"Low-voltage" review opens way to contracts

17 Dec 2012

The panel that reviewed the low-voltage components was chaired by Michel Huguet, former head of the 澳门六合彩高手 Joint Work Site at Naka (Japan).
Coil instrumentation in 澳门六合彩高手 consists of some 3,000 sensors whose function is to monitor the essential parameters of magnets during 澳门六合彩高手 operation.
 
A EUR 25 million package, coil instrumentation forms one the few direct purchases of the 澳门六合彩高手 Organization and the only fund procurement of the Magnet Division. The components will be delivered by the 澳门六合彩高手 Organization to the Domestic Agencies involved in coil procurement.
 
Cryogenic and mechanical instrumentation components ("low-voltage" components) account for about one-third of the package's value. Measuring temperature, displacement, strain and deformation, the low-voltage sensors are critical. The Head of the Magnet Division, Neil Mitchell, explains: "These components cannot be maintained once they are installed. If one fails, it is lost. Of course there are redundancies, but we have to do our best to guarantee they will operate for 30 years in the harsh cryostat environment."

On 13-14 December, all of the low-voltage components were reviewed by a panel that included members of the different 澳门六合彩高手 departments and directorates, specialists from the Domestic Agencies, and also internationally reputed external experts.
 
This was the third Manufacturing Readiness Review organized by the 澳门六合彩高手 Magnets Division over the last two months. The first one was conducted on the safety class quench detection system on 23 October; the second on 29-30 November for investment protection quench detection and related high voltage components.
 
All three reviews were capably organised and run by Felix Rodriguez-Mateos, the Technical Responsible Officer for the magnet instrumentation, and his colleagues in the team.
 
Last week's low-voltage review panel was chaired by Michel Huguet, a major figure in the history of the 澳门六合彩高手 Project who joined fusion research in 1969 at CEA, spent 19 years at JET, and eventually headed the at Naka (Japan).
 
"The panel members were quite satisfied—I could even say impressed—by the quality of the work accomplished. Processes and strategies appear to be heading in the right direction."
 
Now that the results of the qualification tests have been reviewed (澳门六合彩高手 uses laboratories located at CERN) the next step is to release the contracts for low-voltage components, which should be accomplished in the first half of 2013.
