Electrons in uniform magnetic field.

AI Thread Summary
When an electron moves through a uniform magnetic field, it experiences Lorentz force, causing its path to curve in a corkscrew shape. The discussion raises the question of whether this acceleration towards the center leads to bremsstrahlung radiation, which typically occurs with changing velocity. However, it is noted that this radiation does not manifest in the same way as with protons, leading to confusion about the differences in radiation between circular and linear accelerators. While synchrotron radiation is a concern for circular accelerators, linear accelerators also produce radiation, as highlighted by the Larmor formula. The conversation emphasizes the complexities of radiation in varying acceleration contexts.

Hello.

So I was wondering that when you shoot an electron through an uniform magnetic field, obviously Lorenz force starts to skew the path to that corkscrew shape that we all know. But then there is an acceleration towards the center of the circle, and if the the velocity of the electron changes, isn't there supposed to be bremsstrahlung radiation then? I don't think that it happens because then the electron should radiate and the radii should decay. Right?

But why? What is the difference between this and an electron that has it's velocity changed due to a proton?

Look up "synchrotron radiation." It's a factor in designing circular electron accelerators.
 
Yes I'm familiar with that, but isn't that only with the circular accelerators? So if I have a linear accelerator this would not be present.
 

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
