| 1010 | Turbo pump failed, looks like the IVC is back up to 1atm. |
| 1040 | Valve out turbo and restart it, Matt has confirmed that it has its own roughing pump |
| 1043 | Pump out IVC with scroll pump again |
| 1052 | Scroll on IVC = 0.16 mbar, valve out scroll pump and turn off, will let the IVC sit and see how much it goes up |
| 1149 | IVC stable at 2.2 mbar, seems reasonable. Pump down again with scroll pump |
| 1157 | Tried switching over to turbo, the pressure went down to ~40 ubar but after valving out the scroll pump it slowly started increasing. The turbo pump makes a slightly noticeable high pitch sound and reads the warning F097, is this the usual warning? |
| | Isolate IVC for now |
| 1223 | Try pumping out just the pump manifold, starting with scroll pump and switching to turbo |
| 1225 | Turbo seems to be running fine, already down to 0.25 ubar |
| | The problem is likely to be with the indium seals then |
| 1557 | Turbo valved out, IVC at 1.4 mbar. Start scroll pump |
| 1603 | After 3 minutes, pressure on the trubo gauge is < 1e-1 mbar, so switching to turbo , but keeping scroll still ON since turbo might not hold up because of the leak |
| 1612 | Turned off scroll pump, IVC at 1.9e-3 mbar |
| 1616 | When I open the line to the Leak detector, the turbo gauge starts to read higher and went up slowly to 4e-2 mbar. I close the valve to the leak detector and turned on the scroll pump to stablize the pressure. During this time, leak detector made a jump from 1e-12 to 4e-8 and back to 1e-12 mbar L/s |
