36 bunches of protons and 36 bunches of
antiprotons circulating around the Tevatron
From Accelerator update: Friday, April 27 Recycler commissioned their beamline while the Main Injector and Pbar stacked all night. Pbar started setting up for shots to the TeV at the end of the midnight shift. The shots today will set up for a 36 by 36 store: 36 bunches of protons and 36 bunches of antiprotons circulating around the Tevatron. (A bunch is a distinct group of particles.) This is the normal mode of operation for the colliding beam experiments. At each of the experimental areas the two beams are squeezed (brought together) so there are proton and antiproton collisions. A good squeeze results in the potential for a higher rate of collisions. This potential for particle interaction is called luminosity. The higher the luminosity, the greater the chance of quark production. (Information about quarks) Weekend and future plans There will be shots every day. The Main Injector and Pbar will stack every night. The TeV will work on efficient transfers of beam and on increasing luminosity. Recycler will continue to commission. LINAC and Booster will supply beam for the other machines. |
