    Design, Construction, Installation and First Commissioning Results of the LHC Cryogenic System

    Get PDF
    The cryogenic system of the Large Hadron Collider (LHC) will be, upon its completion in 2006, the largest in the world in terms of refrigeration capacity with an equivalent to 144 kW at 4.5 K, about 400'000 litres of superfluid helium with 25 km of superconducting magnets below 2 K leading to a cryogen inventory of 100 tons of helium. The challenges involved in the design, construction and installation, as well as the first commissioning results will be addressed in this talk. Particular mention will be made of the problems encountered and how they were or are being solved. Perspectives for LHC will be presented. General considerations for future large cryogenic systems will be briefly proposed

    Cryogenics, a service ? Surely you're joking !

    Upgrade of Four Cryogenic Helium Refrigerators used in the LEP Collider for LHC Refrigeration

    Get PDF
    After the final run of the Large Electron Positron Collider, the four refrigerators used for LEP were free to be used for the Large Hadron Collider project. In order to serve the LHC requirements, these four Ex-LEP refrigerators needed to be modified and upgraded. In this paper we present the requirements for these refrigerators operating for the LHC machine compared to those for LEP, the necessary modifications of the existing machinery and the additional equipment needed. We will also compare the cost of the upgrades with the cost of the new LHC refrigerators

    Emotions' Impact on Tourists' Satisfaction with Ski Resorts. The Mediating Role of Perceived Value

    Get PDF
    International audienceEmotions have been shown to play an important role in consumers' evaluation of their consumption experiences, including extended multiple-encounter touristic ones. The present research investigates the emotions used in the evaluation of customers' experience at a ski resort and how these emotions drive customers' satisfaction. Two quantitative studies are conducted in the French Alps and the data analysed with descriptive statistics and structural equation modelling. The findings uncover the importance of three emotions - joy, excitement and peacefulness - and a strong mediating role of overall perceived value between consumption emotions and satisfaction. Emotions related to "surprise" play no significant role in the evaluation of the ski resort experience. The present findings suggest that managers should focus on staging customers' stay at the resort to stimulate an emotional experience and position their packages based on the promise of such emotional experiences
