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).

Your question could apply to any of many electron beam applications. Here is one article pertaining development of a cool electron beam being developed to cool an antiproton beam at ~ 8.9 GeV. Can you be more specific?

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 the e-beam. I'm actually calculating it for multiple passes on a recirculating linac (a la CEBAF at JLab), so I needed a general formula with certain energy, current, wavelength, etc.
 
Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
