| Abstract: | The design of double-tilt TEM holder with magnetic field is described in this paper.A special U shape magnetic coil is fixed on the tip of the hold and the strength of the magnetic field can be adjusted by the external current.The sample cup is truncated to ensure that the sample faces the magnetic field.The U shape coil can applies equal but direction-counter Lorentz force on the electron beam to limit the beam shift and avoid the image distortion.The in-plane stable magnetic field can be kept as 100 Oe and instantaneous strength can reach 140 Oe. |
