- We are running a pseudo Ying experiment - status 30 July 92.
-
- The source is not expected for a week or so. This will give time for a number
- of 24 hour segments.

- Here the code was changed to synchronize the data points with the saw tooth
- down stroke. While the computation must be suspect, I think it is not the
- cause. My best guess for the following power increase is that the change
- caused a higher peak saw tooth current, and this generated more "anomalous
- heat". There are a lot of saw tooth changes, even in the data of this run
- which do not show computed power changes.

- Point 22 will likely come out larger than 21 so it sort of looks like we have
- the "in-out" effect on top of a rising trend.
-
- While every time I "so something" I suspect that it might cause a calorimeter
- zero change, the calibration and null runs have been so stable that I consider
- any thing over a 10 mw change to be significant.
-
- Here is my theory for the above data with my "true believers" hat on.
- Starting at point 8 the time lag in the effect washed the "in" data into the
- "out" data. When the program change was made, the increased current caused a
- temporary increase in the "anomalous heat" which is decaying exponentially.
- This reached its low at point 18, and "anomalous heat" is now building again
- due to the cumulative effect of the source.
-
- With my "true believers" hat off, it looks like nothing is happening.
-
- With the program change, we can look for information in the relatively smooth
- data between the above points. By grouping all the power points in one saw
- tooth together there is a nice smooth trend with an occasional up bump. I
- will try to get this data into shape that it can be passed out to those of you
- that want to look at it.
-
- Dennis Cravens has suggested that the source might change the efficiency of
- the thermoelectric refrigerator. To get positive "anomalous heat" the
- efficiency of the refrigerator set that pumps heat out of the calorimeter
- would have to decrease. Note that this set runs at about 1/2 ampere. Those
- of you that like to compute such things have a go at this. This will be
- tested by the cell out calibration at the end of the run.
