Facility Features, Working Principle and Specifications
Facility Description
Cryostat model : attoDRY 1000
Base temperature: 3.5 K
Sample temperature: 4 K (variable up to 70 K & above)
Superconducting vector magnets : upto ±1 Tesla in X, Y, Z direction
Excitation laser : 532 nm (0 - 40 mW)
Brightfield & magnetic field imaging possible
Microwave measurement : 12.4 MHz - 6 GHz
Per pixel sensitivity : 1 - 5 µT/√Hz
I-V measurements are also possible
Spectrometer : Andor Kymera 328i
PL measurements are also possible from 4 K to 70 K
The system is cryogen-free cryostat capable of reaching temperatures as low as 4 K and magnetic fields up to 1 T. It utilizes pulse tube technology for cooling without the need for cryogenic liquids, minimizing vibrations and allowing for easy sample exchange.
Pulse Tube Cold Head: Drives the cooling via gas compression and displacement.
Sample Vacuum Space: Providesisolation and thermal coupling for the sample.
Outer Vacuum Space: Enclosesthe sample vacuum space, providing an additional insulation layer.
Compressor Unit: Provides high-pressure helium to the pulse tube.
Overpressure Valves: Ensures pressure safety in both the inner and outer vacuum chambers
