 Sun Dec 2 23:36:13 2012, Keerthi Jayamanna, Routine, General, 16O+2 is ready for tuning.
|
MCIS finished xenon development. MCIS is off and isolation valve is shut.
A new oxygen gas line is installed to microwave ion source via a hand valve neat PE.
Hand valve is tuned as a small leak so that the plasma can run with all other gas valves are shut.

During the last week we delivered 18O+2 from microwave ion source to Ritu.
Over the week end changed to 40Ar+2.
Ritu informed us 18OH2 is coming with 40Ar+2. |

|
MCIS TP1 is not running well. Needs investigation as soon as S1219 is completed.
Later... TP1 failed completely, and we are running without it. Starting late Saturday night, DRAGON began to observe a certain instability. We
correlated it to MCIS:COL0, which skims total current continuously. It is pretty evident that the source is now toggling between two adjacent plasma modes, |
