Back to the NIKA2 run 1 main page
September 2015, 24
The 2 1st trucks transporting NIKA2 hardware have arrived at the telescope, and have been unloaded.
The 3rd truck containing the cryostat and driven by Alessandro, Martino and Andrea will arrive on Tuesday 29 in the morning. Alain, Samuel and Johannes will also arrive on Tuesday morning.
September 2015, 29
Everybody has arrived at the telescope this morning: Alessandro, Andrea and Martino with the truck, Alain, Johannes and Samuel with the IRAM transport, with some Granada staff (Santiago, Juan, Dave, Gregorio, etc) who will help installing NIKA2.
There's about 2 tons of material to install. We have installed about half of it: compressors and dilution pump in the cable spiral room, automat (cryogenics control) and pulse tub cold heads on the wall in the receiver cabin, optical fibre switch, some electronics and computers in the control room, He pipes at intermediate stage, plug and test communication with these hardware.
September 2015, 30
1st big operation of the day: we have lifted the NIKA2 cryostat up in the cabin and installed it at its nominal position. 2nd big operation: we have installed the He pipes: from the instrument, down along the azimuth column to the cable spiral and then to the compressors. We have also plugged all the pipes, lifted the cryostat nose, lifted the polariser wheel, installed bars, rails, pulse tubes cold heads, opened and check the screens of the cryostat down to the detector holder frame.
