@Kalvaer & Claire

Thanks guys, that makes it even more interesting!

2 operational beams!

Day Short summary Link to report from 8:30 meeting
Sunday 6th December

00:00-02:30: Four bunch setup.
a) 1.5e10 p in beam1 in 4 bunches. Fully protected machine. 25h beam lifetime. Correctly dumped.
b) At 01:32: Two beams with each 4 bunches stored. B1: 1.4e10. B2: 1.5e10.
c) Dump tests show normal loss patterns both for bunched and unbunched beams.
02:30-xx:xx: Injecting for stable beams.

Finally successful around 6:30 after resolving a lifetime problem with beam 2. 4 on 4 circulating and colliding with reasonable lifetime for both beams.
9:00 summary pptx for December 5

Eish.. that she is ALOT of power....


Awesome to see the LHC is ramping up nicely...

And then some more

transverse raw energies of 23 GeV
and 16 GeV, and pseudo-rapidities

Quote from the news page:

On Tuesday evening, December 8th, 2009, the LHC achieved for the first time 2.36 TeV collisions and ATLAS recorded their first events at this record energy.

Still no black holes?

FFS, this is turning out to be a let down

 

[Kalvaer]

LOL, We can still hope.

Anyway, I'm typing this here because I'm to lazy to make a new thread. Merry Christmas to you all and a happy new year. I'm about to leave work, head home, finish packing and then I am flying out to Geneva. I should hopefully be at CERN tomorrow afternoon

 

[DJ...]

Lucky bastard - safe travels and keep us posted (lol, see what I did there?)

 

[Kalvaer]

Here safe, Just had lunch at R1 with Claire at CERN.

There are a few Nobel Prize Laureate's sitting around here and I feel so out of place among all these really really smart people

I'm pretty tired though so going to try get some sleep. I'll upload some photo's later.

 

[MadMailMan]

I'll upload some photo's later.

That's if the black holes don't get you first. WHAHAHAHAHAHA. :twisted:

 

[bekdik]

The LHC is shut down 'till Jan/Feb next year.

 

[Kalvaer]

Yeah, it pretty much shut down on wednesday, Cern all closed up on yesterday.

 

[BigAl-sa]

Yeah, it pretty much shut down on wednesday, Cern all closed up on yesterday.

So Claire still hasn't gotten the results she needs?

 

[Dusk]

I'll upload some photo's later.

Can you take a picture of a black hole ???

 

[Kalvaer]

So Claire still hasn't gotten the results she needs?

It will be a while still for her to do that anyway even if they were running.

I must still get some photo's up. I Didn't take nearly as many as I wanted as I ran my battery down on the camera and forgot to charge it each morning on our way into CERN. Claire has a few though that I will steal. Would of been nice though to post some up of the "microcasm" <sp?> tunnels that I went into

 

[smokey]

Can you take a picture of a black hole ???

Only with a camera that will be invented a week after the black hole is created.
