MCIS-
the Se was loaded into the oven last friday (21st). During the weekend the presence of 76Se +11 to +15 was verified.
NOTE- the oven p/s on the cart is broken. An attempt was made to remove it on friday. It may be possible to remove, if the rack it |

The remaining connections were done on the MCIS.
A piece of 1/8" teflon was installed between the back of the sputtering tube/motor and the HV cage.
Ray confirmed the cart power supplies (heater and sputtering) Epics page readouts for Voltage and Current are okay. The Heater p/s was left |

MCIS-
the cleaning has been completed. The oven assembly is removed and the gate valve closed.
The quartz tubes on the ground electrode have been installed with the larger diameter tube pushed as far downstream (toward the optics box) as |

Thu Nov 13 16:34:29 2014, Brian Minato, Other, Other, MCIS Update
|
The ethernet cable from the CPI TWT amplifier has been temporarily moved to the Alga 50W amplifier. The Alga had been experiencing loss of communication.
This has not been an issue with the CPI so this cable will be tried with the Alga. A signal generator is not connected to the Alga. |

|
The MCIS was vented with nitrogen yesterday. The Se oven was drawn back into the tuner. It was removed with the tuner and blanked.
The standard quartz window was removed and replaced with a ceramic, test window supplied by CPI. (p/n VWU2054). The system is currently pumping
down. |
Tue Jun 23 18:04:30 2009, Damien Gallop, Routine, General, MCIS HV conditioning to 20KV 
|
Supernanogan bias for this run is 16.32KV. After we were finished with source tuning, etc., we conditioned up to 20KV. Then beam was returned and 16O2+
tuned saved as 090623_1730.snapmcisfc6. Next step: Prepare MWS for dual operation. Source open now for source gas installation. Then Keerthi will
develop a daul-mode tune, where the B1A bender only need be switched on or off to run either the MCIS or MWS source. |

Tue Sep 15 16:09:31 2009, Damien Gallop, , , MCIS Development 17O emittance scans 13x
|
We noticed a double peak effect in the 16O3+ scan. I will set up the line for 17O3+ and see.
Scan #1: Double peak also visible.
Scan #2: Remove upstream slit altogether. Now profile is twice the size in the opposite direction of the double peak. |

Development and the quest for gold continue.
Later... Mass scans in region of 197Au33 A/q=5.97, with graph of all theoretically possible charge states in the same A/q region. The thing to
note in that last graph is how clean is the region (just left of A/q=6) where 197Au33 is predicted. |

Tue Sep 15 10:32:39 2009, Damien Gallop, , , MCIS Development 7x
|
So. We are preparing for a few days of Supernanogan development. The present run plan is to obtain good emittance scans for higher charge states of 16O,
17O and 18. We may be limited by the loss of MCIS:TP1, but maybe not.
Set up on nom 18kV tune based on last recent save: 090831_1104.snapiosfc6. MCIS HV tickled up to prevent extracted beam surges. |

|
The 16O3+ DRAGON run just finished. MCIS Development begins this morning for a few days. The goal is to install and characterize the new sputter ion
source.
Below are vacuum pics before and after closing MCIS:IV0. There was a bit of a spike during closing. All three turbos switched off. TP3 is down |

Thu Sep 16 17:06:22 2010, Damien Gallop, , , MCIS Development
|
A new sputter source was installed onto the Supernanogan. A wire of Au is installed in the source. Mass scans this morning with source at equipotential.
Source patched to MWS EE supply and biased to ~1kV tunable. That makes a significant improvement in intensity. Beam at FC6 is 197Au24+ presently. |
|
Fri Sep 17 14:02:29 2010, Damien Gallop, , , MCIS Development
|
Today's agenda: RF frequency scans and generally getting a feel for the new sputter source.
Mass scan plots in region of 197Au25+ attached below, taken with and without the sputter source on. Matlab post-processed pics to come shortly. |

Beam development started yesterday. Looks like the HERACLES run, which started Thursday,
ended yesterday morning. |

|
| Development continues in the search for gold. A=197 Present A/q=5.94, which suggests 197Au+33. It could also be a tail of 12C+2. We'll see. |

Mon Sep 28 14:16:47 2009, Damien Gallop, , , MCIS Cart down for TP1 Replacement
|
We are taking the opportunity to replace TP1 today. Edi Dalla Valle is on it. Also, Diagnostics has a WP in the queue for looking at the attenuators,
so we have prepared IOS for venting.
Later... Cart was removed from cage for access. Pump was replaced successfully, and all volumes are under high vacuum now (17:00). In the end, |

Tue Aug 18 11:16:16 2009, Damien Gallop, , , MCIS "PV" PLC trip overnight
|
Another in the on-going saga of MCIS:PV1 trips occurred again this morning. The operators recovered most of the vacuum devices except for the IM section
gate valves. We had an in-person discussion about them, the order in which they should be opened, and the existence of a hand valve in the IM roughing
line. An ION note is needed. |
|
Wed Jun 10 18:48:53 2009, Damien Gallop, Routine, General, Krypton source gas fitted
|
Krypton source gas teed directly into ion source. A Nupro valve and tee also added for 17O line. At present, the 17O gas bottle valve is closed. The
Kr bottle has an integrated leak, so this bottle is opened to the system now. Pumping in progress. Pressure is already <3e-7 Torr. I will restart the
source shortly. |

Tue Jun 30 10:30:17 2009, Damien Gallop, Routine, General, Initial development setup
|
Setup teething pains... The Start button on the emittance panel worked this time. But ICR called, requesting a few minutes more for Marco. No problem.
When I went to restart the scan, the button no longer worked. Restarting X11 made no difference. However, there is a significant update available for X11,
so I am installing it now. I perceive that it works, yes, significantly faster than its predecessor. Good, all good. |
