Coulombs So Far
- We are currently on Slug # 27 (IHWP OUT).
- Coulombs taken in all so far: 165.5 C as of Tuesday 09:00
10/20/2009.
Concerns
- Please always check online hists and compare them to the reference
ones.
- If you find something strange or wrong, please HALOG it so that the
expert can check it.
- Target Operator, please always check target PID system and strip
plots to make sure all the systems work.
- The cryo flow rate around 25.2g/s and JT value is around 55.5
since this is better for Lumi widths.
- The flow rate and JT value setting are sensitive to the outside
temperature. Hence the settings may change from morning to evening.
- Please be patient when you adjust the JT value since it may take a
few minutes to make the cryo flow rate stable.
