Notes: For items in blue, there is a macro that can be run. Macros are located in the PEP II characterization panel (off the PEP II Application Packages panel.)
RING CHARACTERIZATION
*0 - Setup SCP for data taking:*Macro SETUP SCP LER (HER): It sets up dispersion steering and buffer data acquisition for MIA. It creates a single bunch private BPM definition (#1) and enters it on POWER STEERING panel. 0.0 - Create PHYSICS_DATA

0.4 Make sure that the correct machine model is loaded. (Use design model)
1 -While still colliding - Configuration and orbit save, into NORMAL, at high luminosity: Macro MAGNET AND ORBIT SAVE: It saves magnet configurations. Default title is "Rings Char. <numBuckets> buckets. <numBuckets> is EPICS DB number of buckets) 1.0 - Stop GOF button macro(s) if running.1.1 - Save Normal magnet configurations: HER, LER, INJH and INJL. Save HER and LER orbits (bunch train BPM def.)
...
1.4 - Save zero current configs for both rings.
2 - Dump and refill one single pass into each ring (about 300 on 600 mA). 2.1 Save 1st-turn orbits: *2.1 - Save first turn orbits. (DR12 - PR10 e- and DR02 to PR08 e+) *3 - Scan ? in X,Y,U,V with optimized tunes: 3.0.1 --Optimize HER/LER tunes on luminosity. One optimization pass per tune. 3.1 - Print spectrum analyzer with markers at peaks with tunes set for Cap Sigma scan.
...
3.5 Make sure beam-beam scan files have been saved.
4 - 1.5 mA each ring in a single bunch; non-colliding. (default*: bunch 0 in HER, bunch 400 in LER).*Tune frequencies (Hz)| 10/4/2005 | 2/1/2006 |
LER: X 75088; Y 80197 | X 71656; Y 80337 | |
HER: X 70306;Y 86150 | X 71769; Y 84969 |

4.0 - Calibrate single bunch. Calibrate, refine, check counts, make public. (If needed)
...
5.0 - Restore 5.1 Turn on FFBK, TFB, Tune tracker, LFB and LGDW.
