$I\frac d {2\pi R}$ is $\vec I \cdot \hat n$.

So "people" screw things up. Instead, re-frame the problem with weights on a slider held by over stretch springs (that are pinned). Remove the pin, what happens?

@TariqBY no can do, I've moved well beyond that stuff.

@NíckolasAlves It was just called "Erlangen" when I was there.

@JeremyKievit well, it's closed. So read en.wikipedia.org/wiki/Harmonic_oscillator You write the solution as $e^{ift}$ ($f$ is angular frequnecy), so at FT turns the differential eq into an algebraic eq: $(f^2 +2\gamma \omega_0 + \omega^2_0)=0$ From there, apply quadratic formula and pick the decreasing solution. This is the most useful problem in physics and engineering.

hmm, I worked at DESY and don't know what FAU is. It's not ETH.

Ballistic trajectory means falling, so you have to ensure it's not falling, which requires gravity to provide the centripetal force at the apex, which sets the VCM, which I converted to energy--the top and bottom of the loop have a potential energy difference, and VCM corresponds to 1/4 of that.

@PhysicsDave photomultiplier tubes detect single photons, so maybe a fly's eye cosmic ray telescope (Cherenkov showers), or "neutrino telescope", but optical focusing stuff: no way.

did you follow the link to: smtn-002.lsst.io ? Note that these are highly technical design documents, and unless an expert with knowledge of the project chimes in: you can read just as well as the rest of us.

@mmesser314 I'm addressing your concern now, but I have to go work. (which is in radiometry from space....I hope my colleagues don't see my first answer..).

but it's not a blackbody spectrum (duh). At the wavelength, if we say $\epsilon=1$, the brightness temperature is insanely high--hot enough for fusion, but IR-UV is so far below the Wein's Law peak frequency..so idk. I just don't think of a laser a thermal radiation --so the answer could be yes: look at NIF, it gets really hot.
