Science LHC working very nicely, thank you

[Belisarius]

This report from the BBC explains that "the collider had done more in a few hours than it did in nine days of operations last year".

Seems like the mysterious glitches caused by future interference from the Higgs Boson - not wanting itself to be discovered - have finished for the moment.

Now they're getting ready to fire that baby up to 1.2 TRILLION eVs - hang on to your hats boys, the black holes are comin' to get ye!

 

[Dig Gil]

Should the Probe comply? .

I didn't read your link and maybe I'm acting stupid, but is there any schedule for the experiments?

 

[Linguofreak]

I found some rather interesting data on the... well... data that the detectors on the thing will be putting out. The primary detector will deal with a petabyte of data a second and will have to decide what is interesting enough to keep and what to throw out so as to be able to keep the data flow manageable. "Manageable" in this case being 100 megabytes per second. My hard drive would be filled up by that within an hour.

 

[Belisarius]

There is a schedule for the experiments:

0900 Switch on the LHC
0905 Go out for coffee
0915 Have another piece of pie
0920 Discuss last night's football
0930 Remember - O MY GOD! - we've left the LHC running at 1 Trillion eV
0931 Run back to the office
0932 Too late, a black hole has already formed and has eaten half of Switzerland
1000 Issue a press release apologising for the swallowing of the whole planet
1005 Issue a press release stating that the team is "close to a breakthrough"
1010 Issue a press release complaining about the quality of coffee in the CERN canteen

Does... not... compute...

Wahooooooooooooooo Black hole's coming to get us.

Save us

During 14 months of repairs dozens of giant superconducting magnets that accelerate particles at the speed of light had to be replaced.

Ok, I know circular motion is accelerated motion, so technically speaking they're correct... but the acceleration along the length of the tunnel is done by a pulsating electric field, no?

 

[garyw]

I think so - the magents are just there to guide the beam to a very precise point

 

[Urwumpe]

Actually, it is a bit more complex:

 

[RisingFury]

You can't get a magnetic force in the direction of the movement. You need an electric field along the length of the pipe and use the magnets for steering the beams.

Of course it's not as simple as that... you have to consider that the beam itself creates a magnetic field, you have to take into account that as you inject protons into the beam over time, they're at different energies, so you need to constantly vary your magnetic and electric fields... you need to take into account that the change of electric field produces a magnetic field and so on and on...

 

[Urwumpe]

Which is why you have special kickers, which inject the new particles in the exact moment. and all particle accelerators use oscillating electric fields for acceleration.

 

[RisingFury]

Well... yea...

The main point was: Electric fiels are used for particle acceleration, magnetic fields are used for guidance.

 

[Urwumpe]

Well... yea...

The main point was: Electric fiels are used for particle acceleration, magnetic fields are used for guidance.

And electric eels for power supply.

Smashing atoms is like trying to learn how cars are put together by crashtesting them..

That is actually not true, but you can learn a lot about how cars are made by crashing one... trust me, I know.

And just wait for the Higgs to figure out we've started again, maybe this time a loofa from Bed, Bath, and Beyond will magically fall into a crack and take it out.

No, it's more like manufacturing WWI era battleships by crashing passenger cars together at relativistic speeds. The only problem is that you can't keep your battleship long enough to actually see it: it falls apart into a collection of small ships, airplanes, cars, tricycles, etc. before it can be detected (some of which fall apart into various things themselves), and you have to figure out that there was a battleship there by examining the debris.

Gosh, that sounds like a lot of fun. I wish I'd stayed awake in Physics classes in school, I could be playing with sub lightspeed battleships now.

Insanity: got your reference to the weird movie with Adam Sandler and Christopher Walken in it. But then the Higgs would be Christopher Walken in that scenario, a prospect too scary for words...
