The HTS-110 LN series provides an alternative to the cryogen-free mechanical cryocooler systems by using a liquid nitrogen dewar for cooling power. Engineered for optical surface analysis and materials science, this series reduces technical complexity while providing exceptional optical access and rapid-turnaround performance for a wide range of laboratory environments.

Superior Optical & Geometric Access

Derived from the market-leading LM series architecture, the LN series is optimised for the tight constraints of optical benches.

• Exceptional Viewing Angles: The low-profile cryostat design provides wide optical access, essential for integrated microscopes and laser spectroscopy.
• Large Room-Temperature Bores: Available in 38 mm and 80 mm diameters, accommodating large samples and third-party variable temperature probes.
• Flexible Siting: Connected via a flexible metal bellows hose, the magnet can be easily positioned in constrained laboratory spaces away from the dewar.
• True Multi-Orientation: The robust design allows the magnet to operate reliably in any orientation—vertical, horizontal, or tilted.

High Experimental Throughput

Designed for rapid data acquisition and minimal downtime.

• Under 5-Hour Cool-down: Achieve operating temperature significantly faster than mechanical systems, with a typical cool-down from room temperature in under 5 hours.
• Rapid Field Ramping: Efficient HTS coil design enables fast field sweeps (typically 0 to full field in <60 seconds).
• Low LN2 Consumption: Consumes less than 0.5 litres per hour during standard operation, minimising cryogen costs and dewar swaps.
• Integrated Vacuum System: The included vacuum pump handles both liquid nitrogen circulation and cryostat insulation, simplifying the system’s footprint.

Precision Engineering for Sensitive Environments

• Ultra-Low Vibration: By utilising continuous flow cooling instead of a mechanical cryocooler, the system produces exceptionally low vibration at the sample which is beneficial for high-resolution imaging and scanning microscopy.
• Compact & Portable: With a mass of less than 15 kg for the LN40 model, the system is easy to integrate into existing setups without specialised floor reinforcement.
• Active Protection: Dedicated monitoring electronics track critical operating temperatures and voltages for safe, quench-free operation.

Broad Scientific Applications

The versatile and budget-friendly design of the LN series makes it an ideal workhorse tool:

• Magneto-Optic Kerr Effect (MOKE): An ideal platform for characterizing thin-film magnetic properties.
• Optical Spectroscopy: Optimized for Brillouin light scattering and magnetic circular dichroism (MCD).
• Materials Characterisation: Hysteresis loop plotting and Hall effect measurements to characterize carrier properties in semiconductor materials.
• In-Line Process Monitoring: Compact enough for integration into chemical reaction monitoring and industrial testing lines.
