[Alex, Daniel]

Alex finished the assembly of the SNSPD Dewer and vacuum parts. We then pumped out the vacuum system with the IDP 7 scroll pump to 8.7*10^-2 Torr (there is some systematic uncertainty with the pressure measurements with the pressure gauge and the magnet location). We enabled soft start on the turbo pump rack controller (see the wiki for how to) and plugged in the pump (while the rack controller wasn't powered). The soft start, which slowly ramps up the pump speed which is good when the pump has been off for over 3 months) remained on after this power cycle. We plugged in the included female 9 pin D-Sub with pins 3 and 8 shorted into P1 to bypass the interlock. We could then turn on the turbo pump. The pressure immediately dropped to ~10^-3 Torr and the turbo increased up its speed (not displayed by the controller) over ~15 minutes. The power draw by the turbo started at 10 W and peaked around 90 W. After these 15 minutes, the pressure was 1.6*10^-4 Torr and the rotation speed was 1167 Hz, the nominal value. The power drawn was 16 W.
