Introducing the XLDHe High Power System – Ultimate Cooling for 1 K Experiments
We are excited to announce the immediate availability of the XLDHe High Power System – a cryogen-free, helium-4 powered measurement system that delivers extremely high cooling power for experiments in the 1 K temperature range.
The XLDHehp is ideal for demanding applications such as spin qubit quantum computing devices, or single photon detectors for photonic quantum computers.
Ultimate 1 K Cooling Power
The XLDHehp gives you the flexibility and power needed to scale up experiments in the 1 K temperature range. The system utilizes helium-4 to generate extremely high cooling power between 200-700 mW at 1–1.2 K. It also includes a large main heat exchanger and powerful booster pump to maximize helium-4 flow. These features make it an excellent solution for larger experiments that emit more heat.
The default configuration of the system features two PT425 Pulse Tube Cryocoolers. For more demanding experiments, a version of the XLDHehp featuring 3 x PT425 Pulse Tube Cryocoolers is available delivering even greater cooling power at the 4 K stage.
Vast Experimental Capabilities
The system provides vast space for experiments, giving you greater application setup flexibility and the possibility to scale up your experiments in the future.
With a large experimental flange of 540 mm, the XLDHehp is available in configurations with either 2 or 3 section vacuum cans, providing experimental height options of 175 mm or 776 mm, respectively. This generous space supports a wide range of experimental possibilities, and ensures that the system will be ready for your future needs.
The XLDHehp with 3 section vacuum cans is able to house a 2 section still shield, bringing compatibility with cryogen-free magnets, and making the system ideal for spin qubit applications. A wide variety of magnets are available, including solenoid, vector, and split pair magnets.
The standard version of the system features six side-loading ports for fast exchange of experimental wiring, greatly reducing room temperature idle time. Large volume RF cabling is available as a high-density wiring solution. An additional 6 x KF40 ports (2 line-of-sight ports) provide plenty of options for experimental setups.
Fast Cooldown. Rapid Warmup.
The XLDHe High Power system features several fast turnaround options, making it possible to increase the number of experiments carried out by reducing the idle time between cooldowns.
Standard XLDHehp systems reach a base temperature of <900 mK in 12–16 h (depending on the size of the experimental space). Adding an optional LN2 Pre-Cooling Loop reduces the cooldown time to just 9 hours in the 2-section vacuum can configuration.
Additionally, a 4K Warm-up Heater Kit is available to safely speed up warm-up times. This can be especially beneficial when a large mass – such as a superconducting magnet or heavy experimental setup – is attached to the second stage of the pulse tube. The 4K Warm-up Heater Kit comprises 3 resistive 4K heaters, and is fully integrated with the system Control Software.
Ideal for Spin Qubit and Photonics Applications
When it comes to practical use, the XLDhe High Power System is ideally suited to spin qubit measurements.
Spin qubits – a promising, scalable quantum computing modality – depend on magnets for coherent control, manipulation and measurement of qubits. With its extreme cooling power, large experimental space, superconducting magnet integration, and extensive measurement infrastructure options, the XLDHehp delivers ultimate flexibility and power for spin qubit research.
The cooling power of the XLDHehp is also well suited to 1 K single photon detector applications, helping to reduce thermal noise, improve sensitivity, and provide a stable environment for the detection of single photon events. Applications for single photon detectors include quantum computing, quantum sensing, and quantum communications.
