Owl Shift Summary



Taking production.  No plans to do a profile scan.

"Equilibrium" temps of Left septum coils appear higher since yesterday.  HALOG 159555 and 159582

slug 28 (IN)  [final]  = 597.3 "ok" kilopairs = 2.236 C

IHWP flip to OUT.

slug 29 (OUT) [so far] =  75.3 "ok" kilopairs = 0.282 C

Charge Asymmetry widths are about a factor of 2 smaller now than compared to before the spot move.

An ABU Story (159584)
