Magnetic shielding is a necessary component of electric dipole moment experiments and other precision measurements. Understanding the details of its behavior can improve the outcome of experiments. We have previously reported (AIP Advances 8, 035303 [2018]) that delayed changes in magnetization cause the magnetic flux density inside a Permalloy (mu-metal) shielded volume to decrease over...

amount of change in the natural background activity with time as a result of any ra-
dioactive releases. It is very important to monitor radioactive substances released to the
environment for proper environmental protection. The aim of this work is to investigate
the concentration of radioactive substance in... -

require application of an electric field, which can work as a spectrometer for
recoiling ions and atomic shake-off electrons on their way to MCP based
detectors in a back-to-back geometry. Such a field, in combination with the
drift distance, separates in time the arrival of recoiling, differently charged
ionized... -

We present a nanoscale low-power all-optical switching approach based on surface-plasmon polaritons (SPPs) by employing the concept behind Mach-Zehnder interferometer (MZI). The capabilities of SPPs to confine energy of electromagnetic waves in the subwavelength scale provide the possibility to design miniaturized all-optical switches. We employ nanoscale plasmonic waveguides in MZI and add a...

For eddy current based inspections of CANDU® reactor fuel channels, material electrical resistivity is an important parameter. For pressure tube (PT) to calandria tube (CT) gap measurements, material resistivity values are required to ensure accurate measurement of the gap. The resistivity used during inspections are assumed to be the same as that of calibration PTs, which are non-heat...

In this work, we experimentally created and characterized a class of qubit-ququart PPT (positive under partial transpose) entangled states using three nuclear spins on a nuclear magnetic resonance (NMR) quantum information processor. Entanglement detection and characterization for systems with a Hilbert space dimension ≥ 2⊗3 are nontrivial since there are states in such systems which are both...

A detailed understanding of the beam physics of accelerators is required to move towards a new beam tuning paradigm that involves automatic tuning of accelerators. A complete end-to-end model is required so that high level tuning algorithms can be applied. Therefore, an end-to-end simulation of the ISAC accelerators, which doesnot exist is now under development. We have established an...

Using a newly commissioned VUV transmissometer at TIUMF, the optical constants of the thin films, including MgF2, LiF2, etc from 120nm to 320nm are evaluated.

The VUV transmissometer is a transmission and reflection evaluation system which is designed to deliver vacuum-ultraviolet (VUV) to ultraviolet (UV) radiation to a target sample and measure the reflectance, transmission or fluorescence...
