Minutes
Sean’s Talk on “Nitrogen Correction”
- Bogdon asks about the use of carbon foils, and was the air taken into account. (Sean did)
- Arun asks Gordon about partial pressure of Nitrogen (it is known) and does the distribution through the cell matter?
- Todd states that at operating temperatures we have an ideal gas.
- Bogdon states Less nitrogen means less background & we need the ratio of Nitrogen to 3He, which Sean explains how we only have Carbon data. (but only for GEN3 & GEN4)
- Sean presents what he thought to be very low percentages, but he stated it was just a first look.
- Bogdon asked about Quasi-Elastic cuts & how percentages are found. (Sean briefly explains)
- Gordon likes the first look but percentages are well below the 5% of GEn1 and there was talk about thinking about why this would be. Is it an error in code, assumptions, or something else?
- Xiaochao suggests a step by step look to dig further into the Nitrogen percentages to see if some insight can be gained.
- Arun asked if Carbon hole could be useful and Don pushed back due to high uncertainties incurred by beam position, width, and the raster.
Bogdon’s Talk
- How should we deal with low statistics and high changing polarizations
- Look at helicity. If polarization is stable then the “naive” (already used) method should be the same as the method he is looking at from the particle group.
- Gordon asked if Bogdon had done estimates on how his approach differs for what he (Bogdon) wants to use it for. He has not yet, since he has been busy in other areas.
- Discussions will be on going for this method.
“An amagat is a practical unit of volumetric number density. Although it can be applied to any substance at any conditions, it is defined as the number of ideal gas molecules per unit volume at 1 atm and 0 °C. It is named after Émile Amagat, who also has Amagat's law named after him."
