Current Events Discussion
Re: Current Events Discussion
I liked the quote from one of the boffins when he said 'we may even discover some unknown unknowns'
Re: Current Events Discussion
New Record! Beam for over 8 hours and at 3.5TeV too!
Re: Current Events Discussion
The beams are still going, and with good lifetimes, too!
And LHCb just had a bizarre event: http://lblogbook.cern.ch/Shift/100401_0 ... 4210_0.jpg

Re: Current Events Discussion
Whoops, beams gone. Hope there were some interesting collisions.

Re: Current Events Discussion
I read around 10 hours, looks like a new record to me
Re: Current Events Discussion
Seems like Cryo is rather borked again today. Page 1 says they intend to sort it out by 2000.
So whilst we wait, seems we'll be attempting to break Igor...

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

Re: Current Events Discussion
No wonder, looks like parts of the machine had time to warm up a lot. Still too many red squares on cryo page.

Today's morning dump was scary.

how so mate?
Yesterdays Atlas fireworks were mad tho, nothing.... nothing.... BOOOOOOOOOOOOOOOOOOM tracks everywhere so much you couldn't make any sense lol
Re: Current Events Discussion
I was looking at page1 shortly after the beam was dumped and they put on beam tracking screens showing one beam mark in the center and one way off (by centimeters, not millimeters). Should this happen with full intensity beam I'd be afraid about beam pipes getting perforated by it.

COLL-MOT-b2?
Now it is already the second time I see a dump during setting up for phzsics with the reason "COLL-MOT-..." while moving in the collimators.
What is that?
What is that?

Re: Current Events Discussion
Not sure if this will fully answer your question but from the "CERN BE - OP eLogbook"
Unprogrammed dump. When completing collimator sequence. TCT and TCLs were out of tollerance.
I have been (very slowly) putting together a spread-sheet of all the acronyms used on the various screens; I have the following defs ...
TCT - Target Collimator Tertiary: Tertiary Collimator
TCL - Target Collimator Long

Re: Current Events Discussion
A nice little animation of "collapsing separation bumps" that is part of the beam physics process:
