Tue Mar 1 16:57:34 2022, CB, LV, PMH, New run
|
Beam issues due to too long storage time in the last hours. Motors moved out and not moving.
Decreased storage time to 70 s. Seems OK now. Restarted motor movement as before
Started new run R86 |

New run R84
Attempting to sync pneumatic movement with ring. Still see something on t out -> p out
Command to move out was being given relative to the wrong time. |

just FYI: current positions saved in files are x=1000 and y=-750. this information is good in case of crash.

Servo motors moved to fully out position as some work on the beam was neccessary. Beam injection had dropped from ~9e7 to around 1e7. Potentiometer
reads 19.10 mm. |

Tue Mar 1 04:07:31 2022, JM, EM, Temperature cycle
|
Have been unable to achieve decent target density with temperature cycling so far. Will attempt to go up to 300 k and back down to around 115 k which
proved successful in previous shifts. |
