Google Share on Facebook proton resonance [′prō‚tän ′rez·ən·əns] (spectroscopy) A phenomenon in which protons absorb energy from an alternating magnetic field at certain characteristic frequencies when they are also subjected to a static magnetic field; this phenomenon is used in ...
The physical advantages of proton irradiation are the characteristic energy deposition peak (‘Bragg peak’), behind which the energy drops towards near zero, minimizing dose deposition (“exit radiation”) in the tissue behind the Bragg peak [53]. Thereby, protons can deliver similar radiation dos...

Charged particles can be accelerated to high energies by collisionless shock waves in astrophysical environments, such as supernova remnants. By interacting with the magnetized ambient medium, these shocks can transfer energy to particles. Despite increasing efforts in the characterization of these shocks...
Kαradiation. The Fe K-edgeXAFS spectrawere collected at the U7Cbeamlineof Hefei NationalSynchrotron RadiationLaboratory (NSRL). The storage ring of NSRL was operated at 0.8GeV with a maximum current of 300mA. The hard X-ray beam was from a threepole superconducting Wiggler with amagnetic ...

Proton therapy with spot scanning: The Rinecker Proton Therapy Center in Munich. Part 2: Technical & physical aspects The Rinecker Proton Therapy Center (RPTC) in Munich is about to introduce into clinical radiation therapy, a 2D scanning technique (spot scanning) of a single proton pencil beam...
The x-axis points from the IP to the –2– a transition radiation tracker, which also provides information for electron identification. Each tracking detector consists of a central barrel and two endcap sections. The electromagnetic calorimeter is a sampling device made of lead absorbers with liq-...
The structures of Pt-Fe-N-C were examined by an X-ray diffractometer (PANalytical, X’pert Pro) equipped with a graphite monochromator and a Cu Kα radiation source. Bulk and surface compositions were evaluated through inductively coupled plasma mass spectrometry (Agilent Technologies, Agilent ...
