Phase Camera hardware Nothing really new, only summarising status 3 electronics boxes (dig. processing) ready ADC characterisation ongoing (need few days more) Then shipping to EGO site Prototype in EE-room will be replaced (main difference is mechanics) 2 PDs ready DC gain adapted Not tested, laser setup at Nikhef not yet operational Swap currently installed PD of PC1 Electrical splitter box ready Will be shipped together with other boxes Replaces prototype in EE-room Cabling (electrical and fibres) for PC2, PC3 are at EGO site Installation to be done in collaboration with Flavio Also 2 coaxial cables between EE-rooms and other rooms needed.

Software Not all channels showed up data in dataDisplay We have 22 ‘channels’ with power and phase info 11 demodulated PD frequencies, and 11 electrical reference frequencies Power and phase of a channel is transmitted as one word The power of the 11 ref. frequencies always showed zero, phase was non-zero The power info in the raw data packets on the TOLM network were not zero PC digital boards send out information -> display problem For long time I thought to be due to the Dictionary But at Nikhef, it works.. And now it (suddenly?) also works in Virgo, nothing changed in our code, maybe there was an update of dataDisplay? I will check regularly whether it remains OK Martin van Beuzekom TCS-PC meeting 13 May 2016

Next steps Next thing to get going for PC2/PC3 is the control of the mirrors via standard Virgo DAC channels For PC1 use we an external generator At the moment we do not yet have a DAQ-box at Nikhef Hence can’t test it Martin van Beuzekom TCS-PC meeting 13 May 2016
