Numerical optimization of ion transport in electrospray mass spectrometry
… modeling the ESI process in ion optics software SIMION. Two electrode geometries under consideration for use in these studies are presented to test if current understanding in literature is enough to construct simulations to support informed decision making on instrumentation. These geometries …

The brightness-weight correspondence in adults and infants
… Walker, Bremner, Lunghi, Dolscheid, Barba, & Simion, 2018). The objective of the current thesis was to understand more about the correspondence between brightness and weight by examining the situations in which it is revealed and the age at which it emerges. In doing so, the intention was to …

Cache design exploration in a general purpose massively parallel architecture
Memory model design is a major part of any modern processor architecture. There are many design choices and tradeoffs to be considered, and these often need to be tightly coupled to the processing unit's arcitecure. The increased popularity of massively parallel architectures has motivated …

Biases in Looking Behaviour during Visual Decision Making Tasks
… response. Replicating prior findings (Shimojo, Simion, Shimojo, & Scheier, 2003), just prior to the response we found an increase in the frequency of dwells on the chosen item. In addition, throughout the decision, dwells on the chosen item were longer than dwells on other items. This pattern of …

Development of Ion Mobility Mass Spectrometry Instrumentation to Investigate the Gas-Phase Structures of Protein and Protein Complex Ions
… results and ion trajectories implemented using SIMION were used to describe the separation principles of ions in RF-confining drift cells. Those results show that RF-confining drift cells separate ions similarly to traditional IM devices and that applied RF potentials have minimal effects on the …

Positronium in the AEgIS experiment: study on its emission from nanochanneled samples and design of a new apparatus for Rydberg excitations
… line, was designed and built. COMSOL and SIMION softwares were used for designing a magnetic transport line and an electron optical line, which extracts positrons from the magnetic field and focus them on the nanochanneled Si sample. More, a buncher device, which spatio-temporally …

A High-Resolution Time-of-Flight Spectrometer for Fission Fragments and Ion Beams
… and scattering are deduced. A dedicated SIMION 3D simulation showed that introducing serpentine like wires with pitch distance of 1 mm is capable of providing transparency of more than 90% without significant impact on the time resolution. 4. Since the performance of the MCP detectors is …
