AGENDA

Presenter 05/10/2021, 9:30Am ET
Minutes:
  • The PAC has asked for a wiki page where we will organize the material that probes if the conditional is fulfilled. Therefore, we opened the wiki page here: https://hallcweb.jlab.org/wiki/index.php/2022_JLAB_REVIEW It will focus in two aspects: i) the tensor polarization that will be achieved under beam conditions is 30% and ii) how the polarization will be measured.

The documents supporting the background and how the experiment will address the conditional will be posted there. Nathaly will organize the wiki page.

  • One of the questions that came up in the meeting with Chris: what is needed to optimize the polarization measurements from now to when the experiment runs? Dustin will make a slide summarizing the details of: i) List of needed equipment, ii) optimization work and ii) man power. Basically, the systems need to alternate and attenuate between hole burning and phase modulation (between absorption and dispersion).
  • There was some discussion about the new technote from Dustin about deuteron lineshape analysis. Ellie presented some questions about the population plots in the technote, especially related with the eta and phi terms. Dustin and Ellie will take this issue offline.
  • Next meeting will be on Friday May 20 at 10 am.


Attendees:

Dustin Keller, Karl Slifer, Elena Long, Allison Zec, Narbe Kalantarians and Nathaly Santiesteban


Presenter 05/10/2021, 9:30Am ET
Minutes:
  • The simulation used by Narbe was SIMC. He had an older version of the Fortran code and the input files specified the packing fraction, materal, thickness, among others. The cross section weighting was probably done with F1F209. The simulation lives in UVa and we will try to get access in the following week.
  • The email to the PAC (Bob) was send, there is no response yet.
Attendees:

Karl Slifer, Elena Long, Allison Zec, Narbe Kalantarians and Nathaly Santiesteban


Presenter 05/03/2021, 9:30Am ET
Minutes:
  • Questions were raised about the best simulation package to prepare for the experiment. Right now, Allison is working in the Geant4 package, but it does not have the Hall C spectrometers. However, it has the structure of the g2p target. It seems that implement the Hall C spectrometers is going to be difficult.
  • To start addressing the best simulation package, we will invite N. Kalantarians for our next meeting. Since he has previous experience in some studies of this kind https://www.jlab.org/conferences/tensor2014/wed-pm/rondon.pdf
  • New weekly meeting will be every Thursday at 9:30 am
Attendees:

Karl Slifer, Elena Long, Allison Zec and Nathaly Santiesteban


Presenter 04/27/2021, 10:30Am ET
Allison Zec Geant4 Simulation Update
Minutes:
  • Meetings with Chris Keith on Thursday (April 28) at 10 am EST.
  • Allison has a working geometry of the simulation. At the moment, the g2p target is on place. The spectrometer in place is the HMOS and there is some access to virtual detectors. The implementation of the tensor target, along with the geometry and the full hall C spectrometers have to be done.
  • Dustin will like some feedback in the most recent paper.
Attendees:

Dustin Keller, Karl Slifer, Elena Long, Allison Zec and Nathaly Santiesteban
