Here, we present a novel method to measure the projected range of energetic protons impinging crystalline GaAs based on Raman spectroscopy. To validate the method, different proton energies were obtained using appropriate Al foils, an approach which has been properly justified. Finally, the spatial ...
damage distributionThe technique of cross-sectional transmission electron microscopy has been applied to obtain information on the projected range of protons and their damage distribution in gallium arsenide. The crystals were subjected to dosages of 1 1015 to 1 1017 protons cm2 and proton energies ...

The combined acceptance of the LHCb detector and the central barrel of the ALICE experiment covers the range of −5.2≲yc.m.s.≲0.7 in the case of the 2.76 TeV Pb beam — such a wide kinematic acceptance is not accessible in any collider experiment. Both detectors also offer ...
However, the high capital costs of proton therapy centers, which can range from USD 600 to USD 800 per square foot for multi-room facilities costing up to USD 250 million to build, limit its widespread adoption. Compact single-room systems, while more affordable, still require substantial ...
Roskosmos confirmed the start of the maneuver, but the vehicle likely went out of range of ground station in the Russian Far East before the completion of the firing could be confirmed.Orbital maneuversCLICK TO ENLARGEAfter a period of passive flight around the Earth, Briz-M re-started its ...
The exchange-correlation potential and ion-electron interactions were described by the generalized gradient approximation (GGA) and projected augmented wave (PAW) method56,57. The kinetic energy cut-off and the k-point meshes were set to 500 eV and 7×7×1, respectively58. The van der ...
Only protons in the central slice of ±1 µm around the symmetry plane within a vertical emission range of ±3° are shown. c, Angularly resolved contribution of different mechanisms to the acceleration cascade of the fastest protons (orange, CR; dark green, thermal, diffuse sheath field...
