1.2.2. Temperature

The chiller does not manage to cool enough. This happens mainly if the facility's water isn't
running or if the chiller itself is getting hot (either internal defect of the whole rack is too hot).

1.2.3. Flow

Water is not circulating fast enough in the circuit. Here are a few things to check
-
filters are clean
-
pipes are not pinched or bent
-
no extra length of small diameter (external diameter < 12 mm) pipe was added
If none of the above seems to cause an issue, one of the elements can be clogged. To remove
the blockage, stop the related system and reverse the water flow several times for one minute
at a time until the flow is back to normal. Be careful to flush the water and clean the system
afterwards according to the procedure of the start-up manual.

1.3. Deionising unit

1.3.1. Water flow

The water flow if indicated on the flow meter on the right if the front panel. If it is too low,
check the chiller as described in section 1.2.3.

1.3.2. Water resistivity

The resistivity should not drop below 0.5 MOhm.cm, the alarm sets off at 0.3 MOhm.cm. If it
does the deionising cartridge must be changed according to the operation note "How to
change a de-ionising cartridge".

1.4. High voltage unit

If the high voltage power supply of the Pockels cell has the "Failure" LED on, power it down to
let it cool down and check the cable connection to the Pockels switch on the Regen amplifier.
If the failure still appears, contact Amplitude for service.

2. No output from the Regenerative amplifier

This should be seen with the diode at 50 % or 53 %. The diode should not be set at nominal
power if the beam is not present beforehand.

2.1. Easy checks

2.1.1. There is something in front of the diagnostic cameras

The cameras are outside of the amplifier, it is easy to inadvertently put something blocking
the beam path.

2.1.2. Oscillator is not started

Check the oscillator status in the Magma 25 module – Main tab. The three first LEDs should
be on (note: there is a 30 sec delay check before the before 'Oscillator stable' turns). If the
oscillator is not running, and if there are no Safety interlocks listed below, set 'Laser diode' to
ON if it is not, turn the 'Front-end' key on the key rack unit, turn the key on the Front-end unit.
One can look at the oscillator's pulse train and the picked pulse by sending to an oscilloscope
the "Oscillator monitor" and "Pulse picker monitor" BNC outputs at the back of the Front-end
unit.
