  Pelletron - Wikipedia, the free encyclopedia
Pelletron is a type of electrostatic particle accelerator similar to a Van de Graaff generator.
Pelletrons have been built in many sizes, from small units producing voltages up to 500 kilovolts (kV) and beam energies up to 1 megaelectronvolts (MeV) of kinetic energy, to the largest system, which has reached a DC voltage of over 25 megavolts and produced ion beams with energies over 900 (MeV).
Pelletron accelerators are used as analytical tools in many fields, including materials analysis, nuclear physics, semiconductor development and production, pharmaceutacal research, and as ultra-sensitive mass spectrometers for carbon dating and the measurement of other rare isotopes.

 Pelletron® Accelerator Charging System
Pelletron chains are made of metal pellets connected by insulating nylon links and are charged by an induction scheme that does not use rubbing contacts or corona discharges.
For a positive terminal Pelletron, the negatively-charged inductor electrode pushes electrons off the pellets while they are in contact with the grounded drive pulley.
Most Pelletrons, as shown in the charging system diagram, employ "down-charging" as well as "up-charging." Down-charging works identically to up-charging, except the inductor/suppressor polarities are reversed, and it effectively doubles the charging current capacity of the chain.

"Turns out," he says, "Pelletron was right down the road." Keneagy talked with Pelletron, discussed solutions, and soon had a P10 DeDuster running in the shop, inhaling all of the acetal dust it could find.
Other problems may be inadequate or inconsistent drying, clogging or reduced capacity in material handling systems, crusting of fines at the feed throat, and carbonizing in the melt chamber, which shortens screw life.
Pelletron reports that the system permits separation down to 1 µm and dust reduction down to at least 30 ppm.

 Nuclear Structure Laboratory, FN Tandem Van de Graaff Accelerator
To insure uniform acceleration of the ion beam as it passes through the FN Tandem, it is necessary to control the electric potential within the accelerator, which varies from ground potential at the LE and HE tank bases to as much as 10 MV at the terminal.
Equilibrium must be established between the charge brought to the terminal by the pelletron chains and that which flows from the terminal to ground through the column resistors.
Also, small irregularities in the links of the pelletron chain will tend to cause variations in the charge delivered to the terminal, and this must be compensated for.

In 1940 he and his collaborators introduced the use of three concentric high potential electrodes.In 1965 he founded the National Electrostatics Corporation (NEC), which is still today one of the leading firms for the construction of Van de Graaff generators and ancillary equipment.
This idea was developed for several years and finalily at the end of the 1950' and in the 1960' it was possible to find a good solution using a' string of beads' charge carrier, which evolved into the modern Pelletron.
Today most powerful Pelletron chain generators can deliver current of 100-200 µA and the potential terminal can go up to 25-30 MVolt.A different type of charging chain called Laddertron, was developedby the HVEC.
