A dedicated optical system is designed for the breakdown of first ITER plasma, when machine will not be equipped with equatorial ECRH-launcher. Seven beams from upper launcher transmitted via several in-vessel mirrors through resonance layer to a beam-dump. The whole was simulated PROFUSION package obtain beam parameters, estimate spill-over effects and determine required polarization in order ...

This paper extends an imperfect production inventory model to machine breakdown at a random time and rework of defective items. Any manufacturing system wants to produce perfect quality items. But in long run production process, there may arise different types of difficulties like labor problem, rawmaterial problems, operator problems, etc., due to that the machinery systems shift from in-contr...

Measuring and controlling the longitudinal phase space and the time-slice emittance of the electron bunch entering at 1.2 GeV in the undulator beam-lines, are crucial to obtain high FEL performances. In the FERMI@Elettra machine, two RF deflecting cavities have been installed at the end of the linac, in order to stretch the electron bunch horizontally and vertically, respectively. The two cavit...
