Using The CryoLab MSGyou can cryocool SQUIDs to below their critical temperature. Both cool-down (< 30 min.) and heat-up (< 20 min.) of your SQUID is extremely fast and controlled. Using a special SQUID sample carrier it is very easy and secure to prepare and install your sample. Measurements can be done fast and in a plug-and-play manner. This video will explain all the details about the CryoLab MSG for SQUID measurements.
Additionally to the CryoLab for laboratory measurements, Kryoz also offers semi-customised solutions for using your SQUID application in-field.
” The CryoLab MSG is a very promising technology for cooling of high-Tc SQUIDs in practical applications. “
Ass. Prof. A. Kalaboukhov, Chalmers University of Technology
The CryoLab MSG can cool down samples to 75 Kelvin in a plug-and-play manner. The vacuum housing can be either stainless steel or a plastic. Fully customised vacuum housing is available on request.
All connections required for the cooling, vacuum and SQUID sensor readout are made via quick connects.
A SQUID is connected to the CryoLab using a SQUID sample carrier to which all electrical connection can be made (soldered or wire bonded). Four connections are available for the SQUID.
The cooler platform without a SQUID attached. All protection around the cooler is made from plastic material which is SQUID compatible.
Mounted carrier with SQUID.
Once the SQUID is connected (glued) to the carrier it can be attached to the cooler (e.g. using silver paint).
At the bottom of the protective ring a cavity is situated to place a small feedback or input coil.
The CryoLab MSG is compatible with the SQUID Electronics from Supracon and Magnicon. Compatibility with other SQUID electronics is available on request.
The read-out device of the SQUID electronics system is simply slit into the back of the system where it is internally routed to the carrier of the mounted SQUID. This way the distance from electronics to SQUID is minimized. Both the cable from the flange to the slider and the carrier PCB are shielded and twisted (in pairs) to minimize noise.
