Abstract
The stability of the cross-shaped electron beam (EB) in a vacuum magnetic sensor with a vertical p-type Si field emitter tip was investigated. The magnetic flux parallel to the EB, Bz, was detected by rotational displacements ΔΦ of the cross-shaped EB between the anodes, and sensed as a differential anode current normalized by total current ΔIa/Ia. The fluctuation in ΔΦ was within 1% over a duration of 90 s at Bz = 3.0 mT. The magnetic flux normal to the EB, Bx, was detected by the translational displacement ΔLy of the cross-shaped EB along the y direction, and sensed as ΔIa/Ia. The fluctuation in ΔLy was also within 1% at Bx = 3.0 mT. These results demonstrate that this sensor with a vertical p-Si emitter tip using the cross-shaped EB is able to detect the magnetic flux in an arbitrary direction with high sensitivity and stability.
