摘要:
A new method of high speed oscillography has been investigated. This makes use of four‐pole lenses which enable the deflection of the beam to be magnified in only one desired direction. By magnifying the deflection by a factorkin both directions as in the conventional oscilloscopes, one loses in intensity by a factork8/3. If, however, a magnification in one direction is used, the loss is onlyk4/3.
