Bluefors today announced the immediate availability of their new Ultra-Compact LD dilution refrigerator system – an all-in-one, compact cryogenic measurement system ideal for lab environments with limited space.
Dilution refrigerators provide essential ultra-low temperature cooling for quantum devices, for example those used in quantum computing. The Ultra-Compact LD integrates all the necessary components of the dilution refrigerator – a Bluefors LD cryostat, Gas Handling System Generation 2 and pulse tube compressor – into one tidy, easy-to-access, compact system that incorporates generous rack space for measurement electronics, and can be placed anywhere in a lab.
The system introduces a number of new and improved features designed to bring an enhanced user experience to customers. Utilizing multiple dampening solutions to deliver low-vibration operation, the system also generates sound levels that are 8-14 dB lower than the standard Bluefors LD, making it an ideal for labs where the measurement system is installed in the same space as users’ workstations. With doors providing easy access to the gas handling system and pulse tube compressor, and an integrated 19” rack with 10U available for additional measurement electronics, the Ultra-Compact LD makes installation, setup and operation simple and efficient.
Bluefors Dilution Refrigerator Measurement Systems are renowned for their unmatched reliability, with over 1400 units in operation worldwide. The Ultra-Compact LD is based on the world’s most widely-used dilution refrigerator, the Bluefors LD – a proven and highly versatile system that can be customized for many different use cases via a vast catalog of performance-optimized measurement infrastructure, a selection of superconducting magnets (with ≤ 3 Tesla z-axis field magnets available), and many other options that enhance the system functionality.
Bluefors’ co-founder, Rob Blaauwgeers, says, “The new Ultra-Compact LD brings world-renowned Bluefors power and flexibility to laboratories with limited space. It also simplifies the implementation of quantum technology in environments like high-performance computing centers. I’m immensely proud of the work our team has put into developing this new, cutting-edge system, and look forward to seeing how the Ultra-Compact LD will be put to use by our customers.”
