Project summary

The proposed project envisions experimental measurements to assess the feasibility of using resonant acoustic stimulation of a piezoelectric crystal to enhance the radiation produced by a beam of electrons which is directed along one of the major planes or axes of the crystal. If successful, the intensity of this channeling radiation will be multiplied many-fold, rendering it eminently suitable for use as an intense but inexpensive source of monochromatic and directed X-rays for many applications.

This project will allow the development of a method to enhance channeling radiation by means of the excitation of bulk hypersonic oscillations in a crystal. This method is original, and has never before been quantified. The scientific part of the project will include studies of the effects of these GigaHertz hypersonic vibrations on both the spectral and angular characteristics of the channeling radiation as well as on its intensity.

The measurements will be carried out with the injector linac of the 6-GeV electron synchrotron of the Yerevan Physics Institute. This linear accelerator supplies electron beam energies Ee from 10 to 50 MeV. Theoretical calculations of this resonant enhancement of channeling radiation will be carried out in tandem with the experimental measurements. In fact, preliminary measurements and calculations have both been performed already, and both show great promise for the eventual success of the project as a viable technological development capable of transfer to the industrial sector.

The range of practical applications for this technology is extremely wide. Such applications include its use in medical imaging, notably for angiography, and for sub-micron lithography of semiconductor chips. A number of other possible applications are indicated in the text.

The presenting Work Plan is an output of A100d(PDG)-99 Grant which was approved by ISTC using USA financial support. One of the main goals of mentioned Grant was the thorough revision of the Project A100 and its development.

The project is drafted in accordance with the ISTC instructions. It combines fundamental and cutting-edge scientific research with economically promising technological potential, and creates an opportunity for a substantial number of scientists and technical personnel, who were engaged earlier in the development of arms and military facilities, to work in their home laboratories on a project with peaceful objectives. The project is designed for a duration of 24 months, by which time it is hoped that larger enterprises will grow from it.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
