The basic formulae for the damping of the energy and betatron oscillations are derived. The results are applied to a number of examples of different lattice designs in which radiation damping effects are important. Methods of modifying and measuring the damping rates are also discussed.

اندرکنش دینامیکی خاک - سازه یکی از پایه های مهندسی زلزله را تشکیل می دهد که کاربردهای قابل ملاحظه ای در آنالیز و طراحی سازه های مهندسی عمران دارد. به طور کلی اندرکنش دینامیکی خاک - سازه را می توان بر مبنای منبع تحریک به دو گروه مساله تشعشع (radiation problem) ومساله پراکندگی (scattering problem) تقسیم نمود. گروه اول بارهای خارجی اعمال شده از شالوده ها به خاک (ماشین آلات مرتفع) و گروه دوم پاسخ پ...

The radiation damping rate of plasmon resonances in pairs of spherical gold nanoparticles is calculated. The radiative line width of the plasmon resonance indicates significant far-field coupling between the nanoparticles over distances many times the particle diameter. The radiation damping of the coupled particle-plasmon mode alternates between superradiant and subradiant behavior when the pa...

In previous work the authors analysed the global properties of an approximate model of radiation damping for charged particles. This work is put into context and related to the original motivation of understanding approximations used in the study of gravitational radiation damping. It is examined to what extent the results obtained previously depend on the particular model chosen. Comparisons a...

Plasma outflows from gamma-ray bursts (GRB), pulsar winds, and relativistic jets radiate high energy emission. However, the radiation damping effect is ignored in conventional simulations. In this letter, we study the radiation damping effect on particle acceleration via Poynting fluxes in two-andhalf-dimensional particle-in-cell (PIC) plasma simulation with magnetized electron-positron plasmas...

A qumi-classicalmethod is developed to calculate the radiation damping of a relativisticparticle in a straight, continuous focusing system. In one limiting case where the pitch angle of the particle OPis much larger than the radiation opening angle l/y, the radiation power spectrum is similar to synchrotron radiation and the relative damping rate of the transverseaction is proportional to the r...

A quasi-classical method is developed to calculate the radiation damping of a relativistic particle in a straight, continuous focusing system. In one limiting case where the pitch angle of the particle θp is much larger than the radiation opening angle 1/γ , the radiation power spectrum is similar to synchrotron radiation and the relative damping rate of the transverse action is proportional to...

Evidence of coherent synchrotron radiation has been reported recently at the electron storage rings of several light source facilities. The main features of the observations are (i) a radiation wavelength short compared to the nominal bunch length, and (ii) a coherent signal showing recurrent bursts of duration much shorter than the radiation damping time, but with spacing equal to a substantia...

Depolarization of a polarized electron beam injected into a damping ring is analyzed by extending calculk tions conventionally applied to proton synchrotrons. Synchrotron radiation in an electron ring gives rise to both polarizing and depolarizing effects. In a damping ring, the beam is stored for a time much less than the time for self polarization. Spin &p radiation may therefore be na glecte...
