Electron cooling application for luminosity preservation in an experiment with internal targets at COSY In calculations of the proton and deuteron beams we concentrated on cluster, atomic beam, storage cell and pellet targets at ANKE experiment mainly. In these calculations electron and stochastic cooling...
Ifwetake the limit of vanishing quadrupole length lquad ! 0, while holding the integrated gradient k = jKjlq constant, we arrive at the matrix for an idealized `thin-lens' quadrupol...P. Schmueser, "The electron proton colliding beam facility HERA," Nucl. Instrum. Meth., vol. A235, ...
High-resolution electron microscopic studies of doped and proton-exchanged lithium niobates (LiNbO3: Fe, Ti, H) are described. 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...
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 ...
The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) at CERN aims to develop a proof-of-principle electron accelerator based on proton driven plasma wake-field acceleration. The core of AWAKE is a 10 metre long pla... S Mazzoni,L Jensen,E Gschwendtner,... 被引量: 5...
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 ...
As it is, Advanced Oncotherapy’s LIGHT solution is only 78 feet long, which can be halved by doubling the beam back on itself while maintaining maximum energy output. The accelerator produces a proton beam of 230 megaelectron volts traveling at 60% of the speed of light, comparable with ex...
Behaviour of an accelerating beam of electron. If a beam of electrons starts to accelerate from rest due to a uniform electric field in vacuum will the electrons feel any mutual repulsion or attraction? Will the beam first expand then contract? If yes, how does this happen? This was a ques...
On the other hand, the second set anticipates that the singularity of the circulation is spin-orientation-dependent and can disappear, especially for a relativistic paraxial electron beam with spin parallel to the propagating direction. These contradistinctive predictions suggest that a relativistic ...
