Hi All,
I need some basic info of He closed cycle cryos..(like working principle, etc)..
I have a compressor, which compress He gas and passed into a cryo's coldhead. So He gas expands in side the coldhead and cools the coldhead..then it again passes into compressor..so the cycle repeats..
I just want to know why and how vibrations are produced in such cryo (i.e., in coldhead) ?
[The compressor and coldhead are connected via tube, so i think vibrations are not from compressor!]
Is there any clever way to damp these vibrations ??
If i am correct there are no moving parts in coldhead !?
Does any have some schematic sketch of coldhead or cross section of a coldhead..i searched the internet..but dint get any idea! or what is inside coldhead..
thanks for your help
