Multi-Isotope Geochemical Baseline Study of the Carbon Management Canada Research Institutes CCS Field Research Station (Alberta, Canada), Prior to CO2 Injection

Carbon capture and storage (CCS) is an industrial scale mitigation strategy for reducing anthropogenic CO2 from entering the atmosphere. However, for CCS to be routinely deployed, it is critical that the security of the stored CO2 can be verified and that unplanned migration from a storage site can be identified. A number of geochemical monitoring tools have been developed for this purpose, however, their effectiveness critically depends on robust geochemical baselines being established prior to CO2 injection. Here we present the first multi-well gas and groundwater characterisation of the geochemical baseline at the Carbon Management Canada Research Institutes Field Research Station. We find that all gases exhibit CO2 concentrations that are below 1%, implying that bulk gas monitoring may be an effective first step to identify CO2 migration. However, we also find that predominantly biogenic CH4 (∼90%–99%) is pervasive in both groundwater and gases within the shallow succession, which contain numerous coal seams. Hence, it is probable that any upwardly migrating CO2 could be absorbed onto the coal seams, displacing CH4. Importantly, 4He concentrations in all gas samples lie on a mixing line between the atmosphere and the elevated 4He concentration present in a hydrocarbon well sampled from a reservoir located below the Field Research Station (FRS) implying a diffusive or advective crustal flux of 4He at the site. In contrast, the measured 4He concentrations in shallow groundwaters at the site are much lower and may be explained by gas loss from the system or in situ production generated by radioactive decay of U and Th within the host rocks. Additionally, the injected CO2 is low in He, Ne and Ar concentrations, yet enriched in 84Kr and 132Xe relative to 36Ar, highlighting that inherent noble gas isotopic fingerprints could be effective as a distinct geochemical tracer of injected CO2 at the FRS

Design of a compact all-permanent magnet ECR ion source injector for ReA at the MSU NSCL

The design of a compact all-permanent magnet electron cyclotron resonance (ECR) ion source injector for the ReAccelerator Facility (ReA) at the Michigan State University (MSU) National Superconducting Cyclotron Laboratory (NSCL) is currently being carried out. The ECR ion source injector will complement the electron beam ion trap (EBIT) charge breeder as an off-line stable ion beam injector for the ReA linac. The objective of the ECR ion source injector is to provide continuous-wave beams of heavy ions from hydrogen to masses up to 136Xe within the ReA charge-to-mass ratio (Q/A) operational range from 0.2 to 0.5. The ECR ion source will be mounted on a high-voltage platform that can be adjusted to obtain the required 12 keV/u injection energy into a room temperature radio-frequency quadrupole (RFQ) for further acceleration. The beam line consists of a 30 kV tetrode extraction system, mass analyzing section, and optical matching section for injection into the existing ReA low energy beam transport (LEBT) line. The design of the ECR ion source and the associated beam line are discussed

HIERARCHICAL PREFERENCES AND CONSUMER CHOICE.

This study considers the problem of the consumer in light of work presented by classical economists who discussed consumption. Richer assumptions about the tasks of an individual consumer and technology of consumption activities are used to develop a static model of consumer behavior. This model is extended through the introduction of opponent-process theory to develop a dynamic model which includes habit formation. Particular emphasis is placed in Chapter 2 upon the psychological underpinnings of consumption activities and the allocation of time aspect of these activities. It is assumed that a consumption activity is defined as a production function combining commodity and time inputs to produce satisfaction. Chapter 3 presents the framework over which preferences about different activities are defined. Preference relationships are assumed to be rational, transitive, and constant over time and location. In addition, satiation in a particular consumption activity is assumed to exist and the ranking over satiation states is defined. Chapter 4 deals with the behavior of a time and income constrained consumer who seeks to choose an optimal bundle of commodity and time inputs over the ordered activity set. The solution to this problem is characterized by affordable allocation of resources from the highest ranked down to the lowest ranked activity. Comparative statics results associated with this solution are considered for non-labor income, wage rate, and price changes. It is shown that besides the production substitution effects brought about by changes in the wage rate and in commodity prices, the net effect of changes in economic variables is predominantly at the lower end of the preference ordering. Chapter 5 presents both a psychological version of opponent-process theory and an economic interpretation of this theory which is used to describe habit dynamics. Chapter 6 combines the static consumer problem and the dynamic description of activity productions under habit formation to present an extended problem of a dynamic consumer behavior
