Thesis advisor: Lawrence T. Scott / Carbon nanotubes have demonstrated unique characteristics of strength, flexibility, and electrical conductivity. The ultimate goal of this research is to develop a chemical synthesis of a [5,5] carbon nanotube endcap. Three different projects were undertaken in an effort to realize this goal. The first was the production of appreciable quantities of tetrabromocorannulene, a precursor to the endcap. The second was an exploration of a proof of principle C44H14 bowl, and the third was the development of a boronic acid that would add functionality to tetrabromocorannulene, and ultimately a bowl. / Thesis (BS) — Boston College, 2009. / Submitted to: Boston College.

This thesis presents an electrical model of two pairs of interconnects of the ATLAS Phase-1 Upgrade Hadronic Endcap Front End Crate prototype baseplane. Stripline transmission lines of the baseplane are modeled using Keysight Technologies' Electromagnetic Professional's (EMPro) 3D electromagnetic simulation (Finite Element Method) and the connectors are modeled using built-in models in Keysight Technologies' Advanced Design System (ADS). The model is compared in both the time and frequency domain to measured Time Domain Reflectometer (TDR) traces and S-parameters. The S-parameters of the model are found to be within 5% of the measured S-parameters for transmission and reflection, and range from 25% below to 100% above for forward and backward crosstalk. To make comparisons with measurements, the cables used to connect the prototype HEC baseplane to the measurement system had to be included in the model. Plots of the S-parameters of a model without these cables are presented for one pair of interconnects for which the crosstalk is expected to be the higher than most other interconnects of the baseplane. / Graduate / 0605 / 0798 / rdporter@uvic.ca
