Since it might be possible to use high strength ceramic magnets that can generate
20 gauss through the CRT cover without removing it from the scopes ( there is
already a slight deflection due to the ~ 0.5 gauss earth's magnetic field) the beam can be
"calibrated" by centering it at low intensity, then bringing the magnets close enough to the sides
of the scope for the spot to deflect up or down about a centimeter.
If there is a dim (*e-) spot (with a safe intensity for the e beam spot) it should appear above or
below the e beam spot.
Thanks.
