Inside the Cells

Each cell contains the necessary components for pulsed field measurements. Here, one can see the helium fridge (blue) next to the magnet (inside the green box) and cryostat. The probe is inserted through the cryostat into the magnet.
The leads from your sample and probe are connected to the data acquisition instruments pictured here. The signal enters the lock-in amplifiers where noise is reduced before it reaches the digitizers and DAQ software. Also located here is a temperature controller to monitor the conditions surrounding your sample.
