Argon Time Projection Chamber (LArTPC) neutrino detectors positioned along the axis of the Booster Neutrino Beam (BNB) at Fermilab, as part of the Short-Baseline Neutrino (SBN) Program. The detector is currently in the construction phase and is anticipated to begin operation in 2023. SBND is characterized by superb imaging capabilities and will record over a million neutrino interactions per year. I will present the steps of the construction of this new detector and the preparation for operation.

NPA Seminar: Veronica Dexheimer, Kent State University, “Probing exotic matter in neutron stars”

The high densities achieved in neutron stars and the high densities and temperatures achieved in neutron-star mergers create ideal testing grounds in which to learn about exotic matter, namely hyperons and deconfined quarks. The presence of exotic matter can strongly affect the interior of neutron stars, but cannot be directly observed. New electromagnetic and gravitational-wave constraints have been slowly constraining the dense QCD equation of state, allowing us to learn important information about the strong interaction.
