exp plot tip: If you use the "grid" feature of matplotlib and plt.semilogy(), the exponentials will look like straight lines, so we can just read off the time constants with a ruler.

Also, as we talked about earlier today, we should make some analytical estimates for the various heat loads, and also put them into the model.

For protecting from radiation, all of the surfaces which are NOT shiny-polished should get wrapped in something shiny (UHV Al foil, with the shiny side out).

I suggest wrapping with foil:

1. Baseplate (to keep it from radiating into the cold plate (the tapped work surface))
2. Copper strap (after first wrapping it with a sheet of Mylar to block conduction to the foil). Al foil should be wrapped with shiny side out.
3. Plastic spacers. wrap around the length, but not the ends.
4. Holes in the shields where the thermal strap enters. Edge the holes with a G-10 ring/grommet to prevent touching the straps.

I attach here a photo of the radiative shielding of a Purple Pepper Plant (PPP), to reduce the radiative coupling to the environment. This prevents the soil from drying out in the sun so fast.
