1e-11 at 1 second is the XPRO spec (and 2X better than LPRO or
PRS10). There are good (physics) reasons why those units all draw
100X more power than a CSAC.
CSAC is intended for portable battery-powered operation. Surely
your basement has the space and wallplug power to support an LPRO.
(p.s. don't cool the damn thing, heat it).
The cats were much happier during the CsIII development (see http://
home.comcast.net/~rlutwak). It was bigger and warmer. Any Cat-Nuts
out there who can help me find one with significantly lower SWAP?
You know, that gives me an idea...I could justify some interesting
equipment if I assured the XYL that it was simply a cat bed heater.
As for this heat sinking of a Rb, might it be better to use a
refrigerator? More practical.
