ABSTRACT:

This thesis outlines the preliminary construction of an improved experimental apparatus dedicated to the investigation of ultra-cold fermions. Our research aims to discover the new physics in the interaction between fermions, the fundamental building blocks of all matter. The central component of this project is the design, construction and testing of a more compact and efficient  slowing apparatus, the Zeeman Slower. This multi-coil solenoid allows us to slow 6Li atoms from 1500 m/s to 20 m/s at which point the Fermi gas is trapped and studied.
    The improved slower is 30 cm long, utilizes only two power supplies and does not require water-cooling. It is more compact and has proven simpler to construct and maintain than the previous slower design and is capable of slowing an adequate number of atoms for our experiment. This document describes the motivation for the new design, as well as the construction and testing of the improved slowing apparatus.
