Abstract

A neutral injector with Energy Recovery has been designed and tested. A new type of electrode, the STEM, has been developed for this injector in view of electron suppression and trapping. A first series of experiments were made with H, D and He beams, up to 60 keV, 12 A, 0.5 s duration. The recovery of the unneutralised part of the beam has been clearly demonstrated. The decelerated ion collector potential was as low as 0.05 Vbeam. At least 90% of the full energy residual ions are collected.
