Progress in Cryocoolers

Dear Colleagues,

Since the first liquefaction of the last “permanent gas” ⁴He in 1908 by Kamerlingh Onnes, the fascination with improving the efficiency of cryocooler has endured. Currently, a variety of cryocoolers have been put into application and play key roles, including the storage of biomedicine (~200 K), liquefied natural gas (~110 K), infrared detector cooling around 77 K, high-temperature superconducting magnet cooling (~40 K), liquid hydrogen (~20 K), liquid helium (~4 K), and low-temperature superconducting magnet cooling (~1.8 K). These cooling requirements can be satisfied by the following typical cryocoolers: Joule–Thomson (JT) cryocooler, Gifford–McMahon (GM) cryocooler, Vuilleumier (VM) cryocooler, pulse tube cryocooler (GM type, VM type, Stirling type), thermoacoustic cryocooler, and other hybrid cryocoolers. On the other hand, the development of cryogenic magnetic regenerator materials, cryogenic heat transfer, and computational fluid dynamics methods have also greatly promoted the development of the cryocooler. Currently, space exploration, quantum computing, and precision physical measurement have put forward new demands on cryocoolers. Cryocoolers are being developed towards compactness, large cooling capacity, and low vibration. This Special Issue is dedicated to showcasing and sharing the latest progress across the entire cryocooler spectrum. We invite authors to submit original research articles, review papers, and case studies that fall within the following topics:

• Joule–Thomson (JT) cryocooler;
• Gifford–McMahon (GM) cryocooler;
• Vuilleumier (VM) cryocooler;
• Pulse tube cryocooler (GM type, VM type, Stirling type);
• Thermoacoustic cryocooler;
• Hybrid cryocooler;
• Regenerator;
• Heat transfer;
• Computational fluid dynamics;
• Various cryocooler applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cryo is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
