[Mac Mestayer]

That's right.
My slide was confusing; I first stated that result because I thought the earlier run
had been taken with 85 ppm of O2, but later I looked up the exact run time and
saw that the earlier run had an O2 content of about 290 ppm as Sebastian points out.

I should let Mac comment, but this is actually not true - the 2 runs he compared had 290 and 340 ppn O2 content, not 85 and 340. We are trying to analyze a run with the low concentration right now, so the answer will have to wait.

Hi Dan,

  thanks for taking the minutes.
Maybe you could add this point of interest:
Mac studied the dependence of tracking performence (hits per track segment) on oxygen content. He found the effect to be small: An increase in O2 content to 340ppm from 85 ppm led to 0.4% decrease in hits per segments.

Veronique.

Dear all,

Please find the minutes of today’s Hall B group round-table meeting at the link below.

The topics discussed today included i) the status of the ongoing RG-F run and the upcoming
plans, ii) the second round of tests of streaming readout in Hall B with the FT system that
began late yesterday, and iii) the status of the progress and timeline toward the first CLAS12
publications.
