The LHC announcer

Post by oxodoes » Mon Aug 09, 2010 10:01 am

Good news everyone! As of today the offical LHC Announcer is publicly available at:

This is the same system that is in use in the CCC and that we have first heard of during the 3.5 TeV media event. It gives us a lot of previously unavailable informations (collimator movement, live beta values, wire scans, bucket numbers ...) in a very convenient way.

Thanks to everyone who has helped making this public

Anyone who doesn't take truth seriously in small matters cannot be trusted with large ones either by Albert Einstein.

Celladore I believe they are groups of corrector magnets that are turned on at various parts of the cycle some before the ramp and others after the ramp.

" The LHC is a complex machine requiring more than 7400 superconducting corrector magnets distributed along a
circumference of 26.7 km. These magnets are powered in 1446 different electrical circuits at currents ranging from
60 A up to 600 A."


So I believe they have various combinations of the above corrector magnets arraigned in groups to simplify what is a complex procedure of producing collisions precisely where required.
