Resonant coherent excitation of 390 MeV/u Ar ions planar channeled in Si crystals
Resonant coherent excitation of the 1s electron to n 2 states in a hydrogen-like ion was studied through measurements of the survived fraction of 390 MeV/u Ar17 planar channeled in a Si crystal. Adopting a totally depleted Si surface barrier detector as a target crystal, the charge state of the individual emerged ion was measured in coincidence with the energy deposition in the target. By cha...
متن کاملBremsstrahlung from Electrons and Positrons in Peripheral Relativistic Heavy Ion Collisions
We study the spectrum of the bremsstrahlung photons coming from the electrons and positrons, which are produced in the strong electromagnetic fields present in peripheral relativistic heavy ion collisions. We compare different approaches, making use of the exact pair production cross section in heavy ion collisions as well as the double equivalent photon approximation. 25.75.-q,13.40.-f Typeset...
متن کاملCoherent Bremsstrahlung at the Bepc Collider *
Coherent bremsstrahlung (CBS) is a specified type of radiation at colliders with short bunches. In the present paper we calculate the main characteristics of CBS for the BEPC collider. At this collider dN γ ∼ 3 · 10 8 dE γ /E γ photons of CBS will be emitted for a single collision of the beams in the energy range E γ < ∼ 240 eV. It seems that CBS can be a potential tool for optimizing collision...
متن کاملCoherent bremsstrahlung in a bent crystal
At passage of an ultra-high-energy particle through a bent crystal coherent bremsstrahlung is emitted but with characteristic frequencies distributed continuously, in relation with the crystal bend profile. For practical crystals, such radiation can be calculated by the stationary phase approximation technique. The radiation spectrum averaged over the impact parameters is evaluated. Its charact...
متن کاملThe Radiation of the Positrons Channeled between the Planes of a Crystal*
The case of the channeling radiation for electrons was considered in the previous work [Il. Th e use of the electrons for producing and detecting this type of radiation has the advantage that available electron beams have much smaller transverse phase space than thoseof the positrons. In addition, the intensity of radiation of electrons is somewhat larger in comparison to the positrons simply d...
