As a new turbo molecular pump has become available, certain high vacuum experiments have been carried out to investigate the properties of high frequency in a vacuum environment. The video above shows the use of the mentioned turbo molecular pump and heating elements for attainment of ultra high vacuum.

The following photographs and descriptions will confine itself to the first bulb presented in the video, in which a completely devoid vessel is employed. All specific phenomena observed in this bulb is described in the above mentioned video. The below photographs will aid the viewer in a more detailed viewing of the observed effects.
