68. Radiation and pair production in oriented crystals: innovative application to future particle accelerators and detectors

LAURA BANDIERA

invited

It has been known since decades that the alignment of a beam of high-energy e- or photons with particular crystal direction involves a huge increase of radiation emission or pair production probability, respectively. While crossing an oriented crystal, such penetrating particles experience an electromagnetic field so strong that it leads to a huge enhancement of the e.m. shower development...

oral

This work is devoted to the problem of acceleration of charged elementary particles and ions in air. This work is a continuation of a cycle of research in a new field of acoustoplasma physics, created by the founder of the Institute of Applied Problems of Physics of the NAS of the RA, Academician A.R. Mkrtchyan.
For experimental research, in the IAPP NAS RA developed and created unique...

26. A 500 MeV positron beam for channeling experiments at the Mainz Microtron MAMI

invited

A beam line for 500 MeV positrons is under construction at the applied physics area of the Mainz Microtron MAMI. Positrons will be created by pair conversion of bremsstrahlung, produced by the 855 MeV electron beam of MAMI in a 10 m thick tungsten converter target, and energy selected by an outside open electron beam-line bending magnet. - Results of channeling calculations of 500 MeV...

84. On (110) planar channeling experiments with 500 MeV positrons in silicon single crystals

oral

Experiments with the 500 MeV positron beam under construction at the Mainz Microtron MAMI will be proposed to study the (110) channeling process in silicon single crystals. Simulation calculations were performed which are based on the double differential cross-section as function of the momentum transfer q and the energy transfer W to a bound electron. In this framework, also the energy...

Channeling of low-energy ions in carbon nanotubes taking into account many-body effects

A.V. Stepanov, A. S. Sabirov, A. A. Shemukhin

The use of carbon nanotube (CNT) bundles instead of masks has the advantage of allowing the ion beam to be controlled in three dimensions by manipulating the nanotubes. Due to this, it becomes possible to direct the ion beam to hard-to-reach places, for...
