[Sneap] Vibration attenuation

[Arthur W Haberl]

We did have a little bit of success by placing lead bricks on the intermediate piping, but this probably won't do much if your pump is right on the chamber.

  Greetings!

   

  We are now trying to do some irradiation of a very sensitive material and we are following the creep rate with an extensometer.  However, due to the fact that we have cryo-pumps installed in the chamber and on the beamline, there is a small vibration coming from the cryopumps that we need to get rid of.  Aside from moving to a different pumping system, do any of you have any experience/suggestions about removing the vibrations in the chambers or beamlines?

   

  Thanks you ,

   

  Ovidiu
