Flatiron™ Dilution Refrigerator
  • Flatiron™ Dilution Refrigerator

The Flatiron™ Dilution Refrigerator is HPD’s compact, benchtop millikelvin platform designed to simplify sub‑kelvin optical and electrical measurements for quantum device development, advanced materials research, and quantum hardware validation. Unlike traditional dilution refrigerators that rely on large, vertical “chandelier‑style” architectures, Flatiron features a novel horizontal design that improves accessibility, workflow efficiency, and lab integration.

Designed for modern research and engineering environments, Flatiron enables millikelvin experiments in a lab‑ready system that fits naturally alongside optical tables and standard laboratory equipment. Its ergonomic benchtop architecture provides direct top-plate access to the sample stage, allowing researchers to change samples and reconfigure experiments without removing multiple vacuum cans or radiation shields. This streamlined access reduces experimental overhead, supports frequent thermal cycling, and accelerates time‑to‑data compared to full-scale dilution refrigerator systems.

Building on HPD’s expertise in cryogenic systems and FormFactor’s leadership in test and measurement, Flatiron provides reliable millikelvin performance in a compact, labfriendly platform. A large experimental volume, integrated cryogenic optical access, and flexible electrical and RF configuration options make Flatiron well suited for optical, electrical, and chip‑scale quantum device research, characterization, and validation. Designed for high uptime and ease of use, Flatiron provides a practical, high‑throughput platform for both research institutions and industry teams advancing quantum technologies.
