Left Grenoble by car in the morning. Andrea, Alain, Alessandro. Reached the telescope at 20h30.

Tue 04/06

During the maintenance craned up again NIKA, installed. Warm impedance test: 20mbar/min at 3 bar

Start cooling down at 13h30.

Test with VNA at 300K:

figures: VNA scans at 300K (0-8GHz). Left: 1mm array; right: 2mm array.

Installed the electronics with the cables.

figures: NIKA installed again

We have also visited the back of the antenna and in particular the receivers cabin roof for possible installation of the NIKA-2 electronics. Space available is 80cm (H) x 200cm (Width) x 100cm (Depth). In order to have enough space to work, we will use a maximum depth of 60cm. The total COAX cables length if this solution is chosen is 6-8m.

figures: Cabin top, possible place for NIKA-2 electronics.
