- | Go into vacuum pump shack. Flip on power switch for pump (wait for blower to go on) Open valve slowly (parallel to pipe means open) Note if fan cords are plugged into wall outlet to keep pumps cool. Note oil temperature when you start up. Oil temps below 15º C make for a labored start. There is currently a block heater on the north side of the pump and a space heater on the south side. Inform Larry if the oil temp is low and the heaters did not run to bring the temp up before starting.\\ | + | Go into vacuum pump shack. Flip on power switch for pump and wait for the blower to go on in about 6 seconds. |
- | Go into lab building, check pressures on Vacmon display. If pressure is higher than 100 torr in any of the lines, pump those lines only one at a time. Open valve a little, then come back to open fully. When all lines to be used are well below 100 torr, open all those valves. The final pressure should be 0.5 - 1.0 Torr in each line. The pump will normally bring all 6 lines down to .2-.3 Torr. The S1 and S2 lines leak the most during the day and will read the highest in the afternoon when you return, usually between | + | Go into lab building, check pressures on Vacmon display.

Click TV [ON] to open the camera window and click [M10AL] to change view to the M10 alignment view, click [M7 open] to open the M7 mirror cover. Center bright spot in beam on the black reference spot. (Note that S2 has a double spot in the center and a single spot to the lower right. The double spot is the correct one.) You may need to adjust the IRIS or the TV brightness to see the bright spot well. [BEAM] cycles the iris from open to closed and gives a good idea of where the center of the spot is. To adjust the position, use Pico 2 to select, for example, E2M10 → [MOVE] (use large steps ~ 100). Note that the up, down, left, and right buttons do no correspond to the actual directions the spot will move.
