could be used instead of a superconducting coil. This new drive circuit allowed for less demanding requirements on the SCR's for large caliber accelerrators (> 40cm). And finally, a combination of the pull-only mass driver and arc- commutated mass driver using only an accelerator (no decelerator and return line) was developed for use as a lunar launcher, see Appendix M. Research is continuing on coaxial accelerators at: M.I.T. and EML by Dr. Henry H. Kolm, Dr. Peter Mongeau, and their associates (induction accelerator, helical rail launcher, etc.); ARRADCOM by William R. Snow and his associates (solenoid accelerators); Sandia National Laboratories by Maynard Cowan and his associates (theta gun), internal research by General Electric and General Dynamics, and finally at Princeton by Professor Gerard K. O'Neill.
