Magnet’s ramping!

Just a quicky-the CMS magnet ramps have started in the last few days – this is critical for us, since the last time we really turned on this magnet it was on the surface, about 2 years ago (nearly to the day!). Here’s the plot of the current (in Amps) versus time for the last few days – last night they reached 10 kA, about half of what they eventually plan to get to, but one does these sorts of things pedantically and carefully.  Keep in mind your house probably has 100 A service – so 10 kA is 100 Houses!  That’s a lot, but that’s the beauty of superconductivity.

I believe the plan is to go to 3/4 of full field this evening.   Soon all those event display pictures with tracks will be curving!
