Re: Photon, Momentum, Mass

There are dozens of synchrotron light sources operating in the world
today, which generate X-rays and deep UV light by "wiggling" an electron
beam magnetically. The synchrotron radiation travels at c in the lab
even though the electron beam that generated it travels at >0.999 c.

So! You have a slow moving magnetic field and a fast electron which do
you claim is the source?

What makes you think the magnetic field is 'slow moving'? This would depend
on the design of the syncrotron. Besides, since when do slow moving magnetic
fields radiate x-ray radiation?

You have a bunch of fast moving particles, for example, a beam of electrons,
circulating around inside the syncrotron.

It is a combination of both.

It is the BENDING of the beam of electrons. The bending could be done with a
magnetic field, an electric field, or with a pulsed magnetic or electric
field (which could be moving at a high speed).

Just as long as the instantanious strength of the bending field was correct
at the instant that the batch of electrons arrives, syncrotron radiation
would be produced.

If an electron
orbiting a nucleus changes orbit from one angular momentum to another a
photon is emitted.

True, but not applicable to this case.

Is it emitted by the electron?

Yes. But not applicable to syncrotron radiation.

Is the electron the
'source'.

Yes. The electron makes a transistion between energy levels.

No if it were you would get a spread of frequencies because of
all the various orientations of the atoms and the random points in the
orbit when the change took place.

You do. But not applicable to syncrotron radiation.

You are talking about something like neon gas in a gas discharge tube. You DO
get a spread of frequencies (doppler broadened by thermal motion of the ions)
and you do get light radiated in all directions.

Some electrons would be travelling
towards you, some away.

Some are. But this is not applicable to syncrotron radiation.

Doppler spread would reflect this.

It does, but this is not applicable to syncrotron radiation.

There is a
Doppler spread but that is accounted for by thermal agitation of the
atom as a whole.

Correct, but this is not applicable to syncrotron radiation.

The atom as a whole is the source not the moving
electron.

Incorrect and not applicable to syncrotron radiation. That is like saying 'it
is the gun as a whole that is the source of the bullet'.

Electrons can be paired with other particles to form 'atom like' structures.
They still have emission spectra. Electrons can be confined inside an
electrostatic 'box'. They still have emission spectra. The gun makes the
handling and firing of the cartridge more convienient, but it not necessary.
People have been injured and killed by gunless cartridges.

Besides, there are no radiating atoms 'as a whole' in the syncrotron. You
have bunchs of particles that are moved around inside the syncrotron.

In some sections of the syncrotron, ac electric and/or magnetic fields are
used to accelerate each bunch of particles.

In other sections, the 'beam' is bent by a static magnetic field. This WILL
produce syncrotron radiation.

In other sections, the 'beam' may be 'wiggled' (repeatedly bent back and
forth) to produce a strong, concentrated beam of syncrotron radiation.

In the last two cases, it is the electrons that are the source of the
radiation. The electrons are moving at a high velocity.

This is a valid test of c+v.

However, if you still believe that the static field is the 'source', rather
than the batch of electrons, it would be possible to modulate the magnetic
field so that it was also moving and reaches the necessary strength just as
the batch of electrons makes its appearance.

Perhaps someone with access to a syncrotron would be willing to try it. I
don't expect that the experiment would convince those who believe in BaTh,
however.

There are natural phenomina involving rapidly moving magnetic fields and
charged particles. (Solar Flairs, for example)

These produce radiation by the same mechanisms. None of these have been shown
to produce c+v photons.
