CryoVision software package and LabVIEW control VIs
The software package includes LabView subVIs to read or read/control current sample temperature.
Measuring the critical temperature of an YBCO thin film.
In this example we will cool down an YBCO sample (substrate 5 x 5 mm) and measure its critical temperature.
Attach sample to a carrier.
Connect the sample to a CryoLab Carrier and make the required electrical connections. In this example we used bond wires. You could also use soldering. Detailed information on how samples are loaded can be found here.
Attach carrier to CryoLab.
Once the sample is connected, the carrier can be attached to the CryoLab. All electrical connections are now rerouted to the back of the system where you may connect your preferred DAQ system.
Attach read-out hardware.
To measure the resistance of the thin film we used a Keithley multimeter which is directly connected to the CryoLab .
To start a measurement, simply set the temperature and start cooling. Depending on the used CryoLab type, the lowest temperature you can set is 90 Kelvin or 75 Kelvin.
All data can be logged with LabView using the included Sub VI software and CryoVision.
