Just checked in, looks like 3+ hours of both beams at 3.5TeV and holding! Looking good for a big event! (but no detectors are switched on yet)

So if I can put a spin on this (hopefully correct), the graphite is not a hard wall to the protons but more like a net that expands as the protons shoot into it. The resulting kinetic energy would be much lower then a true non moving wall and way less then proton-proton head on as they are the same ...

Well still a longevity record in my book, shows the magnets are ready for 3.5!

Tx for the update

Just checking back in, looks like one beam has been at 3.5TeV for over 2 hours! That's some pretty good stamina. They say the op page is frozen so I guess the 12+ hours of 3.5TeV beam time it shows is not correct? Anyone have a current, correct report on how long it has actually been going? Can't wa...

Beams Injected, another 3.5TeV Ramp starting NOW!!

Beams up - Ramp is Coming!!!!!!!!!!!

From P1:
Both beams injected ... and locking better. we now correct and then we should ramp

Looking like all their ducks are in a row for a 3.5Tev beam tonight! Fingers crossed all goes well, their on count down now!

Anyone else noticed this very large spike in the history today? (op page) By far it's the highest they have wound out the machine to date. I wonder if it was intended as it is so short?

Got the answer sooner then expected, from p1

"An AUG triggered in point 7 due to bad contact. Recovering LHC from the power cut. No beam before 9h00"

Anyone know what an "AUG" is? (it's not on the posted list yet)


So the news is good!!!!

Well the Cyro status board is all green again so it looks like it was not a major event (thank goodness!) It's late here in the states so I am signing off until morning, should know by then the final resolve.

I only hope this translates to just electrical damage and not physical magnet damage. Everyone keep your fingers crossed.

Possible fire! More from op log; 02:49 Fire brigade . electrician piquet . radio protection piquet . G.H in point 7 for access. Switchin OFF RF 02:50 We have closed the vacuum valves of the machine .except the ones between the MKIs.. we have switched OFF all the magnets. the RF. 03:03 BIC communicat...

Well just had a big hickup Lost all comm in S67 and S78, now saying a power cut in point 7 with alarms at level 3.

Hope it's not as bad as it sounds.

Wow, just started 2 beams of 1E10!! Hopefully fireworks will follow soon
