> And they're planning to test bunch trains too
So I see. I haven't managed to find out exactly what a bunch train is - though I can make a good guess - can anybody give me a shortish description?
And 48 bunch operations too ... very impressive steady progress.

Re: Current Events Discussion
Hi,
as they are planning to test "bunch train operation (1 train of 4 bunches, each separated by 150 ns)", i think they are just going to put the bunches in buckets separated by 150ns (i.e. moving the bunches closer together).
Please correct me, if I should be wrong!
Best regards

Re: Current Events Discussion
Man I like that chart now Ramp up to 3.5 and back down in 30 minutes!!!
Now they can really step up the short tests.
Great job guys!!!

Re: Current Events Discussion
this pleases me sooooooooooooo much

Re: Current Events Discussion
Expected 12 steps for 48 bunches, but saw 14!

Re: Current Events Discussion
Does anyone know when they're going to use 10A/s ramp rate for regular operations? Since the successful test of last week end I haven't seen anything...

Re: Current Events Discussion
New record inst. Luminosity >6 (ub.s)^-1 using 48 bunch beams.
Bornerdogge I would assume so as anything to speed up recovery times is a good thing.

Re: Current Events Discussion
they are movin fast! allready 48 on 48 stable beams!
Re: Current Events Discussion
This machine is really starting to hum now! Just think we are still in baby steps, man whats to come will be awesome.
Re: Current Events Discussion
A perfect first 48 bunch run ... then we lose cyro in point 6 for 18 hours (no beam before Sat lunch)
