The NA48 cryogenic system has to provide stable thermal conditions (120 K) in a 9000 liter liquid krypton calorimeter, and has to ensure safe and loss free storage of the liquid during idle periods. Direct cooling of the krypton by nitrogen is used in emergency cases, while an intermediate cooler, containing saturated liquid argon at around 10 bar (117 K) is used under normal operation conditions when high thermal stability is needed.

Cryogenics for the CERN Solar Axion Telescope (CAST) using a LHC Dipole Prototype Magnet Barth, K ; Passardi, Giorgio ; Pezzetti, M ; Pirotte, O ; Riege, H ; Vullierme, B ; Walckiers, L ; Zioutas, Konstantin
The axion, an as yet hypothetical particle predicted from the solution of the strong CP problem, constitutes a prime candidate for the galactic dark matter and also arises in supersymmetry and superstring theories. If existing, axions should be copiously produced in stellar interiors and there are theoretical expectations for a low-energy axion emission spectrum peaked around a mean energy of ~ 4.4 keV.

Application of Object-Based Industrial Controls for Cryogenics Casas-Cubillos, J ; Gayet, P ; Gomes, P ; Pezzetti, M ; Sicard, Claude Henri ; Varas, F J
The first application of the CERN Unified Industrial Control system (UNICOS) has been developed for the 1.8 K refrigerator at point 1.8 in mid-2001. This paper presents the engineering methods used for application development, in order to reach the objectives of maintainability and reusability, in the context of a development done by an external consortium of engineering firms.

A Microcryostat for Refrigeration at 1.8 K Bouyaya, A ; Policella, C ; Rieubland, Jean Michel ; Vandoni, Giovanna
A microcryostat has been developed in the Central Cryogenic Laboratory at CERN with the purpose of cooling a prototype beam loss monitor for the LHC, based on bolometry at 1.8 K. Its characteristics a re the very compact volume (some cm3 LHe) ensuring short cooldown-warmup times, and its low heat losses (~ 8 mW). [...] LHC-Project-Report-231; CERN-LHC-Project-Report-231.-
