In this talk I will present developments and potential upgrades for TRIUMF's ARIEL and ISAC facilities from an accelerator physicist's point of view. I will start my talk with ongoing projects on ISAC, i.e increase beam time through model based beam tuning and reaching higher charge states with two frequency heating of the charge state booster. I will then continue with potential future...
The Antihydrogen Laser Physics Apparatus (ALPHA) is based at the European Organization for Nuclear Research (CERN). Using low energy antiprotons we produce, trap, and study the bound state of an antiproton and positron, antihydrogen [1]. Given the long history of atomic physics experiments with hydrogen, experiments with antihydrogen offer some of the most precise tests of quantum...
A temperature ($T$)- dependent universal decay law (UDL) of cluster decay is investigated by fitting the half-lives calculated within the $T$-dependent Double Folding model (DFM), in which the temperature dependence of the effective potential is introduced through the charge and matter density distributions of the interacting nuclei, and the half-lives are calculated within a preformed cluster...
The goal of our project is to determine the radiation of photons emitted in a nuclear beta decay including the effect of the interaction with the parent nucleus. In this talk, I will explain in an accessible way Schwinger's proper-time method and illustrate how it determines the electron's Green Function. As one application, I will describe the electron's anomalous magnetic moment (g-2).
The proposed nEXO experiment is searching for neutrinoless double beta decay (0$\nu\beta \beta$) in $^{136}$Xe in a five tonne liquid Xe time-projection chamber (TPC). The addition of Barium tagging may allow for the positive identification of a candidate 0$\nu\beta \beta$ event as a true $\beta \beta$ decay, by extracting and identifying the daughter Ba ion. The nEXO collaboration is pursuing...
Many particle detectors house their liquid scintillators in an acrylic vessel. The acrylic may be coated by a wavelength shifter in situations where the scintillation light is outside the range of the photodetectors. We have investigated the low-temperature properties of pyrene as an alternative to 1,1,4,4-tetraphenyl-1,3-butadiene (TPB) as pyrene has a much longer fluorescence time which...
A test-bench is created that injects digital pulses that emulate ATLAS Liquid Argon (LAr) Front End Board electronic signal pulses in order to test prototypes. The prototypes are for new electronics for an upgrade to the CERN Large Hadron Collider that increases the rate of proton-proton collisions by an order of magnitude. This High-Luminosity Large Hadron Collider requires a completely new...
The Light-only Liquid Xenon (LoLX) experiment is designed to study the properties of light emission and transport in liquid xenon (LXe) using silicon photomultipliers (SiPMs). In addition, we also plan to perform long-term stability studies of the SiPMs in LXe. Another important goal of the LoLX experiment is to characterize and utilize the differences in the timing of Cherenkov and...
The Beam Lifetime 3 (BL3) experiment at the National Institute of Standards and Technology, USA, aims to improve the precision of neutron lifetime measurements and we hopefully resolve the inconsistency by improving the precision. In the BL3 experiment, a Geant4 based simulation has been used to model, develop, and optimize the experimental setup. The physics list, which is used to simulate...
The Electron-Ion Collider (EIC) is a cutting-edge accelerator experiment proposed to study the origin of mass and the nature of the ''glue'' that binds the building blocks of the visible matter in the universe. The proposed experiment will be realized at Brookhaven National Laboratory approximately 10 years from now, with the detector design and R&D currently ongoing. Notably, EIC can be one...
