Tandem Accelerator tandem accelerator[′tan·dəm ak′sel·ə‚rād·ər] (nucleonics) An electrostatic accelerator in which negative hydrogen ions generated in a special ion source are accelerated as they pass from ground potential up to a high-voltage terminal, both electrons are then stripped from the negative ion by passage through a very thin foil or gas cell, and the proton is again accelerated as it passes to ground potential. Tandem Accelerator a high-voltage accelerator in which by means of a charge exchange—or change in the sign of the charge—of the particles the same accelerating voltage is used twice. |
