Slides
Accidentals in Compton reconstruction
Primakoff Yields and Eta Angular Distribution
Minutes
- Eta distributions
- Drew's slides with eta yields and angular distribution: eta_yield_slides_05_03_19.pdf
- Next week, will provide more detailed plots with progression of individual cuts and their impacts on the distribution.
- The angular distributions still need to have accidental and empty target subtractions applied.
- CompCal Calibrations
- Sasha showed that the CompCal energies from reconstructed compton events are shifted by up to 200 MeV. We will need to develop a procedure for calibration.
- Potentially we can use compton events for energy calibrations in addition to the snake scans.
