Overview
The PHYSIKE Acryo-1.5K is a high-performance, closed-cycle cryocooler engineered for demanding low-temperature experimental environments requiring stable, continuous operation at base temperatures down to 1.5 K. Utilizing a dual-stage Gifford-McMahon (GM) or pulse-tube refrigeration architecture—configurable per application requirements—the system achieves rapid cooldown from ambient to sub-2 K in under 12 hours, with typical hold-time stability of ±5 mK over 24-hour periods under nominal thermal load. Designed explicitly for sample-exchange flexibility, the Acryo-1.5K features a vertical cold-finger architecture with a top-loading sample chamber, enabling tool-free access to the cold stage without breaking vacuum or compromising cryogenic integrity. Its modular mechanical design supports integration into ultra-high vacuum (UHV) systems (<1×10⁻⁹ mbar), electromagnetic interference (EMI)-sensitive setups, and vibration-critical applications such as scanning probe microscopy and quantum transport measurements.
Key Features
- Base temperature performance: ≤1.5 K at the cold plate (with optional 3He sorption stage or pumped ⁴He bath extension)
- Configurable refrigeration core: GM or pulse-tube options, with cooling capacities ranging from 500 µW @ 100 mK to 2.5 W @ 4.2 K
- Low-vibration engineering: Optional active/passive isolation packages—including suspended cold head mounts, decoupled compressor units, sand-damped support frames, and pneumatic active vibration cancellation stages—reduce RMS displacement to <50 nm below 10 Hz
- Ultra-clean sample environment: Indium-sealed sample chamber compatible with He exchange gas, UHV bake-out (up to 150 °C), and differential pumping capability
- Customizable optical access: Multi-window configuration supporting simultaneous transmission across γ-ray, X-ray, UV–Vis–IR–THz spectral bands using Be, V, Kapton, Mylar, sapphire, CaF₂, and ZnSe substrates
- Comprehensive electrical and signal feedthroughs: High-density vacuum penetrations including multi-pin D-sub, SMA/K/V-series RF connectors, triaxial BNC, fiber-optic ferrules (FC/PC, FC/APC), and gas-inlet ports for controlled atmosphere studies
Sample Compatibility & Compliance
The Acryo-1.5K accommodates a broad spectrum of sample geometries and mounting protocols, including standard PUCK, LCC, DIP, and custom-machined carriers for electrical transport (4-probe, Hall bar), optical transmission/reflection, thermal conductivity (3ω, steady-state gradient), specific heat (relaxation calorimetry), dielectric spectroscopy, and photovoltaic characterization. All vacuum components conform to ISO-KF and CF flange standards; helium-compatible seals meet ASTM F2298 specifications for elastomeric low-temperature sealing. The system supports GLP-compliant operation through optional audit-trail-enabled temperature logging (IEC 62443-3-3 compliant firmware) and can be validated per ISO/IEC 17025 requirements when paired with NIST-traceable calibration sensors.
Software & Data Management
PHYSIKE provides the CryoControl Suite—a platform-independent application (Windows/Linux/macOS) supporting real-time PID tuning, multi-channel temperature and pressure monitoring, programmable cooldown/ramp sequences, and automated vacuum interlock management. Data streams are timestamped with microsecond resolution and exportable in HDF5 and CSV formats for post-processing in Python (NumPy/Pandas), MATLAB, or LabVIEW. Optional FDA 21 CFR Part 11 compliance package includes electronic signatures, role-based access control, and immutable audit logs for regulated R&D environments.
Applications
The Acryo-1.5K serves as a foundational infrastructure platform across quantum science and advanced materials research: quantum bit (qubit) coherence testing in superconducting and spin-qubit devices; low-noise microwave characterization of kinetic inductance detectors (KIDs) and traveling-wave parametric amplifiers (TWPAs); far-infrared and THz time-domain spectroscopy; synchrotron-based X-ray absorption fine structure (XAFS) at cryogenic temperatures; high-pressure diamond anvil cell (DAC) experiments down to 10 K; ion trap physics requiring ultra-stable thermal anchoring; and infrared detector calibration against blackbody references traceable to NIST SRM 2520.
FAQ
What is the typical cooldown time from 300 K to 1.5 K?
Typical cooldown time is 10–12 hours under no-load conditions; thermal mass and heat load directly influence final stabilization time.
Can the system operate continuously for extended periods?
Yes—the Acryo-1.5K is rated for unattended 24/7 operation with scheduled maintenance intervals every 12 months per manufacturer guidelines.
Is remote monitoring and control supported?
Yes, via Ethernet-connected CryoControl Suite with TLS-secured REST API and optional OPC UA gateway for integration into facility-wide SCADA systems.
Are custom sample holders available?
PHYSIKE offers full mechanical and electrical co-design services for application-specific sample carriers, including thermal anchoring optimization, RF shielding, and multi-layer magnetic shielding integration.
Does the system comply with international safety standards?
All electrical subsystems meet IEC 61010-1 Ed.3 for laboratory equipment; CE marking is provided for EU delivery; UL/cUL listing is available upon request for North American deployment.
