On the 14th of December researchers from Italy Dr. Graziano Venanzoni and Antonio Anastasi have made reports on recent results of preparation for the experiment “g-2”. The event was held in the framework of the mini-session of the international workshop “Advanced Accelerator & Radiation Physics” in MEPhI.

Experiment “g-2” is conducted in Fermilab (USA) and is aimed at determining the magnetic moment of muons and, thus, testing assumptions about the Standard model.

Guests, representing that day the National Institute for Nuclear Physics (INFN) from Italy, spoke about the purpose of the experiment, about its role and tasks. In g-2 INFN is developing a laser system for calibration of colorimeters – the main diagnostic element of the installation. This task includes modeling of the experiment, determination of desired parameters of the calibration system from the generated model and preparation of hardware for it.

For this purpose it is necessary to determine how charged particles pass through the crystal: what energy losses they undergo, and what these losses cause – Italian colleagues plan to receive help with these issues from researchers of MEPhI from the Department № 67, who work on interaction of charged particles with crystals.

In particular it became possible because the laboratory XLab Frascati (INFN, the head is Professor of the MEPhI S. Dabagov) are actively involved in the project from the very beginning, and also due to the recently signed agreement on cooperation between MEPhI and INFN.
