Advantages of axially aligned crystals used in positron production at future linear colliders
X. Artru, R. Chehab, M. Chevallier +1
The characteristics of the electron-photon showers initiated by 2 to 10 GeV electrons aligned along the <111>-axis of tungsten crystals are compared with those for the amorphous tu…
Analytical calculation of Coulomb corrections to pair production at intermediate photon energies
R. N. Lee, A. I. Milstein, V. M. Strakhovenko
First correction to the high-energy asymptotics of the total photoproduction cross section in the electric field of a heavy atom is obtained with the exact account of this…
Linear to Circular Polarisation Conversion using Birefringent Properties of Aligned Crystals for Multi-GeV Photons
NA59 Collaboration, A. Apyan, R. O. Avakian +27
We present the first experimental results on the use of a thick aligned Si crystal acting as a quarter wave plate to induce a degree of circular polarisation in a high energy linea…
Coherent Pair Production by Photons in the 20-170 GeV Energy Range Incident on Crystals and Birefringence
NA59 Collaboration, A. Apyan, R. O. Avakian +27
The cross section for coherent pair production by linearly polarised photons in the 20-170 GeV energy range was measured for photon aligned incidence on ultra-high quality diamond…
Emission of polarized photons from unpolarized electrons moving in crystals
V. M. Strakhovenko
Radiation emitted by unpolarized high-energy electrons penetrating crystals may be linearly polarized. This occurs when the particle velocity makes an angle, with respect to some m…
