An annotated index of 186 cyclotron and accelerator documents — build reports, theses, lab manuals, datasheets, and classic papers — each scored on two axes: relevance (0–5, usefulness to someone designing or building a small cyclotron) and hands-on (0–5, concrete engineering content versus pure theory). Older hands-on literature from the 1940s–70s deliberately scores high: it documents machines at amateur scale, built with techniques an individual can reproduce.
This is a bibliography, not a document repository — no files are hosted here. Obtain documents through libraries, publishers, or open archives (many report numbers and theses are findable via a library catalog, OSTI, or an inter-library loan request).

Houghton College tabletop cyclotron thesis on the MAGNET/FOCUSING subsystem. Most beam current was being lost to Dee and chamber-wall collisions, so the magnet and chamber were modeled in Poisson Superfish with ion tracking in SIMION 8.1 to improve weak magnetic focusing while keeping field index n below 0.2 inside the max orbit. Concluded the best fix is replacing aluminum chamber lids with magnetic stainless steel lids 2.2 cm larger in radius than the Dee, theoretically doubling max proton energy to 900 keV, though phase slippage limits practical gain.
