This week FC1 (Filter Cavity [mirror] #1) was installed in the @LIGOWA's new HAM7 vacuum chamber for the new @LIGO A+ Filter Cavity.
FC1 is a triple suspension mirror. This work was also installed in @LIGOWA's NEW "Mega Cleanroom"!

Here the HAM7 #vacuum chamber is partially opened up. The FC1 suspension is shyly hiding inside it's protective cover as TJ (Lead Operator), Travis Sadecki (Operations Specialist), & Rahul Kumar (Suspension [SUS] Detector Engineer) prepare for installation.

FC1 Uncovered!
This @LIGO Triple Suspension currently has a "dummy weight" suspended at the bottom, this "dummy" will be replaced with its mirror next! TJ is in this photo.

The #phyphox app from @rwth_phyphox gives you direct access to the output of many #sensors in your smartphone. Next time you have a long ✈️flight, quantify turbulence or just check on your phone when the toilet rush is over. (Warning: #scicomm #physics thread ahead!👇) 1/n
Your #phone is full of #sensors (microphone, camera, temperature, GPS, light sensors, magnetometers,…), including air pressure sensors and accelerometers. The pressure at cruising altitude is about 80% of the pressure at sea level. 2/n
That’s why your crisps package expands after take-off and the empty plastic bottle appears auto-crushed after landing. The pressure sensor can be used to estimate elevation when being on earth. But it is so sensitive it feels when airplane toilets are flushed. 3/n
