LHC@home

Asequesed and for your information Miriam has described her
recent studies as follows:
A principal component of the planned upgrade to a high luminosity LHC (HI-LHC) is the replacement of the high field quadropole magnets - the so called "inner triplet".
The long term beam stability can be significantly reduced by magnetic field errors, miasalignment of the magnets and by irregularities in the power supply (ripple). The recent batch of fifteen or so studies, involving over one and a half million cases or Work Units each of one million turns (for a stable beam), are aimed at determining the maximum allowable tolerances for the power supply ripple assuming the known field and alignment errors.

That reminds me of 7 years ago here http://www.fnal.gov/pub/today/lhc_magnet_archive.html

As long as the birds and the flying sandwich didn't cause problems again

But no problem with tasks for me lately.

Almost 10 years and I finally made it to the 1 million credit st(and this too http://www.fnal.gov/pub/presspass/press_releases/2013/LHC-New-Magnets-20130711.html)

Thx for the info eric :)

When do you think conclusion will be known?

Pretty impressive Fancy Dan computation on all that. The power supply is a bit more powerful than your atypical PC gaming rig PSU. The caps in that thing prolly big as a truck packing a few kF, and the inductor coils prolly bigger'n your house.

The energies being harnessed by the cyclotron are respectable; the few hundred particles being whirled about have energies congruent to the momentum of aircraft carrier at flank speed. All around the cyclotron whirl-tube are emergency off-ramps - akin to those found on mountain roads - that are packed with multi semi-trailer trucks worth of graphite.

When the particles escape the grasp of the magnetron beamer thingy, and they shoot up one of the escape ramps, the whole pile of graphite gets hot as steam.

So we all be crunchin' for good affect.
