The ion polishing system 691 PIPS made by Gatan is designed to produce high quality TEM specimens having exceptionally large, clean, electron transparent areas. Ion polishing is done by two variable angle, (± 10°), miniature Penning ion guns. Specimen’ contamination is reduced by using an oil free vacuum system consisting of a molecular drag pump with pumping speed for argon of 60 l/s. The single-sided specimen post provides excellent thermal contact with the specimen and prevents specimens from being overheated by the ion beam.
