Project summary

In accordance with the purposes of ISTC in this Project it is suggested to form a new scientific and exploratory group from scientists and engineers, working in YerPhI, and who were previously engaged in defence programs of USSR. The main aims of this group will be development a new RF timing technique, which was proposed recently, that allows one to carry out time measurements with picosecond time resolutions. The proposed technique provides resolutions that are two orders of magnitude better than what existing methods can provide and can be used for a myriad of applications in science and technology. As a part of this development effort, we intend to investigate various configurations of this technique by means of Monte-Carlo simulation. We plan to construct a prototype device at Yerevan, test it at Yerevan and then possibly TJNAF (USA). The unique characteristics of this technique make it especially suitable for detection of lambda hypernuclei decay products at electron accelerators like CEBAF (TJNAF, USA) in a high intensity background of prompt particles. This is a characteristic that we plan to use to carry out experimental investigations of hypernuclei decay processes at CEBAF. This new timing technique can find different applications in science and technology, e.g., laser ranging techniques, fast time-resolving photochemistry etc.

The proposed Project corresponds to ISTC Introductions and aims and gives possibility to scientists from Yerevan Physics Institute (Armenia) engaged in military projects in the USSR during 1978-1990 for further collaboration with International Scientific Community.

Total Effort - 476 Person-months.


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.
