This should be the end of the sad saga of recooling
simulations drawing out forever. Plot show the time-resolved
fluorescence from an ion allowed to heat up for 25 seconds in the second
incarnation of Signes trap. Solid lines are Monte Carlo simulations for
axial mode temperature of 3.75K with radial modes at (0K (black), 1/f
(Red), and 3.75K (Blue)).
Oh – dashed line is the analytical model. Janus might not do numbers so
well, but he does know his pen and pencil!
Simulations were done in Mathematica. This is the first time I try doing
hardcore numerics with this system and I was pleasantly surprised: It’s
surprisingly fast if you tweak it, and you just can’t beat having a
strong symbolic machine available for setting up the problem.
