 +==== Setting up the vibration isolation ====
 +
 +Before imaging, you will need to set up the vibration isolation of the SEM column.  This is currently a manual process which works as follows:
 +
 +  - At the back of the SEM you will find 3 translucent blue tubes, each ending in a tire valve adapter.  You will also find a bike pump ready right next to them.
 +    {{:equipment:zeiss-dsm-962:log:pxl_20250823_190224637.jpg?400|}} 
 +  - Connect the bike pump to the tube that runs deepest into the SEM, connecting to the front isolation bellows (this tube is split to connect to both front bellows at the same time).  This one has a small ball valve as the tire valve is broken.
 +  - Pump up the bellows to 2.9 barg.  After reaching that pressure, the bellows start suddenly moving quickly.
 +  - Immediately stop pumping and go very slowly.  You want the bellows to be roughly around the center of their extension range.  Release some air through the tire valve if necessary.
 +  - After pumping up the front bellows, attach the bike pump to the back left bellow.
 +  - Repeat the pumping procedure detailed above.
 +  - Finally pump up the back right bellow using the same method.
 +  - Over time, some of the tire valves may leak some air.  Just refill the bellows as needed.
 +
 +You can find more info in the [[equipment:zeiss-dsm-962:log#day_2025-08-23_q3k_rahix_ln_rob_2x_guest|Log Entry]] when we set up this system.  Be gentle with it and don't overfill the bellows.
