Beam and detectors - A Beamline for Schools

... Trigger and readout Signals from some of the detectors are used to build the trigger. The trigger logic identifies interesting interactions (“events”) and instructs the computer to initiate the readout of the data from all the detectors. The trigger is a fundamental and complex component of LHC expe ...

... We present a new approach to measuring the neutrino-spin correlation parameter B in neutron decay. The approach combines the technology of large-area ion-implanted silicon detectors being developed for the abBA experiment, with an ultracold neutron source to provide more precise neutron polarimetry. ...

... The remarkable power ascribed to Nature by modern atomists is nothing other than that power attributed to the atom by ancient atomists. The materialist philosophy is welldescribed by a modern student of the ancient atomists who wrote: “Thus, the inherent power of the atom to move by its own weight p ...

The process is not exactly completely reversible to the annihilation process as described above, claiming not 2 single photons, instead one single photon with the double of energy. Hence, if we make use of a p ...

Antimatter

In particle physics, antimatter is material composed of antiparticles, which have the same mass as particles of ordinary matter but opposite charges, as well as other particle properties such as lepton and baryon numbers and quantum spin. Collisions between particles and antiparticles lead to the annihilation of both, giving rise to variable proportions of intense photons (gamma rays), neutrinos, and less massive particle–antiparticle pairs. The total consequence of annihilation is a release of energy available for work, proportional to the total matter and antimatter mass, in accord with the mass–energy equivalence equation, E = mc2.Antiparticles bind with each other to form antimatter, just as ordinary particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton (the antiparticle of the proton) can form an antihydrogen atom. Physical principles indicate that complex antimatter atomic nuclei are possible, as well as anti-atoms corresponding to the known chemical elements. Studies of cosmic rays have identified both positrons and antiprotons, presumably produced by collisions between particles of ordinary matter. Satellite-based searches of cosmic rays for antideuteron and antihelium particles have yielded nothing. There is considerable speculation as to why the observable universe is composed almost entirely of ordinary matter, as opposed to a more even mixture of matter and antimatter. This asymmetry of matter and antimatter in the visible universe is one of the great unsolved problems in physics. The process by which this inequality between particles and antiparticles developed is called baryogenesis.Antimatter in the form of anti-atoms is one of the most difficult materials to produce. Antimatter in the form of individual anti-particles, however, is commonly produced by particle accelerators and in some types of radioactive decay. The nuclei of antihelium (both helium-3 and helium-4) have been artificially produced with difficulty. These are the most complex anti-nuclei so far observed.
