pelletron

[′pelə‚trän]
(nucleonics)
A type of electrostatic accelerator that utilizes a charging system consisting of steel cylinders joined by links of solid insulating material such as nylon to form a chain; the metal cylinders are charged as they leave a pulley at ground potential, and the charge is removed as they pass over a pulley in the high-potential terminal.

Pero en la investigacion Latinoamerica esta muy modestamente representada en el mundo de los aceleradores, apenas con el Laboratorio de Campinas en Brasil, con la "Fuente de Luz Sincrotron" (2) y en Argentina, en Buenos Aires con el "Tandar" (3), (instalacion mediana de Tandem Van de Graaff actualizado a Pelletron).
The excess of silicon is introduced by ion implantation at room temperature with 1.5 MeV [Si.sup.+2] ions at a fluence of 2.5 x [10.sup.17] ions/[cm.sup.2], using the 3 MV Tandem accelerator (NEC 9SDH-2 Pelletron) facility at the Instituto de Fisica of the Universidad Nacional Autonoma de Mexico (IFUNAM).
According to the working mechanism, these scientists had worked at the main laboratory in CERN, developed in the northwest suburbs of Geneva on the Franco-Swiss border in 1954, carrying out research work simultaneously in line with the directives given by a team of senior CERN scientists using 8 MV Pelletron Tandem accelerator facility based on sophisticated technology at the NCP.
