Publikováno v: Azzoni, S, May, A J, Chase, S T, Coppi, G, Kenny, L C, Melhuish, S J, Piccirillo, L, Suzuki, A & Wenninger, J 2020, ' A Closed-Cycle Miniature Dilution Refrigerator for a Fast-Cooldown 100 mK Detector Wafer Test Cryostat ', Journal of Low Temperature Physics . https://doi.org/10.1007/s10909-020-02374-w

The forthcoming generation of cosmic microwave background polarization observatories is developing large format detector arrays which will operate at 100 mK. Given the volume of detector wafers that will be required, fast-cooldown 100 mK test cryosta

Closed cycle cooling of infrared detectors to 250 mK

Autor: Peter Mason, S. T. Chase, Brian Keating, G. Sirbi, B. J. Philhour, Andrew E. Lange, W. C. Jones, R. S. Bhatia

Publikováno v: Cryogenics. 42:113-122

We have designed and built a cryogenic system which uses no expendable liquid cryogens and consists of a three-stage cryocooler together with a three-stage sorption cooler to achieve a base temperature of 239 mK. We achieve a temperature of 250 mK at

Publikováno v: Cryogenics. 40:685-691

We review some of the applications of submillimetre instruments for astronomy and Earth atmospheric sciences where helium sorption refrigerators have been used. We describe a three-stage helium refrigerator which uses a 4He–3He double-stage refrige

Submillimetre observations of galaxies – I. First results

Autor: P. Andreani, D. L. Clements, S. T. Chase

Publikováno v: Monthly Notices of the Royal Astronomical Society. 261:299-305

We present the first results from a programme of millimetre and submillimetre observations of galaxies using the UKT14 photometer at the JCMT. Three of the five objects discussed here are detected at 450 μm, and most at 800 μm as well. We perform f

Thermal architecture of the Clover cryostats

Autor: Peter Charles Hargrave, C. North, Peter A. R. Ade, S. T. Chase, William F. Grainger, Brian John Kiernan

Publikováno v: SPIE Proceedings.

We discuss the Clover cryostats, which are dry cryostats containing three stages of cooling; a pulse tube cooler, a sorption fridge and a continuous miniature dilution refrigerator. We describe the thermal architecture of the system and present therm

Closed-Cycle Cooling of Infrared Detectors to 0.25 K for the Polatron

Publikováno v: Cryocoolers 11 ISBN: 9780306465673

We have integrated a 4 K mechanical cryocooler with a three stage 4 He/ 3 He/ 3 He sorption refrigerator to achieve cooling down to 0.25 K. The cryocooler consists of two Gifford-MacMahon stages which cool 4He to below its inversion temperature for u

Observational Cosmology in the Near Infra-Red

Autor: N. Mandolesi, S. T. Chase

Publikováno v: Dusty Objects in the Universe ISBN: 9789401067829

Although we have a fairly good understanding of the structure of the Universe at recent epochs, its history and evolution remain obscure. Clearly we still lack key pieces of the cosmic puzzle. The study of background radiations should be an effective

A search for the Sunyaev-Zeldovich effect at millimetre wavelengths

Autor: Robert D. Joseph, Peter A. R. Ade, S. T. Chase, N. A. Robertson

Publikováno v: Monthly Notices of the Royal Astronomical Society. 225:171-185

The Sunyaev–Zeldovich effect is potentially a powerful tool for observational cosmology. We report the results of the first attempt to detect this small effect at a wavelength of 1.15 mm. At this wavelength the effect has a sign opposite to that at
