| Description |
Thermionic Emission Microscope
(THEM) developed at CEERI has an electrostatic
immersion lens to magnify the image. The geometry
of lens and potentials are optimized to achieve a
magnification of about 15 times with a clear image.
The design of deflection plates and lens are carried
out using OmniTRAK 3-D to ensure required
deflection of beam without losing laminarity and
beam interception with plates. Faraday cage,
containing a narrow aperture, is designed to obtain
elemental currents with low secondary emission.
The emission picture of a B-Type cathode has been
obtained. The results are satisfactory.
