Erratum: Two Bridge‐Controlled Thyratron Thermostats

Fast Scr Thyratron Driver

As part of an improvement project on the linear accelerator at SLAC, it was necessary to replace the original thyratron trigger generator, which consisted of two chassis, two vacuum tubes, and a small thyratron. All solid-state, fast rise, and high voltage thyratron drivers, therefore, have been developed and built for the 244 klystron modulators. The rack mounted, single chassis driver employs...

Thyratron Modulators in Plasma Source Ion Implantation

Plasma Source Ion Implantation (PSII) is an emerging technology which can be used to harden metal surfaces in a conformal manner. North Star Research Corp. (NSRC) is building a unique implanter system for Empire Hard Chrome which will be the first truly commercial implanter of this type. The choice of pulsed power technology for this application is important from the standpoint of both reliabil...

Agn as Cosmic Thermostats

We present a simple analytical model and the results of numerical simulations supporting the idea of periodical heating of cluster gas by AGN outflows. We show why, under this assumption, we are extremely unlikely to observe clusters containing gas with a temperature below about 1 keV. We review the results from numerical hydro-simulations studying the mechanisms by which AGN outflows heat the ...
