Hi all,
have a look at LHC-OpenDay there you will find a lot of informations.

There is a very large spread/article, on LHC, in this months “National Geographic” magazine. Some really good pictures.

I don’t know much about the Boinc LHC.

You may know some magnets went bang recently at the project! Something about a metal hairpin flying off a female scientists head as they powered up for a test…I think.

I personally suspect that the line "restraining defendants from operating the LHC or further preparing the LHC for operation for four months" is the reason behind the extended "Down for Maintenance" status of the @home project.


I still don't think this is the reason.

The LHC@home website is still down but the BOINC project is still sending out work.

The main LHC website and the CERN public LHC site are still up.

I think it is just a problem with the LHC@home BOINC project website.

They have also not updated any stats on sites like BOINCstats since 31 March.

I even doubt that this is the case. Like you, I've been receiving new work (not resends), crunching it, sending it back and getting credit for it (so the validators are working).

I would strongly suspect that the statistics are being generated as well: the problem would be that the statistics sites can't get hold of them. If you try to visit http://lhcathome.cern.ch/stats, you hit the same redirect to the maintenance message as you do on the front page.

I guess lhcathome is a mini blackhole, evaporating only through Hawking radiation.

The court case is being taken in Hawaii. What jurisdiction does a Hawaiian court have over Cern that stradles the Swiss - French border? Cern is probably just ignoring the Hawaiian court.

John,

There are American scientists, and some of our money and our participation ... all of which ARE under the jurisdiction of the federal court in Hawaii ... though likely to lose on appeal, they can just make a snit and cause problems ...

As a for instance, prevent, or require a block on any US participant doing any LHC tasks ...

Tie up US funding from going over to finish up the system.

Etc.

Doomsday machine ready – head for Hawaii!

DALE McFEATTERS
SCRIPPS HOWARD NEWS SERVICE

April 11, 2008

If you're going to have to wait out the end of the world, Hawaii is a pretty good place to do it, which could be why two scientific skeptics chose to file suit there to stop a physics experiment in Switzerland that might – might, mind you – go awry and destroy the Earth.

This summer physicists will fire up the Large Hadron Collider to send particles hurtling around a circular tunnel of just over 16 miles at speeds close to the speed of light until they smash into each other, and when they do scientists hope to get a look at the elusive and still theoretical Higgs boson, which we laymen know by the sexier name the “God particle.”

The debris from that collision could – could, mind you – give us a mini-glimpse into how the universe was created and offer a mathematically consistent explanation of everything scientists don't know about particles, the Unified Theory of Everything. Or maybe not. Scientists say they could just as easily be stuck with a whole bunch of new unanswered questions.

The two skeptics filing suit to stop or delay the experiment say a whole bunch of other things might happen, all of them bad. That possibility has led some to label the collider the Doomsday Machine, a much sexier name but one of dubious public relations benefit.

For example, the LHC could create a swarm of mini-black holes that could coalesce into a larger black hole and swallow Switzerland, maybe all of Europe, even the entire Earth. Not good.

Or, another theory put forward by Walter Wagner and Luis Sancho, the filers of the suit, is that a chunk of matter called a strangelet would, if unleashed, turn everything it touches into another strangelet until the entire Earth is a modest lump of something that looks like a cinder. Our time may be coming but I think I speak for all of us when I say we don't want to go into oblivion because of a strangelet.

A third possibility is that the collision creates massive particles called monopoles that would wreak whatever havoc massive monopoles customarily wreak. The Earth already has two poles and adding a third does not sound like a terribly good idea.

The suit calls for the U.S. government to do a full-scale review of the collider project to ensure that it is in compliance with all applicable environmental regulation. That really is carrying regulation to excess when a Doomsday Machine has to be environmentally friendly.

The LHC, as it happens, is partially in France, and if it does start to melt down it would be worth being there to watch the French technicians trying to push the black holes and strangelets to the Swiss side of the border.

While the scientists will be smashing particles this summer – some oldsters show their age by calling it an atom smasher – it won't reach its full capacity of 14 trillion volts until next year. So there's still time to get on out to Hawaii.

They apparently still have some issues, their Server Status Page indicates that aside from the web, everything is DOA. The server history makes it look like things went down not too long after it all came back after the extended down time

I think the project project is down due to the law suite filed against them

Hi,
Sorry about the sudden and lengthy suspension of the website. As you may have noticed work units were still coming and going so operation of the project was still ongoing. The reason for the suspension was CERN asked (read: told) us to remove some 'inappropriate content' which was spam within profiles of users. This was a bigger issue than originally thought and we've been searchin through profiles and purging the database when we've had time to do so. We are really sorry but this had popped up in the midst of a whole mess of other things (I've actually been away for most of it) and wasn't done very quickly.
Again thank you all for your patience and I got all your emails and we know it was CERN's open day etc etc.
Later days,
Neasan.

The other things may be what I eluded to in my earlier post, there was a problem:


In late March, a scant few months before the much anticipated Large Hadron Collider (LHC) was slated to go online, a small but crucial part of the machine broke with a bang.

The accident happened as a team was testing a set of magnets that will steer protons—tiny positively charged particles found in every atom's nucleus—around the accelerator to nearly the speed of light.

When the pressure inside got high, it snapped supports holding the magnets, and gas burst out of the tube, stirring up a cloud of dust. No one was hurt, ,BUT THE DRAMATIC FAILURE REVEALED A DESIGN FLAW IN THE MASSIVE MACHINE.

We now intend to make the tests, which will allow the technicians to drive the machine, in late April or early May [next year 2009] and then hopefully go into full startup as planned by next summer. Scientists are thankful that they caught the problem before the machine actually powered up.

A spokesperson was heard to say that overclocked/unstable computers returning bad information at LHC@home may have contributed to the faulty design flaw.

Hold on: That last sentence wasn't really in the article...was it?
