- We are running a new pseudo Ying experiment - status 17 August 92.
-
- We are running with alternate application of the 2 micro curie 60Co source on
- a 24 hour interval. This is the same cell as previously run, but we are
- operating on more of a Ying profile. Sorry, we can not yet tell the details.
- However, previous calibrations would indicate that the calorimeter electronic
- measurement should be very stable under this type of operation. There would
- still be a correction due to ambient temperature and cooling water
- temperature, see below.

- As weather patterns change there is a contribution from the various
- temperature control systems in my house. Normally at this time of year, we
- could count on continuous air conditioning. But this seems to be a more than
- usual abnormal year. Jennifer even turned the furnace on between point 7 and
- 8. For various reasons, I decided not to try to control the situation, but
- just let the house conditions go where Jennifer and the weather take them. If
- I interfere, I might try to introduce a favorable bias. The difference
- between on-line and off-line calibration is about a 10 mw rms weather
- variation. If we run long enough, a real trend should show up in spite of the
- variations due to weather, even in the raw data as above.
-
- I do notice that we seem to be accumulating more joules when the source is in
- than when out, and point 9 is unlikely to change that trend.
