Quote: A small percentage of WU's terminate very rapidly in the case where the particles are lost due to beam instability - which is very interesting for us if not for the donor's credit - sorry!

The credits don't worry me, I was unsure of whether those low credit WU's were of value to your project - thanks for the report. Out of curiosity, why do the beam instabilities interest you?

Out of curiosity, why do the beam instabilities interest you?

If the LHC is run with a setup leading to an instable beam the beam can crash into the the wall of the vacuum ring. The LHC beam has so much energy that this can destroy the wall, damage the detectors and lead to very expensive repairs and iterruption in the experiments.

LHC@home helps the designers find out which combinations of machine paramters are safe to use when the LHC begins operating.

Thankyou for the info. Suspected the instabilities were detrimental to the running process, but had no idea they were also so destuctive.

There will be an enormous amount of energy in the LHC beam.
It has been computed that the proton beam from the LHC could work its way through 30m of solid copper. Likewise a swarm of proton from the LHC will have the energy to melt about 500kg of copper. So doing simulations in advance is a good idea.

It has been suggested that one could use the LHC to create collisions like this, but with special targets, on purpose to study the plasmas created in the collision.

Also, the more stable the beam is under normal situations, the more leeway you have when you want to increase the speed of the objects your accellerating and still keep a stable orbit.

I'm not the LHC Alex. Just a number cruncher like everyone else here.
