Customer pre-quote questionnaire - Chase Research Cryogenics

What operating temperature do you want your CRC cryocooler to work at?*

What is the minimum time you need your CRC cryocooler to stay cold (in hours)?

What heat load will your CRC cryocooler need to lift from the coldest stage (in microwatts)? If you don't know your load requirements give a brief description of what it is you need to cool.

Will you install the CRC cryocooler in an existing cryostat, or are you building a new cryostat for it?*

Yes, I have a cryostat I want to use
No, I am designing a new cryostat for it

Have you thought about how you will interface the CRC cryocooler to the 4K stage of your pre-cooler? If the answer is yes, please indicate which of the two options below is most like your system.*

You can see more interfacing options here.

Option 1: The entire CRC Cryocooler is in the 4K space
Option 2: The pump side of the cryocooler is in the 40k space
My system will not be like either of these options

Is your system like this?

Option 1: The entire CRC cryocooler will sit inside the cryostat's 4K radiation shield, fixed to the 4K plate. This means that the 'hot' pumps of the CRC cryocooler will require radiation shielding. The radiation shield can be designed to mechanically support the cryocooler, or, as in this picture, mechanical and thermal interfacing can be separated. In this configuration the electrical connector to the CRC cryocooler will be on the 'cold' side of the cryocooler's mainplate.

Yes, and I may need a radiation shield for my cryocooler
No I will not interface it like this

Is your system like this?

Option 2: The CRC cryocooler will be mounted through the 4K plate of the cryostat. This means that the 'hot' pumps of the cryocooler are not within the 4K radiation shield of the cryostat, and will not require a radiation shield of their own. In this configuration the electrical connector will be on the pump side of the cryocooler, i.e. below the cryocooler's mainplate.

Yes, and I may need a radiation shield for my cryocooler
No I will not interface it like this

Can you give us some more information about how you intend to interface to your cryostat? If you're not sure and would like our help please let us know.

And finally - will you need additional fixing holes in the mainplate of your cryocooler so that you can attach things like heat straps or cold table supports to it?*

Yes
No
Maybe - please discuss options with me

Please let us have your email address so that we can follow up with you.*

That's all for now! We are always happy to discuss your requirements with you, by Skype if that would be useful. Please let us know whether this questionnaire has been helpful.
