Publications

Since the development of the ram accelerator in the mid 1980's, there have been numerous papers and articles written to portray its applications and contributions to fundamental science. In addition, each year, ram accelerator personnel present papers on their current research at professional conferences and workshops.
If you'd like to learn more about the capabilities of the device, please look at some of the papers listed below.

Presentations at Past Workshops

There have been four international workshops on the ram accelerator (1993, 1995, 1997, 1999). The proceedings from the latter two workshops have been published separately. Representative proceedings papers from the UW are included below.
