Deep Space: The new frontier of radiation controls
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

Essential increase of operation efficiency of electron cyclotron resonance (ECR) multi-charged ion (MCI) sources (that is the increase of the average charge number and current of ion beams) is connected with possibility to achieve more dense plasma and to achieve so called quasi-gasdynamic regime of the plasma confinement in mirror traps using RF radiation with higher frequency. Results of experimental investigation of ion charge state distribution in a pulsed ECR source of MCI with pumping by millimeter wave radiation of powerful gyrotron are presented in the paper. Millimeter wave radiation with maximum power W=130 kW, frequency f=37.5 GHz and pulse duration up to 1.5 ms is used in the experiments. The charge state distribution maximum corresponded to argon charge (+13)-(+15). Total ion saturation current density of the probe achieved 2 A/cm2.
