Funding: The work was supported by Russian Science Foundation, Grant No. 16-12-10343. The main latest activities in the field of ECR ion sources development at the Institute of Applied Physics (Nizhny Novgorod, Russia) are connected with transition from pulsed to continuous wave operation regime of a high-current gasdynamic sources. The main advantages of such devices in pulsed operation are extremely high ion beam current with a current density up to 600 -700 mA/cm2 in combination with low emittance i.e. normalized RMS emittance below 0.1 pi mm mrad. To continue development of a CW gasdynamic ion source a new experimental facility called GISMO (Gasdynamic Ion Source for Multipurpose Operation) was construction at the IAP RAS. The source utilizes 28 GHz/10 kW gyrotron radiation for plasma heating in a fully permanent magnet system with magnetic field configuration close to simple mirror trap. The first plasma in GISMO was ignited in the 2018. Status of the new source development will be presented. |
