Entry number 123321

owl shift run summary



(1) Shift started in kinematic 11 configuration.  We will stay in this config until the 0900 in the morning.  

(2) After discussions with swing shift, we found that the T1 rate as read out by the left arm was unstable. 

The right arm readout of the T1 rate is stable.  See Bob's assorted entries

(halogs 123245, 123249, 123266) for more details.

(3) Later on, we noticed instabilities in the T7 rates. see halog entries 123285, 123290, 123291, 123306

(4) The apple pie was great!

Other than that, stable beam & smooth (we think...) data taking!!
