so uh, apparently some people at Fermilab have been cooling Nb SRF cavities down to 11 mK o.O
<SnoopJeDi>
even weirder: cavity Q goes *up* with increasing temperature at extremely low temps.
<SnoopJeDi>
(until you hit conventional temps > 1 K and then the regular relationship comes back)
<SnoopJeDi>
Hopefully the work they're doing at ultracold temperatures will shed more light on exactly what the hell is going on in niobium, though. An actual microphysics theory of SRF would be Super Duper Useful™
<SnoopJeDi>
rather than the conventional "iunno something something flux vortices?" ¯\_(ツ)_/¯

wtf Mars InSight is launching from Vandenberg AFB?!?
<bofh>
egg|phone|egg: wtf, I think you're doing something wrong in that case since double-double really *should* do the sensible thing there.
egg|doubledoubledouble|egg has joined #kspacademia
<egg|doubledoubledouble|egg>
bofh: what do you mean
<bofh>
like if implemented correctly double-double +/- *should* be faithful.
<egg|doubledoubledouble|egg>
I'm going by 10.1145/355958.355960 ?
<bofh>
sec, let me d/l the code and poke at it.

bofh: yes! do you have any idea what the launch profile is? is it going prograde?
<iximeow>
vandy is predicted to be a little cloudy on saturday so i'm trying to figure out if i should go somewhere else for a better vantage point
<iximeow>
"Launching toward the east adds the momentum of Earth's eastward rotation to the launch vehicle's own thrust. For InSight, the Atlas V 401 offers enough performance to enable launching a Mars mission southward from Vandenberg"

60 mm f13.3 with Mahler's on a losmandy

Yes it's an odd combination

that is indeed an odd combination, f13.3 is pretty steep

<SnoopJeDi>
saw some symplectic integration posters today you might have liked, egg|phone|egg
<egg|phone|egg>
UmbralRaptor: got M5 in the anbobinos easily
<SnoopJeDi>
including one on the Störmer problem
<egg|phone|egg>
I should get a big finder
<SnoopJeDi>
(well, kinda. the Störmer problem was a toy problem for the general method developed for a particular code)
<egg|phone|egg>
Snoop: the charged particles thing?
<SnoopJeDi>
yea
<egg|phone|egg>
UmbralRaptor: Jupiter very sharp now though
<SnoopJeDi>
it was by the software company I've collaborated with, one of their ongoing projects is adding some symplectic integration to a tracking code that handles spin-polarization
<SnoopJeDi>
which is very in-vogue right now because of the push for a polarized electron-ion collider (both JLEIC and eRHIC would have to maintain very high beam polarization in arbitrary patterns)
