An electron lens is capable of producing focusing fields of controllable profile separately for proton and antiproton bunches. This makes it possible to neutralize collision effects. The pioneering experiments
A variety of microdomain textures were obtained depending on the energy density of the electron beam, the irradiation time, the dopant and the use of ion-beam thinning prior to electron microscopy. Proton-exchanged specimens are more stable than LiNbO3: Ti, which is in turn more stable than ...
Data on inclusive dielectron production are presented for the reaction p+p at 2.2 GeV measured with the High Acceptance DiElectron Spectrometer (HADES). Our results supplement data obtained earlier in this bombarding energy regime by DLS and HADES. The c
However, because of electron scattering this is not the case. Scattering is defined as an interaction of the incident electrons with the electrons and atoms in the specimen that causes a change of the electron trajectory and/or energy. The key concepts in describing scattering are the cross ...
(2021) 136:472 Page 3 of 28 472 In parallel, the activity concerning aerosols continued (using the external beam set-up as well) and it was in these applications that we first extensively used also Particle-Induced Gamma-ray Emission (PIGE) technique, complementing PIXE in the analysis of ...
Effect of electron beam (EB) irradiation is analyzed in low and high density polyethylenes (LDPE and HDPE, respectively) at different doses. Parameters as important as degree of crystallinity, melting or crystallization temperatures are dependent on the initial PE molecular architecture, which also ...
1 Introduction Muonium (M) is the bound state of a positive muon (μ+) and an electron, two particles devoid of internal structure. Therefore, and in contrast to hydrogen, theory and experi- ment with M can be compared free of finite-size and nuclear effects [1]. Testing bound state ...
Could a particle(proton, gold ion, electron) beam reach the surface of the moon, given current technology? Would the beam diffuse too much too scenter the regolith? Or would the beam have to be focused or continually refocused in order to achieve that? If so why can they do it with la...
electron gun 108 is positioned as to direct a sheet of electrons 109 radially between barrier 107 and extraction grid 114 and toward an electron catcher 110. The elements of FIG. 5 described as circular or annular are mounted symmetrically with respect to axis 35a of FIG. 2. They include ...
