This morning we kept on working on the grounding of the laser lab by unpplugging the different devices that were plugged on the "flying" multi sockets and replugging them on the new ones installed last week. See the attached photos. Here below is the log of our intervention, indicated times are local times.
We had to switched off both the ML and the fiber amplifier. After the changes, everything relocked smoothly.
On Walid Chaibi instructions, we brought the signal PSL_PSL_FIBER_AMP_Pump_Imon_D2 to 2.415 A. It had been set at 2.405 A last week while its normal working point should be 2.415A. New values on the display 77.9 W 5.85A

To be noted that two devices are still connected to the old multi socket on the bottom of the rack: the signal repeateter on top of the rack and an artemis power supply on the bottom (see 3 last pictures). We would like to ask concerned people to know if there are any precautions to be taken before switching those devices off. In particular the artemis power suplpy that supplies many other devices: LB photodiodes, RF amplifiers for EOM and AOM, SL rampeauto...

From multi socket on the bottom of the rack to the new multi socket on the rack:
111000 RF generator used for the scan of the PMC
111220 diff2diff box 

112600 we put PMC_TRA as a trigger for the pmc instead of IBJM, we relocked the PMC and take a reference for AMP_DC and PMC_TRA

113015 we switched off the fiber amplifier

113500 we switched off the master laser and repplugged it on a new multi socket
114530 switched on master laser
114600 increased current in master laser
114930 reached the nominal values

Unpplugging of the following devices from the multi socket on top of the Faraday cage and repplugging on the new multisocket on the faraday cage (not connected yet):
115000 stabilized power supply for the monitoring of the fiber ampli security
115157 general power supply of the fiber amplifier
115450 artemis power supply that supplies pmc rampeauto and signals of fiber ampli
115510 oscilloscope used for pmc scan

115630 connection of the new multi socket
115646 switched on artemsi power supply for pmc and fiber amp signals
115820 power supply for the pmc monitor photodiodes unplugged and replugged on the new multi socket (right side of LB)

120630 fiber amplifier back to "new nominal" current:

120844 PMC locked

121330 Put back IBJM as a trigger for PMC rampeauto

122045 all PSL/INJ loops are closed

122550 ML noise eater OFF/ON to remove the 680 kHz line
