Operators: kdow seely ----

Reasonably smooth running. Some trouble injecting around 6am; after that BQMs tended to be a bit high (140 counts/mA for Top instead of 100) early in each fill. "Ears" in z spectra not very prominent, except downstream end of z from right sector.

Runs 2168-2174 taken (2170 is junk). 2171-2174 still being lr'ed. flr complete through 2168. charge done on all.

Trigger Supervisor Level 1 Accept (i.e. counts actual hardware triggers) added to scalers (11th column, 17th channel) during run 2165 (see elog entry).

Since 10:50, Ops tuning beam for reproducible ion polarimeter tune (BLAST on, transverse holding field off).
