Fri Oct 2 15:58:36 2009, Keerthi, , , 17O and Ne gases are now connected
|
A 1e-5 atm.cc/sec of 17O leak and a 1e-6 atm.cc/sec of neon leak are connected to the source through center tube of the RF transfer antenna.
Ne valve is open for upcoming CSB test. 17O valve is closed. All optics are set to A/Q=5.5. RF, EL and HV are off for the weekend since
no ISAC ops at night. |

|
Supernanogan is ready with 22Ne+4 for upcoming CSB run. EL, HV and RF are on. The anlyzing magnet and the other optics are set for A/Q=5.5.
A 2nA of 22Ne+4 is sitting at the FC6. If require more current, increase the RF up to 25W or change the frequency to 13.256GHz. |
|
Tue Oct 6 15:28:31 2009, Keerthi, , , OLIS A/Q changed to 5 (20Ne+4)
|
| Changed OLIS A/Q to 5 (20Ne+4) to satisfy the CSB and ISAC development changes. 8nA is sitting at the FC6 |

|
33S development is completed. A 3nA of 33S+5 can be produced with 10W of RF power and 2.5mm aperture.
If more beam is needed apertures and the power must be increased. There are some consequences for doing this.
MCIS optics and RF are off for the night. |

|
Microwave source is up and running.
Supernanogan: grounding rod is stuck, RF generator does not clear the interlocks (controls?)
LEBT: FC3 air leak, in is out, out is in |

|
| My first OLIS elog entry. |
|
Thu May 21 16:23:37 2009, Damien Gallop, Routine, General, 18O4+/8+ to TUDA-II declared done around noon
|
End of run diagnostics done. See ISAC elog. Supernanogan cart is already installed and at high vacuum. Prepare to run 17O from Sgan sometime over the
weekend. Today's agenda:
1. Close 18O bottle and gas valves. |
|
Fri May 22 10:50:06 2009, Damien Gallop, Routine, General, MCIS online with 17O3+ on FC6
|
The previous 18O4+/8+ run to TUDA-II finished midday yesterday. OLIS was prepared for 17O delivery from the Supernanogan source. Leak checking was done
last night. The big offender was a failing metal seal on IOS:TP7. The pump will have to be replaced. Meanwhile the pressure is sufficient for 20nA of 17O3+
with 2.5mm (middle selection) apertures inserted. Present agreement is to leave TP7 as-is for this run. |
|
Fri May 22 15:03:55 2009, Damien Gallop, Routine, General, Temporary fix on IOS:TP7
|
Vacuum Group applied a temporary fix to the lower body seal on IOS:TP7, which we found last night to be leaking. Edi tells me that similar seals have
failed before. It's an O-ring, not a metal seal. The fix now was to marinate the outside seam with silicon grease and wrap with Teflon tape. We'll see
how that improves the backing line after a while. |
