The Pelletron accelerator contains up to 6 atm of SF6 gas in a sealed tank to insulate the terminal, which allows it to attain several megavolts (typical ranges are from 1 to 10 MV) without discharging. Inside the accelerator, the acceleration tube is...

Measurements of keV-neutron capture cross sections of RE nuclides (Sm-147, Sm-148, Sm-150, Ce-140, Pr-141, Eu-153, Nd-143, Nd-145) have been performed to evaluate the accuracy of the nuclear data libraries using the 3-MeV Pelletron accelerator of the Research Laboratory for Nuclear Reactors at the Tokyo Institute of Technology.

The negative ion beams from the ion source are injected into the pelletron accelerator at an energy of about 100 keV by the injector system. The two negative ion-sources are as given below ... 

The Pelletron accelerator at the right of the layout shown of Fig. 6.8 is mainly meant to produce 2 MeV He particles for Rutherford Backscattering Spectroscopy studies. Such studies [8] allow a depth selective analysis of the composition of a sample. In channelling geometry it can also be used to determine, with... 

High-energy ( MeV) monoenergetic positron beams have been built and used in recent years. MV accelerators used in this work have been of Pelletron or Van de Graaff type. Source-free lifetime measurements in a... 

Wood and bone samples, chosen from each site, were radiocarbon dated using the technique of AMS in The Poznan Radiocarbon Laboratory. The laboratory is equip>p)ed with a accelerator mass spectrometer type 1,5 SDH-Pelletron, Model Compact Carbon AMS".
