Supercomputers aid Gamma Ray Research

Authors: George Rajna

UC San Diego mechanical and aerospace engineering graduate student Tao Wang recently demonstrated how an extremely strong magnetic field, similar to that on the surface of a neutron star, can be not only generated but also detected using an X-ray laser inside a solid material. [33] Combining principles from computational fluid dynamics and acoustics, researchers at the TU Berlin have developed an analytical model that could simplify the process of designing Helmholtz resonators, a type of noise cancelling structure used in airplanes, ships, and ventilation systems. [32] During this run, from 2015 to 2018, LHC experiments produced unprecedented volumes of data with the machine's performance exceeding all expectations. [31] The proposal envisages a new 100km circumference tunnel that would be bored through the Earth, encircling the city of Geneva and the surrounding countryside. [30] On Wednesday, 25 July, for the very first time, operators injected not just atomic nuclei but lead "atoms" containing a single electron into the LHC. [29] The case for an ambitious new particle accelerator to be built in the United States has just gotten a major boost.[27] Physics textbooks might have to be updated now that an international research team has found evidence of an unexpected transition in the structure of atomic nuclei. [26] The group led by Fabrizio Carbone at EPFL and international colleagues have used ultrafast transmission electron microscopy to take attosecond energy-momentum resolved snapshots (1 attosecond = 10-18 or quintillionths of a second) of a free-electron wave function.
