Dave, The cost of the lab and the cost of A/C must also be factored in. To keep a maser room within 1 C or 0.1 C takes much more power than the maser itself. Add to that the power consumed by the UPS(s) and all the other support instrumentation required to tend to a maser and it adds up, in both power and money. Ole's estimate of 1-2k/yr is much closer to the truth than your $161/yr. /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
