|
We spent most of the day looking at OLIS to find out why the "Ionizer Coil" keeps breaking down, we found
the following:
1. The FAN to cool R5 (ref: ISK4583D rev.7) a 25 Ohm 200W Resistor (2x50 ohm/100W ea.) was not ON, the nylon |

I updated 2 drawings that show the OLIS skimmers.
A. ISK4363D for the OLIS Skimmers BOP connections, we have 7 skimmers cables (6 wires per cable) going in
and 16 skimmers channel going out to Controls. |

|
OLIS Shutdown has been in progress for a week. IOS is vented, was swiped clean and opened. DB3 was craned out, a precision job. Note to whover reinstalls
this box: Request Lu Sun to do it. He knows exactly how to tension the ropes so that the seals are not at risk of damage. Upstream optics
in DB1 were also removed in the standard three sections. No problem removing them. Photos and commentary to follow. Bellows downstream and ahead of separator |

Supernanogan cart removed from Faraday cage to dock today. Some beam safety tests on FC6 in progress presently. FC3 was already removed for replacement.
Optics Photos: Lots taken; selected ones here as time permits.
3-Way Switch (DSCN7285.jpg & DSCN7286.jpg) looks pretty good. There is some discoloration on a downstream insulator, but far from worrisome. |

Preparations for rewiring the DB1/3 optics have begun. Sgan gas manifold work is in progress. Note: IOS:MP1 is scheduled for refit service shortly. We
received major rebuild kits a few days ago, one to replace the kit used when the previous MP1 failed last fall. It is not likely this pump requires it;
only the standard seal kit. |

| More materials prepared for optics refit. |

Partial disassembly of DB1 optics today. Shielding of insulators is definitely working and indicated for unshielded insulators. Discussion of possibilities
in progress. Wiring looks good, but one Kapton wire snapped at the connector upon disassembly (no force required). |

Wed Feb 3 16:30:02 2010, Damien Gallop, , , OLIS Shutdown began today
|
We prepared stuff last night. This morning we vented IOS to argon, then swiped. Clean. Lu and Ajit craned out DB3 for us. Nice job, as usual. We will
remove it and its neighbors to the ISIS Lab for refurbishing. OLIS Shutdown is scheduled to go until March 10th. |

|
The OLIS 1 week shutdown has been completed (WP 2015-04-13-1).
General-
Y-Box insulators were inspected and look good. Beamline optics were inspected. |

Two weeks of OLIS Shutdown have begun. The plan is to complete refurbishing this week and pump next week, with 36Ar+6 beam ready at the end of it. IOS
is vented and open. The Supernanogan cart is out, vented and open. Plasma chamber cleaning and refurbishing in situ are in progress. The IOS upstream optics
DB1-3 have been removed for refurbishing on the bench. |

| MCIS pumped overnight. Still coming down. |
|
Wed Nov 2 10:16:49 2011, Damien Gallop, , , OLIS Shutdown
|
MCIS pumpdown continues well. IOS optics coming along. DB3 installed last night and IOS is under vacuum very early. DB1/2 optics will remain out until
the end of the next-up MCIS run. |
|

|
MCIS pumped well overnight. Source development imminent.
Later... possible IOS intervention. Spin down turbos in anticipation... Meanwhile, MCIS pressure was at 7.8e-8 Tott at the start, and dropped to
7.4e-8 Torr immediately upon closure of MCIS:IV1. Note that IOS:IV0 remains open with interlocks bypassed. |
|
Fri Nov 4 09:41:32 2011, Damien Gallop, , , OLIS Shutdown
|
MCIS continues to pump well. IOS DB assembly planned for today.
Later... DB assembly complete and IOS under vacuum. Present pressure: 1e-6 Torr at ~18:00. All optics hold voltage. |
|
Mon Nov 7 09:58:17 2011, Damien Gallop, , , OLIS Shutdown
|
IOS pumped well over the weekend. Present pressure is 1.5e-7. MCIS pumps off
for setup.
Later... Supernanogan is online with better than 250enA of 36Ar7+ on FC6 presently ~17:00. Note: MCIS:TP3 is off by intention for this run. |
|
Tue Nov 8 10:02:54 2011, Damien Gallop, , , OLIS Shutdown
|
Supernanogan is online with 36Ar+7 on FC6 overnight. Looks good. Note: The source gas arrangement (enriched 36Ar) utilizes double buffer canisters and
calibrated leaks, and requires MCIS:TP3 off.
Controls is preparing to perform an IOSIOS reboot for the sake of new code for ILT:RPM8 or something like that. |
|
Wed Nov 9 11:40:35 2011, Damien Gallop, , , OLIS Shutdown
|
Supernanogan 36Ar+7 source development in progress. RF frequency scans are the agenda for today.
Later... Some good beam results and 300enA beam on FC6. Note: 5mm slits are in. |
|
Thu Nov 10 09:57:57 2011, Damien Gallop, , , OLIS Shutdown
|
Supernanogan on overnight with 36Ar+7 on FC6. Nice.
Today is the last day of scheduled OLIS Shutdown. Expect more source development today followed by a hand-off to ICR at some point. |
