If you are present at a power-failure, prepare the Emergency-Power-System (in D320 Mg-Lab next to the electronics/chemistry cabinet) and get gazoline (Super Benzin)

At (severe/long) power failure

Set up the emergency power system (EPS) on the balcony room - (Parameters to turn it on: Choke: Turn off, Gas: Turn on)

Disconnect the marked power-cord (next to “Notaus”) from the power-plug and put it into the EPS. Now, the turbo-pumps and IGP should be save

If the turbo-pumps fail: Close the big valve below the chamber-table for the big turbo pump and turn off the big turbo.

Things to do after power failure

There are two power-failure situations. One, where a fuse or the Notaus in the lab has triggered the power failure and then one, which happens for the whole IQ/UNI. The later one needs an additional treatment.

Whole IQ/UNI power failure

Most probably the ACs will fail after a power failure

Turn off every device (Oscilloscopes, commercial systems etc) and all the power supplys in the “Stromschrank” to avoid uneccesary heating of the lab

Check if the AC is working again (call 4440 to tell them or wait for the next day until it's fixed).<hi #ed1c24> Indication for a not working AC</hi>: The red light next to the WC/KRb Office is flashing (but musn't)

If ACs are working again, turn on every single device again.

Checklist of devices

Vacuum

Check if all pumps are running and all pressures are ok

If pressures and pumps are ok (especially pre-vacuum and turbos) open the pneumatic valves (Next to the Lab-Door, there is a orange interlock. Press the reset button. You will hear the valves)

Open, if it has been closed, the big valve below the table at the big turbopump

S-MOT Laser

Turn on the Toptica controler (green button)

Check the temperature controler of 285

If a PID does not seem to work (e.g. Offset cant be set): Unplug it from power and replug it.

Triplet Laser

Turn on the Thorlabs TECs for the Laserdiodes (they turn off on a power failure)

Turn down the current for every laser-diodes (even when the controlers are still off), turn the controlers off and set the short button to short

Reenable the powersupply for the LD (in the Stromschrank): Orange interlock (Press the reset button)

Turn on each laser controler. Then un-short the diodes. The ramp up the current

If a PID does not seem to work (e.g. Offset cant be set): Unplug it from power and replug it.

Wutz

Turn on the Toptica controler (green button) - If it does turn off itself: Wait 15 minutes for the TECs to settle and try aganin.

Turn on the EOM-Synthesizer (located on bottom of Dipole-Rack) and set it to the correct frequency (written on the device - Recall, 9, Enter)

Monitor for Wutz/Clock-Laser: In the menu, go down to PIP (Picture-in-picture) and press right: It should enable the Wutz cam on that monitor again

Lattice Laser

Check if the Meerstetter for the TiSa is working (green LEDs)

If a PID does not seem to work (e.g. Offset cant be set): Unplug it from power and replug it.
