New cooling and inductance features that are set up in stages. The first stage is a machined aluminum pole sleeve. This provides better heat wicking and is the first portion of inductance linearizing and reduction. The second stage is a combination of the pole sleeve and an aluminum domed compression cap. This increases the compression ratio for cooling as well as adds some outstroke inductance reduction. The third stage utilizes the pole sleeve, the compression cap, and a thick aluminum finned extrustion that again lowers and linearizes inductance as well as aids in thermal dissipation. With the third stage we have reduced inductance by almost a factor of 3 over utilizing none of the aluminum.
