No dilution chiller required! This mk class cryogenic strong magnetic field platform is opticallyelectrically measurable!
In recent years, with the rapid development of quantum technologies such as quantum computing and quantum communication, there has been a surge in demand for mK-class cryogenic strong magnetic field measurement equipment, one of the key experimental devices in this research field. For various reasons, scientists are asking, "What other proven commercialized cryogenic strong measurement platforms are there besides dilution chillers?" German quantum technology newcomer Kiutra has the answer!

After a long period of technology accumulation, since 2020, Kiutra Germany has relaunched its mK-class multifunctional ultra-stable extreme cryogenic system based on a new revolutionary adiabatic demagnetization technology. The system has an unprecedented long-time continuous cryogenic operation mode, users can choose the electrical measurement and characterization system with the feature of "ultra-fast sample change at cryogenic temperature", with up to 5 Tesla superconducting magnets, rapid electrical characterization of a large number of samples at a minimum of 100mk at cryogenic temperatures; you can also choose the nanometer vibration level of optical characterization A very low temperature optical characterization system with up to 3 Tesla superconducting magnets can also be selected to achieve fine optical characterization in a fully free optical path at very low temperatures down to 300mk, with low vibration and strong magnetic fields.
Kiutra's technology was listed by The Quantum Daily as one of the 31 companies in the world that can provide hardware support for quantum computing as soon as it was launched, and to date it has quickly provided related products and services to more than a dozen quantum research customers! Now let's take a quick look at Kiutra's mind-blowing technology!
The system adopts a continuous cryogenic operation mode, providing a continuous extremely low temperature environment as low as 300mK. The system can also provide a 3 Tesla superconducting magnetic field to meet the measurement needs of cryogenic magnetic field spectroscopy, and it is a system with an excellent all-free optical path for optical research at extremely low temperatures and strong magnetic fields. The equipment has a compact structural design, with the cryogenic sample chamber and all control modules integrated in a removable cabinet. The fully free optical path enables easy and arbitrary excitation and signal collection of the sample, and the system's built-in vibration damping design achieves nanometer-scale ultra-low vibration without the need for an external optical table. The ergonomic design of the system makes it easy to change samples. The special cabinet-integrated cryogenic platform design allows for the pre-integration of complex external experimental devices, greatly reducing the difficulty of operation for users of complex experiments.
Technical features of the 300mK very low temperature, low vibration, full free optical path optical characterization system:
1) Temperature range in continuous low temperature measurement mode: 300mK-300K
2) Ultra-low vibration: <100nm (peak-to-peak)
3)Full dry cooling, no need for liquid helium, no need for He3 gas
4) Magnetic field option: sample area magnetic field 3T
5)Free light path Sample cavity diameter: >20 mm

300mK very low temperature, low vibration, all free light path optical characterization system
In addition to the extremely low-temperature, low-vibration, fully free light path optical characterization system, kiutra's mk-class very-low-temperature electrical characterization system, which allows for rapid sample exchange at low temperatures, has also been highly acclaimed.
The system is optimized for quantum information, low-temperature superconductivity, traditional magnetism, etc. The lowest temperature is up to 100mk, and it adopts fully automated sample transfer device, which supports sample changeover at low temperatures without warming up the machine during sample changeover, the sample can be taken out and switched in a few minutes, and the new samples can be reached the ultimate low temperature in three hours.
These landmark technologies have been praised by researchers and have greatly facilitated customers, especially for rapid characterization and screening of large numbers of samples.Kiutra has been designed to address the diverse needs of electrical measurements by integrating up to 4 RF channels and up to 40 DC channels into the system. It can also be equipped with a 5T magnetic field for electrical measurements in magnetic environments.
