Kinematic names (d2n)
From Hall A Wiki
The standard kinematic names used in the run database are constructed according to a few simple rules:
- If the name begins with the letters pos, the LHRS is set to a positive polarity. Otherwise, the polarity is assumed to be negative.
- If the next character is the number 4, the beam energy is 4.7 GeV (that is, the standard 4-pass beam energy). Otherwise, the beam energy is assumed to be 5.9 GeV (5-pass).
- The next character is a capital letter (e.g. A) which indicates the momentum setting of the LHRS. The table of momentum settings is below.
- Finally, the digits that follow the capital letter (e.g. 0, 90, 270) indicate the spin orientation of the target. 0 degrees corresponds to longitudinal polarization; 90 and 270 are transverse.
