Well, I'm trying to find the irradiance of synchrotron radiation emitted from an electron beam. The equation I have for irradiance requires the temperature of the radiation source. For example, the Sun is something like 5760 K, so I was looking for a way to calculate a similar temperature for...
I was curious. Does anyone know of anywhere were I might be able to find a formula for calculating the temperature of an electron beam? I already know the frequency and energy levels (actually calculating for multiple energies, so I have a spreadsheet I'd like to plug the equation into).
Actually it is! It's for determining the power of synchrotron radiation emitted from a particle beam, essentially the relativistic form of the Larmor formula. But anyway, someone at work was able to point me in the direction of a different equation in SI units, and the results seem to be...
In doing some research, I cam across an equation for instantaneous radiated power, with the CGS units "erg/(sec rad cm)", rad being radians (not rad the unit for radiation exposure). Try as I might, I'm not able to come up with a way to convert it to the SI units for watts. Does anyone know...
I just saw a thread about "easier" methods of nuclear fusion. I have a concept of my own, but I'm not well enough read on plasma and particle physics to know if it would work.
Basically, my idea is nuclear fusion minus the nuclear; instead of fusing hydrogen isotopes, fuse electrons. From...
Okay, I thought about it some more, and I realized: I will need to factor in the change of pressure and density, because the maximum altitude is when the buoyant force is equal to the weight. Duh. Now I'm off to figure that out.
I feel kinda stupid asking this, since I have a bachelor's degree in physics. But, here it goes: I'm doing a thought experiment on my own (i.e., not a homework problem) for a hypothetical vacuum airship. I've determined the following quantities:
V_displaced = 15 m^3
m = 13.5 kg
F_net =...
