Dry Room-Temperature Bore Superconducting Magnet

The room-temperature bore superconducting magnet can be integrated with cryogenic devices, spectrometers, vacuum high-temperature furnaces, reaction apparatus, crystal-growth equipment, and microwave equipment for applications such as thin-film growth under high fields, electromagnetic transport measurements, gyrotrons, infrared THz, microscopic magneto-optics, STM, AFM, ESR/EPR, NMR, neutron scattering, and X-ray studies.

Examples：

1、A compact 9T room-temperature bore superconducting magnet matched with the Qcryo-S-500 cryogen-free cryostat and integrated with a gas-membrane pressure-regulated diamond anvil cell realizes a low-temperature, 9T high-field, high-pressure microscopic Raman measurement system, with additional high-pressure electrical transport, Hall, and susceptibility measurement capabilities.

2、Two room-temperature bore superconducting magnets matched with Qcryo-S-100 cryostats provide sample holders with 5 degrees of freedom for infrared THz experiments.

3. A 14 T room-temperature bore superconducting magnet matched with a 1.5K top-loading cryocooler provides a 65mm sample tube ID, a VTI base temperature below 1.45K, and a He-3 insert reaching below 270mK.

4. The split-type top-loading cryocooler (composed of a helium-recirculation cryogenic system (Qcryo) and a top-loading cryostat) features ultra-low vibration below 10nm. Its compact tail inserts into the 100mm room-temperature bore of a 9T superconducting magnet, making it an ideal cryogenic high-field platform for micro-area magneto-optical spectroscopy, confocal microscopy imaging, NV centers, and scanning probe microscopy (STM/AFM).

3.Superconducting magnet with 14T RT bore, matching with a 1.5K top-loading refrigerator, sample tube ID：65mm, base temperature:<1.45K, base temperature of He-3 insert: 270mK. 

4. The cryogen free split type top-loading cryostat(Qcryo-SV-100）with 10nm nominal vibration level. The compact tail is inserted into 9T superconducting magnet with 100mm RT bore for near-field optics and magneto-optical experiments.
