Langmuir, Robert Vose (1943) A regulated high voltage supply for the electron microscope. Dissertation (Ph.D.), California Institute of Technology. http://resolver.caltech.edu/CaltechETD:etd-05132003-122821
NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. The errors of magnetic electron lenses are discussed, particularly with respect to the ultimate resolving power of the electron microscope. A regulated high voltage power supply using frequency modulated carrier system has been constructed which contributes considerably to the operation of the electron microscope at high magnifications. The errors of the magnetic lenses due to poor lining up and centering have been reduced considerably by operation at lower magnifications. A resolving power of about 150 [Angstroms] has been obtained. Some pictures of clays, calcite and rouge are presented.
