More recently, Friedwardt Winterberg proposed that a matter-antimatter GeV gamma ray laser photon rocket is possible by a relativistic proton-antiproton pinch discharge, where the recoil from the laser beam is transmitted by the Mössbauer effect to the spacecraft. [52]
A gamma-ray laser, or graser, is a hypothetical device that would produce coherent gamma rays, just as an ordinary laser produces coherent rays of visible light. [1] Potential applications for gamma-ray lasers include medical imaging, spacecraft propulsion, and cancer treatment.
While at the University of Illinois at Chicago, Solem and colleagues developed an analytic theory of charge-displacement self-channeling as a mechanism to extend atomic lasers to higher quantum energy and then broadened this theory to the development of KeV-range laboratory x-ray lasers (1989c, 1994d).
NASA's Vision Mission for the Innovative Interstellar Explorer considered using optical-laser communication, as did the 1980s era TAU probe. It has also been proposed that higher frequency signals, such as lasers operating at visible light frequencies, may prove to be a fruitful method of interstellar communication; at a given frequency it takes surprisingly small energy output for a laser ...
The most recent generation of gamma-ray telescopes (2000s) have a resolution of the order of 6 arc minutes in the GeV range (seeing the Crab Nebula as a single "pixel"), compared to 0.5 arc seconds seen in the low energy X-ray (1 keV) range by the Chandra X-ray Observatory (1999), and about 1.5 arc minutes in the high energy X-ray (100 keV ...
The Psyche spacecraft is designed with solar electric propulsion, [26] [27] and the scientific payload includes a multispectral imager, a magnetometer, and a gamma-ray spectrometer. [ 27 ] [ 28 ] The mission is designed to perform 21 months of science.
A gamma ray burst (GRB) is the most powerful form of explosion in the known universe.They are produced when massive stars die, right before they turn into black holes, and were originally ...
In addition to detecting gamma rays, Explorer 11 was designed to map their direction with emphasis on the plane of the galaxy, the Galactic Center, the Sun, and other known radio noise sources; to relate the measurements to the cosmic-ray flux density and the density of interstellar matter; and to measure the high-energy gamma-ray albedo of the ...
