If the particles loose kinetic energy without radiating, where does the energy go? Come on, Ralph. You are claiming that the re-updated Wilson Field Theory state that charged particles, like electrons, don't emit photons when they loose energy.

According to the WFT is synchrotron radiation emitted when charged particles gain kinetic energy in an electric field. BTW, Ralph. Do you know why the next generation high energy accelerators (after LHC) probably will be linear accelerators? Hint: Synchrotron radiation.

But you have explained nothing yet. To repeat the probably still unanswered questions: If the synchrotron radiation is emitted from the magnetic bending field, from where does the radiated energy come? It is not fed into the bending magnets. If the particles loose kinetic energy without radiating, where does the lost energy go? -- Paul http://home.c2i.net/pb_andersen/

You asked if the charged particle that is emitting synchrotron radiation was inertial. Either YOU weren't thinking, or you don't know that inertial particles don't radiate. It probably was the former, so why don't you admit that in stead of pretending that your question was a sensible one. >>> >>> Consider a linear accelerator in which a charge is being slowly accelerated. >> >> Why would we consider that? We were talking about synchrotron >> radiation in a wiggler, not anything to do with a linear accelerator. >> >>> It >>> is obviously not inertial and it appears to intermittently emit an EM quantum. >>> >>> Q1) How, when and why does it emit an EM quantum? >>> >>> That process is dependent solely on the particle's acceleration so: >> >> No, it's not solely dependent on the particle's acceleration.

In the particle's frame of reference, radiation _is_ emitted in all directions, but not equally intense in all directions. (If we are talking about a single photon, replace 'intensity in a direction' with 'probability of emission in a direction'). In the frame of reference of the particle, let's call it the S' frame, there is a moving magnetic field. So the velocity vector is still relevant, but here it is the velocity of the B field. The moving magnetic field is perpendicular to the velocity. In the S' frame only an electric field can accelerate the particle. When we transform the moving magnetic field to the S' frame, the electric field is E' = -v*gamma*B, and the direction is perpendicular to the B field and the velocity. So the acceleration is perpendicular to same. The radiation intensity distribution is: I(phi') = Io*cos^2(phi') where phi' is the angle from the velocity vector. Note that for phi' = +/- pi/4, we get I = Io/2, the intensity is half at these angles. This is often called the beam width. So it will radiate almost in all directions, but mostly in both directions along the velocity vector, and nothing perpendicular to it. The radiation diagram will be something like this: (should be two circles) . . * * * * * * * * ----*-----------C-----------*-> v * * * * * * * * * * But we are observing the radiation in the lab frame S, where the particle is moving at the speed v. The intensity at the angle phi = 0 (in the forward direction) will be changed by the square of the Doppler effect: I(0) = Io*(1+v/c)/(1-v/c) equivalently will the intensity in the opposite direction be: I(pi) = Io*(1-v/c)/(1+v/c) (If you think in photons will the energy of each photon be Doppler shifted, and the frequency of arrival of photons will also be Doppler shifted, thus the square.) In addition to this effect will we have aberration: cos(phi) = (cos(phi')+ v/c)/(1 + (v/c)cos(phi')) A beam (or photon) in an off axis direction in S' will be deflected towards the velocity vector in S. It can be shown that the combined effect will lead to a beam width (half intensity) ~= 1/gamma (radians) in the forward direction. For high gammas will we have a very narrow beam along the velocity vector and very little in the backwards direction. Note that this is a prediction of SR, and measurements are in accordance with the prediction. Synchrotron radiation is yet another confirmation of SR. > So I am right. It is dependent solely on the particle's acceleration. No. Observations in the lab frame depend strongly on the particle's velocity in that frame. >>> Q2) What does that say about the direction of radiation in a linear vs a >>> circular accelerator? In any accelerator will we loose a little energy as radiation in the RF-cavities due to the acceleration of the particles. But most of the energy goes into kinetic energy of the particles since the acceleration is along the velocity. But the acceleration of the particles in the bends is much higher than it is in the RF-cavities, and the radiation is _vastly_ more intense. And since the acceleration is perpendicular to the velocity, it doesn't add to the kinetic energy of the particles. The radiation energy is taken from the kinetic energy of the particles, so they loose kinetic energy. In its rest frame, the particle "sees" an electric field E = v*gamma*B. When v ~= c, gamma is thousands and B is very high, that's a gigantic electric accelerating field! That's why the next generation of high energy accelerators probably will be several km long linear accelerators. -- Paul http://home.c2i.net/pb_andersen/

It should be noted that S' is the inertial frame where the particle is _instantly_ at rest. -- Paul http://home.c2i.net/pb_andersen/

Hahahahhaha! Of course they don't. As with the aforementioned rock, they energise the field and IT emits the radiation ....at c wrt the field electrodes....

Well I would be inclined to say that it does not because all the applied energy goes into the particle's increased KE. This is a very different situation from that whereby a charge is deflected by a magnetic field and slowed in the process...(why is it slowed?) However even when a charge is accelerated by a field, there should be a reverse reaction ON that field ...and that could cause radiation emission FROM THE FIELD ITSELF. >BTW, Henry. >Do you know why the next generation high energy accelerators >(after LHC) probably will be linear accelerators? >Hint: Synchrotron radiation. >(They don't use the WFT in the design. :-) ) Of course they do...but they are too ignorant to realise the fact. ...The design is the same. ..... >>> The energy in the synchrotron radiation is huge in >>> a large synchrotron.
