Gamma Conversion into a Muon - Anti-muon Pair ; Normalized differential cross section for pair production as a function of x, the energy fraction of the photon energy carried by one of the leptons in the pair. The function is shown for three different elements, hydrogen, beryllium and lead, and for a wide range of photon energies.

A new generation of particle accelerators that use laser acceleration can sit on the benchtop. These instruments are being actively developed for widespread applications.

A micron-scale aluminum LC circuit, composed of a straight-wire inductor (green) and comb-shaped capacitors, is fabricated on the surface of a bismuth-doped silicon sample. When the circuit is excited at its resonant frequency of 7.3 GHz, the oscillating magnetic field (brown) around the inductor interacts with the nearby Bi–electron spin pairs. The circuit’s presence alters the spectrum of allowed photon states the spins can couple to and thus the spins’ rate of spontaneous emission.

Figure 1. Principles and imaging modalities of single-photon emission, two-photon emission, and up-conversion luminescence (UCL). Photographs illustrate fluorescence in a cuvette of rhodamine B resulting from focused laser beams using single-photon excitation with continuous wave (CW) at 488 nm (a), two-photon excitation with femtosecond pulses (FS) at 880 nm (b), and UCL of UCNPs under CW excitation at 980 nm (c). In particular, the excitation path in panel c goes through the cuvette from…

A design plan for a full-scale muon-antimuon collider at Fermilab, the source of the world's second-most powerful particle accelerator.

There's more than one type of radiation. In fact, there are 4 main types to discuss: electromagnetic, alpha particle, beta particle, and neutron.
