▼ The first phase of the TRIUMF ultracold advanced neutron source (TUCAN) is operational at TRIUMF in Vancouver, Canada, with the second phase scheduled to be completed in 2020. The first proposed experiment with the source is a neutron electric dipole moment (nEDM) measurement. Preparing the experiment requires building the nEDM experimental cell, containing high voltage, magnetic fields, B₀ and B₁ coils, magnetic shielding to run the Ramsey cycle; a prototype detection system; and commissioning the TUCAN source. This thesis focuses on measurements that characterize the prototype UCN counter, as well as the thermal neutron flux measurement around TUCAN, as part of the source commissioning. The UCN counter is a \ce{^6Li}-doped glass detector, designed for high rates of UCN. The detector efficiency is comparable to the GEM-based Cascade-U detector at the UCN source at the Paul Scherrer Institute. Comparing the \ce{^6Li} detector to simulation gave a neutron efficiency of 99.5 ± 0.5~% with a background contamination of 0.3 ± 0.1~%. The total efficiency of this detector was measured to be 89.7^+1.3_-1.9~%. The thermal neutron measurement used Au and Cd-covered Au foils to measure the thermal and colder neutron flux around TUCAN at different temperatures. This measurement was conducted at TRIUMF during the initial commissioning of neutron production. There were some large discrepancies between the measured data and simulation and also between measurements with the same settings. A number of discrepancies were found to be due to differences between the experimental set up and the model. Modeling graphite, in particular, is limited due to the wide variability of the structure of graphite and is known to vary up to 40% from the measurement depending on structural factors. The largest discrepancy was due to difficulties in steering the proton beam onto the tungsten target. However, none of the simulated effects were large enough to cover the measured results, suggesting there was a systematic effect that was not well-understood. While thermal and colder neutron flux was measured, the amount varied too much from irradiation run to irradiation run to determine the flux with consistency.

▼ The existence of a non-zero neutron electric dipole moment (nEDM) confirms the theoretical models of Physics beyond the Standard Model which provide extra sources of CP violation. Based on Sakharov Criteria, CP violation is one of the main ingredients to create the baryon asymmetry in the universe. The current upper limit of the neutron EDM was found to be 3.0×10^(−26) e·cm, which is below the theoretical models predictions. As a result, there is a worldwide quest to find a finite nEDM. The typical experimental method to measure the nEDM uses the ultracold neutrons (UCN) and employs the Ramsey method of separated oscillatory fields. In this method, the Larmor precession frequency of UCN is measured in the presence of aligned Electric and Magnetic fields orientations. Such precision measurements require high UCN statistics and very stable and homogeneous magnetic fields. The work presented in this thesis is focused on the magnetic field and UCN studies for the future nEDM measurement at TRIUMF. The TUCAN (TRIUMF UltraCold Advanced Neutron source) collaboration’s goal is to measure the nEDM to the sensitivity level of 10^(−27) . For this measurement, the < 1 pT magnetic stability requirement could be met by using magnetic shields with high magnetic permeability (μ) to reduce the external magnetic fields. However, external sources such as ambient temperature fluctuations could give rise to a change in the magnetic properties such as μ. The result of the temperature dependence of μ measurements and related simulations are presented here. These measurements set a limit on the temperature control level for the future nEDM measurement at TRIUMF. The TUCAN collaboration’s goal is to design a next-generation UCN source to increase the UCN statistics and reach the required nEDM sensitivity. In 2016, the vertical UCN source that was previously developed at RCNP was shipped to TRIUMF. In 2017, we significantly improved the control system for data acquisition and conduced the first UCN experiments.The status of the current UCN facility at TRIUMF and the result of the first UCN production tests are presented here.

Le laboratoire TRIUMF se spécialise dans la production de faisceaux d’ions rares radioactifs qui sont fondamentaux en physique nucléaire et de la matière condensée, entre autres. TRIUMF construit présentement un accélérateur linéaire d’électrons supraconducteur de 50 MeV, 10 mA dans le cadre du projet ARIEL. Les électrons accélérés seront utilisés pour produire des faisceaux radioactifs par photo-désintégration. Le faisceau d’électrons est « converti » en photons par le rayonnement de freinage des électrons lorsqu’ils traversent un matériau de Z élevé placé directement devant la cible de production. La cible utilisée initialement sera du 9Be afin de produire du 8Li. Le 9Be est intégré dans un composé de BeO fabriqué à TRIUMF et conçu d’après les spécifications de l’IPN Orsay où les tests préliminaires prendront place pendant la construction d’ARIEL. La puissance déposée dans la cible et la production d’isotopes rares sont calculées avec le code de simulations Monte Carlo FLUKA.

The TRIUMF laboratory in Vancouver B.C. is a world leader in the production of rare radioactive ion beams. Such beams are fundamental in research for nuclear physics, nuclear astrophysics and solid state science among others. TRIUMF is constructing a 50 MeV, 10 mA superconducting electron linac as part of its ARIEL project. The accelerated electrons will be used to produce RIB through photodisintegration. The electron beam is “converted” into photons by braking radiation of the electrons passing through a high Z material placed immediately before the production target. The initial target to be employed is 9Be, used to produce a 8Li beam. The 9Be is imbedded in a BeO compound manufactured at TRIUMF and designed following specifications of IPN Orsay where the preliminary tests will be conducted while ARIEL is being constructed. Both the power deposition and rare isotope production rates were calculated using the Monte Carlo simulation package FLUKA.

▼ The Tokai-to-Kamioka (T2K) experiment is a long baseline neutrino oscillation experiment. An intense muon neutrino (or antineutrino) beam is produced at the Japan Proton Accelerator Research Complex (J-PARC) by protons hitting a graphite target. The neutrinos are measured 280 m from the target, and again 295 km across Japan using the Super-Kamiokande detector. This allows for the study of the neutrino oscillations in four channels: the electron neutrino and antineutrino appearance, and muon neutrino and antineutrino disappearance. In T2K, neutrinos are observed primarily via charged current quasi-elastic scattering (CCQE) interactions, as well as charged current single pion (CC1) production. The pion is free to interact inside and outside the nucleus primarily via absorption and charge exchange processes. Reducing the uncertainties on these cross sections reduces the systematic uncertainties for neutrino oscillation measurements. The Dual Use Experiment at TRIUMF (DUET) was conducted to address this issue. This thesis describes the recent results from DUET: the most precise measurements of absorption and charge exchange cross sections of pion on carbon for the momentum range of 201.6~295.1 MeV/c. These DUET measurements, along with existing pion-nucleus scattering data for different atomic nuclei, are used to improve the cascade model that simulates pion-nucleus scattering in T2K, and to reduce the associated systematic uncertainties. These improvements are used in a Markov Chain Monte Carlo neutrino oscillation analysis of the T2K Run 1-8 data, corresponding to 14.7x10e20 protons-on-target in neutrino mode and 7.6x10e20 in antineutrino mode. As a result, the most precise measurement of the parameters that govern the neutrino oscillation phenomenon is obtained. In particular, the values indicative of no matter-antimatter asymmetry (CP-conservation) are excluded at the 95.4% (2-sigma) level. This constitutes the world-leading constraint for CP-violation in the leptonic sector. Advisors/Committee Members: Bhadra, Sampa (advisor).

▼ Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. The following work comprises two studies, bothof which examine the magnetic properties of transition metals in either powder or thin filmsamples. The first part is dedicated to a series of muon spin rotation and relaxation (muSR)experiments on a LaSrNiReO6, double perovskite, powder sample. In the muSR technique, aspin polarized muon beam is focused onto a powder envelope in low pressure and temperatureconditions. The spins of the implanted muons evolve depending on the intrinsic or externallyapplied magnetic field according to Larmor precession. The measurement is based onthe detection of decay positrons that carry this precession information on their preferreddecay directions. Measurements that were realized in wTF, ZF and LF setups, reveal asecond transition to magnetic order at Tc ≃ 22K, below a transition that was observed at T =261K from magnetic susceptibility measurements. The experimental results point to threemagnetic phases, paramagnetic for T > 261K, dilute ferrimagnetic for 22 < T < 261K and amagnetically ordered state for T < 22K, that may implicate ferro- and antiferromagnetismfrom Ni sublattices and Ni-Re interactions. The second part follows an attempt to produce and characterize ultra thin bilayer filmsfor the observation of interfacial chiral structures and skyrmions. Co/Fe/MgO (100) andW/Ni/Cu (100) bilayers were grown with magnetron sputter deposition in various layerthicknesses and their structure was determined by X-ray reflectometry (XRR). The XRRscans presented a relatively thick-layered Co/Fe/MgO film, while extremely thin and roughW/Ni/Cu bilayers, for the purposes of studying films with broken interfacial inversionsymmetry. This study was concluded with indicative magneto-transport measurements thatalso point to the reconfiguration of the growth procedure.
