They cruise in vacuum so there's not much to hear.

No worries, I was only joking.

*grmbl* Of course LHC has all sorts of problems and hiccups when I am around (yesterday during the day) and when I'm off to sleep it suddenly started working A-OK... Ok, but seriously now. I've seen from various status reports and logs that there has been some good stuff last night (first time with ...

Congrats, Chris! Way to go!

Yey!! (for those Twitter shouts)!

Update on the schedule as on http://lhc-commissioning.web.cern.ch/lhc-commissioning/news/LHC-news.htm: Note that at the time of posting this here, it says above the schedule: "Following schedule to be re-done when length of 18 kV drop stop is known." SAT 8:00 Re-establish machine reference - orbit, ...

So, do you agree with my assertion about crude errors in documents about our safety from Collider? Read and say. I (and I suspect most if not all of us here on this forum) am unable to judge this as I lack the required background. However, since you make extraordinary claims you will need extraordi...

Wow, you shared it with CERN... Dang, you should have told me. I'd made sure that my hair was brushed and I'd have put on a clean shirt... (just kidding!!) :lol: But seriously. Here's a small addendum to straighten out one obscure sentence. When I re-read my original post I found it unnecessarily my...

hehehe

Ah, ok thx!

If there is noise, there has to be something that vibrates. So what vibrates in there that could make noise? Indeed, cooling, power supply, cryo, ventilation. Not the magnets though. (But I agree that it's a nice mental picture: a whine that gets ever louder and higher when LHC starts accelerating p...

I have seen the power converter of the PS (well, the old one, and the new one we are currently working on it). If already 50 years ago they were able to do such machine that resilient to power cut, I believe for the LHC it is really not something to bother about. Protection, redundancy and backup c...

Is there public info about safety measures at LHC in case of power loss? Come to think of it, is something known about the LHC's power consumption? Of the accelerator? Of the experiments? I mean, power loss is obviously an eventuality you need to be prepared for. A power loss just seconds before hig...

With an experiment named ALICE, and all this talk of "Down the Rabbit Hole", I just *had* to have an Alice In Wonderland forum name. It's my favourite book. Sorry if you find it cheesy... :lol: First I got to get something off my chest... I had NO IDEA that so much LHC info is publicly accessible. A...
