[Hps] Run progress chart updated.

[Graf, Norman A.]

Thanks Maurik,


That's a very useful graphic. This plot should provide some motivation and, as Tim points out, there's some reason for optimism.

And the yellow line flat-tops on August 22, whereas the extension gives us a chance to catch up.

Thanks Maurik,

On the upside, during the week it was steady (mostly 150 nA to keep from killing all the FEBs due to backgrounds), you can see that we were breaking even during the brief period we ran at 200 nA, so if we can get steady again at 300 nA equivalent, or even 250 nA (now that it seems we are running cleaner/safer) we can still collect a powerful dataset.

Dear HPS,

I just finished improving the script that creates the run progress chart so that it now runs in a single step.

The new chart is here: https://urldefense.proofpoint.com/v2/url?u=https-3A__plot.ly_-7Emaurik_31_-23_&d=DwIF-g&c=CJqEzB1piLOyyvZjb8YUQw&r=ErLkbYGWd8oSAZ70ywHxhA&m=lIr9qlre_SzvU1dc-TERUg7aJWgkCZDGLDoA9A8Jo20&s=YurhbhfC7EqgBi-FtU7ed1ir3drhr2Xs9L2efl3phUc&e= <https://urldefense.proofpoint.com/v2/url?u=https-3A__plot.ly_-7Emaurik_31_-23_&d=DwMFaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=ErLkbYGWd8oSAZ70ywHxhA&m=r4HSOCSbetaheOwhsLdQMgjJxmz4sxRnFmY1WR07hUw&s=uJaVf7f53kaA8XwZ2Si97O5Hrdheqq0dMh9AX3dQXZk&e=>

By request, I added the rather depressing line of “proposed charge”, which is the charge that would have been accumulated if we ran at 300nA with 50% efficiency.

Best,
Maurik
