Post HEAS superlative fusor V runs - The report
Posted: Thu Oct 07, 2021 1:36 am
I have sufficiently decompressed following last weekend's event and have reduced the data for the best three runs during the event. The best three runs strained my supply voltage limits at 46kev but no where near my current limit of 30ma. With these limitations, it was all about D2 pressure. I will include the run data as in the previous warmup post, prior to the event. I will also attach, in order, the Rhodium decay activation graphs. All count CPM data reported is that accumulated on the 3He counter over the last one minute of operation, (max counts/min). This typically is used to figure max TIER.
Run #1....10/1/21 ~10PM.....46 kv........11ma.....12 microns.....114,686CPM......561,961TIER
Run #2....10/2/21 ~3PM......45............13........13................152,048...........760,210
Run #3....10/2/21 ~11PM.....45............16........14.5.............163,233...........816,315
Rhodium activation graphs below Best first 5 second count equaled almost 2000 cpm peak activation level which is approx. 53X background.
It will be noted that the 3rd graph's TIER was higher, but the peak activation number on its graph is lower than the 2nd graph with a lower TIER number. I can elaborate in a reply why this is so, but only if asked to do so.
