LHRS Production Run List
From Hall A Wiki
- These run sets below have been checked rigorously for quality:
- Beam trips
- Gas Cherenkov: one photoelectron and main photoelectron ADC peak and TDC peak stability
- E/p electron peak stability (for a given momentum)
- VDC <math>t_0</math> peak stability

Major Kinematic Settings
- This section contains the run lists for negative or positive polarity, binned by the LHRS momentum setting. No distinction is made concerning the orientation of the target spin.
- Lists in red still need data quality checks, unless otherwise noted.

Polarized Target Run Lists
- This section contains run lists binned by the LHRS momentum setting and the orientation of the target spin.
Target and Beam Information
Target Polarization Changes
- Below are the various points at which the target polarization was changed.
- The run range defines the range in which a given target polarization orientation is valid (limits included).
- The times below refer to the start-of-run times for the first and last runs of a given target polarization.
- The target (polarization) orientation is with respect to the beam. <math>270^{\circ}</math> means that the target spin is pointing towards BigBite (i.e., beam-right when looking downstream). <math>0^{\circ}</math> means that the target spin is aligned along the direction of the beam (i.e., downstream).
