The abort gap is there to give the dump kicker time to switch. Any beam which is in the abort gap receives a partial kick and is lost on the collimators somewhere - it can't go down the dump line.

Re: Antimatter captured for a fifth of a second?

I read the article and it does raise an interesting issue of why so much matter and so little antimatter in our local environment.

Re: Current Events Discussion

The electron cloud is a lot of electrons which are released from the walls of the beam pipe by the electromagnetic field of the passing bunch. They can then disrupt any following bunches. It was predicted that this effect would be seen in the LHC due to the high energy of the bunches. It's hard to o...

So greetings fellow particle-geeks!
