January 14th 2014: Andrea Catalano come to the 30m to turn on the NIKA cryostat and checking the cool down remotely controlled from Grenoble (Alessandro Monfardini and Martino Calvo).

STATUS

9h30: Reboot of the PC NIKA and change the VNC forwarding on the router.

10h: Pumped the trap (J5=46mbar). Pumped the dilution circuit (until Jpi=3e-2mbar).

11h: Pressions stables. ZERO OF J1 IS -25mbar!!!

12h: Connected the leak detector. Residual pressure in the cryostat 6.6mbar.

12h15m: Optical alignment of the cryostat started.

12h30m: Impedance 18mbar/min at 3bar. It is maybe less w.r.t. the last run cryo (not clear from the old files). WE CONTINUE.

13h: Leak test: OK, in the 1e-9 range.Pumped ev18 for 15 minutes. It was well empty in any case. REMEMBER NOT TO TOUCH ev18 ANYMORE.

13h: Optical alignment OK.

14h: GREEN LIGHT for switching on the Pulse Tube. Mixture circulated for two hours at 3bar.

14h30m: Pulse Tube on with 900mbar.
