Title: Use of a New Ion-Detector in the Study of the Jet Plasma Injected into DECA I; UTILISATION D'UN NOUVEAU DETECTEUR D'IONS DANS L'ETUDE DU JET DE PLASMA INJECTE DANS DECA I

Technical Report ·
OSTI ID:4719438

The development of a high-sensitivity ion detector coupled to an electrostatic analyzer permitted an investigation of the plasma jet injected into a pulaed magnetic mirror configuration. In this detector the positive ions are accelerated through a potential of 30 kv: they strike a metallic target, on which they produce secondary electrons; these, in turn, are accelerated onto a plastic scintillator. The light pulses are detected with a photomultiplier. The gain of this device is about 10/sup 7/. If air is admitted into the vacuum system, then re-evacuated, the gain is not modified since no special activated surfaces are situated in the detector. (auth)
