Suoria mäjjäytyskuvia LHC:stä!


Kah, bongasin netin syövereistä pari mielenkiintoista linkkiä. Tässä pitäisi olla "suoraa kuvaa" LHC:n kahdesta ilmaisimesta.

Näyttäisi tosin, että tällä hetkellä ei beamit ringissä pyöri, jos tähän sivuun on uskominen:

Vieläkun noista kuvista jotain tajuaisi.

Tässä otteita pressitiedotteesta:

For the rest of the year the LHC is moving to a different phase of operation, in which lead ions will be accelerated and brought into collision in the machine for the first time.
A major target for 2010 was to reach a luminosity – a measure of the collision rate – of 1032 per square centimetre per second. This was achieved on 13 October, with two weeks to spare. Before proton running came to an end, the machine had reached twice this figure, allowing experiments to double the amount of data collected in the space of only a few days.
The main goal for 2011 is for the experiments to collect enough data – an amount known by the physicists as one inverse femtobarn - to make significant advances across a broad frontier of physics.
The LHC experiments have already entered new territory with their first measurements at a total energy of 7 TeV. The results so far have included the validation of aspects of the Standard Model of particles and forces at these new high energies; the first observations of the top quark in proton-proton collisions; limits set on the production of certain new particles, for example “excited” quarks; and hints of effects in proton-proton collisions that may be linked to previous observations in the collisions of heavy ions.
The change to running with lead ions – lead atoms stripped of electrons - opens up an entirely new avenue of exploration for the LHC programme, probing matter as it would have been in the first instants of the Universe’s existence. One of the main objectives for lead-ion running is to produce tiny quantities of such matter, which is known as quark-gluon plasma, and to study its evolution into the kind of matter that makes up the Universe today. This exploration will shed further light on the properties of the strong interaction, which binds the particles called quarks, into bigger objects, such as protons and neutrons.
The WLCG faces a new challenge with lead-ion collisions, as the flow of data will be significantly greater than for proton-proton collisions. Recent tests have demonstrated the readiness of the date storage system at CERN to accept data at more than three times the rate achieved for proton-proton collisions, and more than double the rate originally anticipated for heavy ions.
The LHC will run with lead ions until 6 December, before a technical stop for maintenance. Operation of the collider will start again with protons in February and physics runs will continue through 2011.
