It's not as complicated as it may seem...
Ditto, glad to see you weathered the storm. :)

In a thermionic valve are photons emitted along with electrons from the heater, the reason i ask is if a crt has a cross suspended inside and the electron gun fires at the cross then a shadow appears on the phosphor, now if a magnetic field is applied you get 2 shadows, one moves relative to the strength and direction of the magnetic field, this could be called the magnetic shadow effect, the other shadow is resultant from photon emission, photons do not get deflected by a magnetic field and do not exhibit the magnetic shadow effect.

I'm interested in reading about such an experiment. I thought applying a magnetic field only distorts the electron beam shadow of the cross. Since all electrons are supposedly the same mass and charge there should only be one electron beam shadow of the cross.

As far as 'magnetic shadow casting' goes.... when I was working for my Uncle Sam a magnetic shadow was simply the shape/density change of magnetic field lines (magnetic flux) caused by the presence or movement of anything that could distort those field lines. i.e. A compass needle or a submarine hull in the Earth's magnetic field or a moving vehicle on a highway with those magnetometer-like sensors embedded in the pavement. Magnetic shadow casting was some unexplained method or product that projected a magnetic shadow to hide the permeable object.

I'm sure some similar action went on with CRT's. Maybe, to prevent the effects the Earth's magnetic field had on them?

It's turtles all the way down
Thanks Guys

Power was out for several days and some UPS's from the basement hooked to the large batteries in the GE electric tractor helped with lighting and really important things like grinding coffee beans in the morning. ;).

Made me remember how fragile we are, and what a good idea alternate energy sources are.

There is only one electron beam shadow but this leaves the undeflected shadow of the photon which was cast by the same source of the gun.

See experiment 2 Maltese cross at the bottom it mentions the photons casting.

Here's a paper that looks at the magnetic shadow effect around planet Mars

The magnetic shadow effect seems to be akin to radiant energy, energetic particle deflection which is the result of a magnetic or electric field and a target object in the radiant path, in the case of photons it could be used to separate the particles and because the mass and energy of the radiant stream particles varies it would be possible to cast a varying shadow with distinct groups, a bit like a prism refracts light into streams of different wavelengths.
You could say there are 2 separate effects , electric shadow and magnetic shadow, SM mentioned only Magnetic, this is interesting so i now need to work out why, and i feel that it could be due to him using a solid medium instead of a vacuum in which he creates the refraction of radiation.

Wonderful knowledge on electron emission.

I'd like to expand some idea on this process.  It seems to me like a photoelectric effect but this happens to wire.  The picture I have illustrate current flow through the wire hitting atoms knocking electron out.  Electron eventually fall back to the atom but there is a possibility that it come back with more energy if reflect back from moving medium.  This idea is similar to the sling shot effect which steal momentum from other masses.
