Abstract
PURPOSE:To enable the detection of superconducting phase difference of a superconducting wire, by forming a loop by making two electron beams from the same source intersect in the front, making magnetic flux generated by the effect of the superconducting phase difference of the superconducting wires pass through the loop, and detecting the change of phase difference of intersecting electron beams. CONSTITUTION:Interference fringes 7 are formed, by making two electron beams 4, 5 emitted in different directions from an electron beam source 2 intersect by bending their travelling direction. A shift is generated in the interference fringes 7, by arranging a superconducting wire 8 in the manner in which magnetic flux generated by the effect of superconducting phase difference of the superconducting wire 8 passes through an electron beam loop 6 formed by the two electron beams 4, 5. By using said shift S the superconducting phase difference of the superconducting wire 8 is detected. For example, the two electron beams 4, 5 emitted in different directions from the electron beam source 2 are bent inside by biprism 3, and intersected with each other in the front to form the electron loop 6. The interference fringes 7 is formed on a screen like a photographic plate arranged at the cross position. A superconducting wire 8 is arranged between the biprism 3 and the interference fringes 7.
