High current proton beams production at Simple Mirror Ion Source 37 Skalyga, V.; Izotov, I.; Razin, S.; Sidorov, A.; Golubev, S.; Kalvas, Taneli; Koivisto, Hannu; Tarvainen, Olli Skalyga, V., Izotov, I., Razin, S., Sidorov, A., Golubev, S., Kalvas, T., . . . , & Tarvainen, O. (2014 This paper presents the latest results of high current proton beam production at Simple Mirror Ion Source (SMIS) 37 facility at the Institute of Applied Physics (IAP RAS). In this experimental setup, the plasma is created and the electrons are heated by 37.5 GHz gyrotron radiation with power up to 100 kW in a simple mirror trap fulfilling the ECR condition. Latest experiments at SMIS 37 were performed using a single-aperture two-electrode extraction system. Proton beams with currents up to 450 mA at high voltages below 45 kV were obtained. The maximum beam current density was measured to be 600 mA/cm 2 . A possibility of further improvement through the development of an advanced extraction system is discussed. © 2013 AIP Publishing LLC.

“…These typically operate on volume sources at pressures of 10 -3 to 10 -2 torr. Electron-cyclotron ion sources can operate at pressures of about 10 -3 torr [Xu 2008] and can achieve uniform plasmas [Fu 2006]. The ion density at the accelerator grids must be very uniform to produce multiple beamlets that are each well focused.…”

The achieved performance of the gas dynamic trap version of magnetic mirrors and today's technology we believe are sufficient with modest further efforts for a neutron source for material testing (Q=P fusion /P input~0 .1). The performance needed for commercial power production requires considerable further advances to achieve the necessary high Q>>10. An early application of the mirror, requiring intermediate performance and intermediate values of Q~1 are the hybrid applications. The Axisymmetric Mirror has a number of attractive features as a driver for a fusion-fission hybrid system: geometrical simplicity, inherently steady-state operation, and the presence of the natural divertors in the form of end tanks. This level of physics performance has the virtue of low risk and only modest R&D needed and its simplicity promises economy advantages. Operation at Q~1 allows for relatively low electron temperatures, in the range of 4 keV, for the DT injection energy ~ 80 keV. A simple mirror with the plasma diameter of 1 m and mirror-to-mirror length of 35 m is discussed. Simple circular superconducting coils are based on today's technology. The positive ion neutral beams are similar to existing units but designed for steady state. A brief qualitative discussion of three groups of physics issues is presented: axial heat loss, MHD stability in the axisymmetric geometry, microstability of sloshing ions.
