| - | ====== Checklist after power failure ====== | ||
| - | |||
| - | <note important> | ||
| - | |||
| - | |||
| - | **Check both IGP Controller for the resonators R1 + R2** | ||
| - | * Current should be below 2 mA (both should show "HV ON" (green LED on) | ||
| - | * Check both USV for IGP´S | ||
| - | |||
| - | **Turn on the computers** | ||
| - | |||
| - | **Check Meerstetter TEC for R1 + R2 + ECDL** | ||
| - | * Green LED on? | ||
| - | * Check in the software //TEC Service v2.70 - R1//, //TEC Service v2.70 - R2// and //TEC Service v2.70 - ECDL Baseplate// on the ResLab-PC: | ||
| - | * How is the behavior of the temperature? | ||
| - | * Check both USV for TEC´s | ||
| - | |||
| - | **Check the air conditioner for the entire room** | ||
| - | * Is the air-conditioning system switched on? | ||
| - | * Is the V-belt (=Keilriemen) broken? | ||
| - | * What is the temperature of the draft (=Zugluft)? -> should be >20 °C | ||
| - | * Check the electric fuse (=Sicherung) on the third floor | ||
| - | |||
| - | **Check the H-Maser** | ||
| - | * All LED are green? | ||
| - | * Check in the Software //VCH// on the ResLabMobil: | ||
| - | * All values except for D2h must be green! | ||
| - | |||
| - | **Check the 914nm-laser** | ||
| - | * Light is on? Powermodule is on? | ||
| - | * TA stabilization is ok? | ||
| - | * Laserdiode is on? | ||
| - | * How much power is in front of the resonator? -> should be 70-100 µW | ||
| - | * What wavelength does the Wavemeter display? | ||
| - | |||
| - | **Check the 10 MHz reference and set all frequencies in the lab** | ||
| - | * GPS-Receiver is working? | ||
| - | * LED flashes orange/ | ||
| - | * If not Turn on the PWR switch until LED flashes | ||
| - | * Start the software //Net View// and connect the receiver (COM Port2) | ||
| - | * Rb-clock is working? | ||
| - | * Check the LED´s: | ||
| - | * // | ||
| - | * //1 pps sync//-LED has to be green | ||
| - | * //1 pps input//-LED has to flash | ||
| - | * Check the 10 MHz-frequency output with an spectrum analyzer, if there is 10 MHz. | ||
| - | * Check the 10 MHz distributor synthesizer | ||
| - | * Ext refernce //10 MHz direct// is working? | ||
| - | * Set correct values | ||
| - | * Check all other synthesizer | ||
| - | * Ext refernce //10 MHz direct// is working? | ||
| - | * Set correct values | ||
| - | |||
| - | **Check frequency comb** | ||
| - | * Laser and amplifier are on? | ||
| - | * Check LED´s | ||
| - | * Do the software //fiber laser// and //fiber comb control// work? | ||
| - | * Can you speak with the comb? | ||
| - | |||
| - | **Check the counter** | ||
| - | * Does the software //FXQE80// work? | ||
| - | * If not: Turn off and on the counter (cold-device plug disconnect and connect) | ||
| - | |||
| - | **Check the fiber Link to PTB** | ||
| - | * Turn everthing on, like ther spectrum analysizer | ||
| - | * Restart the PC in the Atom Lab | ||
| - | * Call them! | ||
| - | |||
| - | **If the temperature is normal again, then...** | ||
| - | - Stabilize the laser of R1 | ||
| - | - Turn on the Laserdiode | ||
| - | - Turn on the TA | ||
| - | - Couple the light into the TA | ||
| - | - Turn on the TA stabilization | ||
| - | - Lock R1 | ||
| - | - Stablize the frequency comb | ||
| - | - Lock Ceo | ||
| - | - Lock Rep | ||
| - | - Measure the frequencies with the counter: | ||
| - | - 914nm | ||
| - | - frep | ||
| - | - 10 MHz | ||
| - | - virtuel beat | ||
