Structured Targets and the Landau - Pomeranchuk - Migdal Effect
نویسنده
چکیده
The Landau-Pomeranchuk-Migdal effect is the suppression of Bethe-Heitler radiation caused by multiple scattering in the target medium. In this paper, the quantum treatment given earlier for finite but homogeneous targets is extended to structured targets. It is shown that radiators composed of separated plates or of a medium with a varying radiation length can exhibit coherence maxima and minima in their photon spectra.

Light-cone path integral approach to the Landau–Pomeranchuk–Migdal effect and the SLAC data on bremsstrahlung from high energy electrons
We analyze the recent data of the SLAC E-146 collaboration [11] on the Landau-Pomeranchuk-Migdal effect for bremsstrahlung from 8 and 25 GeV electrons within a rigorous light-cone path integral approach previously developed in Refs. [14, 16]. Numerical calculations have been carried out treating rigorously the Coulomb effects and including the inelastic processes. Comparison with the experiment...
متن کاملThe Landau-Pomeranchuk-Migdal effect and transition radiation in structured targets
The radiation from high-energy electrons is investigated for the case when a target consists of several separated plates. The spectrum of radiation is considered in the region in which the bremsstrahlung is under influence of the multiple scattering of a projectile (the LPM effect), the polarization of a medium and the hard part of the boundary radiation contribute. In this region the general e...
متن کاملThe Landau-Pomeranchuk-Migdal effect in a thin target
The Landau, Pomeranchuk, Migdal (LPM) effect (suppression of the bremsstrahlung from high energy electron due to a multiple scattering of an emitting electron in dense media) is considered for the case when thickness of a target is of the order or less than the formation length of radiation. The effects of the polarization of a medium and transition radiation are taken into account as well. Qua...
متن کاملLandau-Pomeranchuk-Migdal effect for multihundred GeV electrons
Experimental results for the bremsstrahlung energy loss of 149, 207, and 287 GeV electrons in thin Ir, Ta, and Cu targets are presented. For each target and energy, a comparison between simulated values based on the Landau-Pomeranchuk-Migdal ~LPM! suppression of incoherent bremsstrahlung is shown. For the electron energies investigated, the LPM effect enters the quantum regime where the recoil ...

We analyze within the light-cone path integral approach [4] the recent CERN SPS data [19] on the Landau-Pomeranchuk-Migdal effect for photon bremsstrahlung in quantum regime from 149, 207, and 287 GeV electrons. Calculations have been carried out treating accurately the Coulomb effects and including the inelastic processes. Comparison with experiment is performed accounting for multi-photon emi...
