[Sneap] Vibration attenuation

I would try strapping lead bricks to the cryo head.

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
