I did a small analysis with the custom data acquired on August 26, 2020. The results are summarized in Flux_levels.png image. Copying from what I wrote on slack in #commisioning channel: We are saturating all lamps at 5sec, getting close to saturation for all lamps with 3sec - although I have not been able to take data with Krypton (I tried 3 times). HgAr saturated at 1 second already. There is certainly still some jumping of effective expTime, i.e., I see that actual expTime does not correspond to the requested one. We discussed the flux during SPS telecon today, we probably want to have lower flux so that uncertainty of cca 1 sec in expTime that we see is not affecting us that much. |
