Title: Improvements relating to electron optical lens systems
Inventor: ARCHARD GEOFFREY DENNIS
IPC: H01J37/153
Filed: 1954-10-01
Abstract: 794,014. Electron lenses. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Nov. 29, 1955 [Oct. 1, 1954; Dec. 2, 1954], Nos. 28370/54 and 34973/54. Class 39(1). In an electron lens system for correcting spherical aberration, the beam passes successively through a series of lenses each of which consists of an even number of electrostatic poles of alternate polarity arranged symmetrically about the axis of the beam and so arranged that, by the operation of each lens in succession, the original circular cross-section of the beam is deformed, and the spherical aberration is corrected successively, in two mutually perpendicular planes transverse to the axis of the beam. Finally the circular cross-section of the beam is restored. As shown, a 4-pole lens A4 causes the beam to diverge in the Y plane and to converge in the X plane. A combined 4-pole and 8-pole lens B 4,8  corrects spherical aberration in the Y plane and, at the same time, causes the beam to converge in that plane. The 4-pole portion of B does not affect the beam in the X plane because in this plane it is converged close to the axis. The beam then deforms along the X plane where a combined 4-pole and 8-pole lens D 4 ,  8  corrects spherical aberration in that plane and also restores the circular cross-section of the beam. A 4-pole lens E 4  acts on the beam to retain the circular cross-section. An 8-pole lens C 8  corrects spherical aberration in the 45‹ planes, and may be placed after lens E 4 . According to the Provisional Specifications, the poles of the lenses may be charged spheres, rods, laminae, wedges or other shapes. A known lens system for correcting spherical aberration is described. The system includes cylindrical electrostatic lenses and 8-pole lenses for correcting the spherical aberration.
