Title: Electronic shock semiconductor amplifier
Inventor: MITA OSAHISA
IPC: H03F99/00
Filed: 1981-02-16
Abstract: PURPOSE: To improve the linearity of input and output characteristics by forming two sides of the detection surface shape of a semiconductor detector in the same shape with part of the circle of an electron beam spot contour, and making the other two sides parallel and straight.  
     CONSTITUTION: A prescribed voltage is applied to anodes 11 and 13 and a voltage applied to an anode 12 is adjusted, so that an electron beam 4 emitted from a cathode 5 forms an image as an electron beam spot 7 on the surface of a semiconductor detector 14. Two sides (ab) and (cd) of the detection surface (abcd) of the detector 14 are made parallel to the deflection direction AA' of the beam 4, and the other two sides (bc) and (da) are formed in the same shape with part of the circle 15 of the contour of the spot 7. Consequently, the area of the shock reception part 20 of the beam 4 varies linearly with the extent of the deflection of the beam 4, so the input and output linearity of an electronic shock semiconductor amplifier shows linearity.
