The Experiment at LUE-75

NEWS & PROJECTSNational lab scientists publish approximately 30% of scientific publications in RA.Most of the publications appear in high-impact factor journals. More than 60% of overall citations to papers published by scientists from Armenia belong to the AANLThe Experiment at LUE-75The scientists from Dubna, who are currently operating the last phase of the experimental investigation with the colleagues at AANL Experimental Physics Division, headed by Professor Hrachya Marukyan, note that during the collaboration with the group from AANL there has been a significant stride forward in the experiment. They stress the contribution of A. Hakobyan, A. Babayan and their colleagues mention that although AANL accelerators were thought to have stopped operating for a long time, it was the accelerator LUE-75 at AANL that produced the unique regime necessary for the experimental results.​



A group of physicists from the Joint Institute of Nuclear Research, Dubna, Russia, managed by Yuri Davydov, Head of the Scientific Division of Multiplicity Hadron Processes of Dzhelepov Laboratory of Nuclear Problems, with the specialists from the Experimental Physics Division at AANL have been conducting research on the calibration of CsI crystals at the electron linear accelerator LUE-75 since 2014. These crystals have to be used in the prototype calorimeter of the Mu2e experiment at Fermilab, USA. When the problem of calibration of the elements of the calorimeter arose, the accelerator LUE-75 at AANL was chosen as the best option from a number of other alternatives. The extremely low-intensity electron beams are obtained only in several scientific centres worldwide, in Japan, China and Italy. However, the range of energy from 10 to 75 MeV, necessary for the successful completion of the set of data, obtained by Mu2e collaboration in Frascati (Italy), for the energy range 80-120 MeV was available only at the AANL accelerator, injector for the electron synchrotron ARUS.
