Nathaly Santiesteban | Summary of the discussion with the theorist Jerry Miller and Wim Cosyn.
Higher order effects b3,b4 will have a contribution in the extraction of b1 and also in the Azz measurement. Therefore, the direction of the magnetic field may reduce those contributions. Currently, there are proposed two configurations: i) longitudinal with the electron beam (as it is in the proposal) and ii) along the q-vector. Wim will estimate the impact of having one with respect to the other to have the best configuration to be used in the experiment. However, this may be limited for the chicane and the beamline at Hall C. In which case, we need to run parallel and estimate the uncertainties accordingly. |

Updates from Dustin: Chris has contacted him and he has informed that he will create a committee to review our experiment and he will be the chair. In order to prepare for this review he suggested cleaning the language and being clear in the terms and descriptions of the configurations used for the experiment. We will use the figures that explain better the best figure of merit. Since Nathaly spoke with Chris the previous week getting some feedback from the questions we may encounter, she suggested a meeting to discuss those list summarized in the overleaf document. Steve Wood contribution: We need to prepare to support how we will control better than 1% all the systematics. Things mentioned in Karl's talk are good at mitigating some of them, but possibly not all of them. or conditional removal, don't need to have all issues removed already but do need to make sure we have a plan of how we're going to address it. Want to show that amount of effort going into systematics is going to be on-par with amount of effort going into the target Likely to be overlap between PAC40 (b1) ITAC and the conditional removal committee Steve thinks that swapping the two target cells will work for addressing most, but not necessarily all, of the systematic drifts Though PAC focused on the target polarization, the review committee may bring up additional aspects as well. An example of this happened to TDIS, where an issue was brought up in the 'conditionals removing' review even though it wasn't directly a PAC condition For ERR, need a well-defined scope of what needs to be built and done to be able to do it Ft Update from Allison: Still has a discrepancy in the cross-section she's working with, coming off by about a factor of ten Will work with Ellie & Nathaly later this week to try to figure it out Update from Nathaly: Will talk with Dave Benisch about beamline, and other folks at Jlab (including Dave Gaskell) Tighter schedule than normal this week, will be back at UNH next week Update from Ellie: Will work on setting up meeting with us & theorists, particularly Wim & Gerry and possibly Misak, to discuss their thoughts on target field orientation |
