Displacement of collider beam focuses caused by various seismic sources was discussed.A method is proposed for calculating the beam focus displacement due to the passing seismic waves with allowance for the length of the area of beam preparation for collisions, frequency of the seismic wave, and its velocity dependence on the frequency.
Today, our laboratory received honoured guests, the Ambassador of Italy to the Russian Federation Mr Pasquale Q. Terracciano accompanied by the First Counsellor of the Italian Culture, Science, and Language Promotion and Consular Network Coordination Office Mr Walter Ferrara, and the Scientific Attaché of the Italian Embassy to Russia Mr Aldo Spallone and the delegation of the Italian National Institute for Nuclear Physics(Istituto Nazionale di Fisica Nucleare - INFN) headed by INFN PresidentMr Fernando Ferroni accompanied by the INFN Vice-President Antonio Masiero. The guests visited the Memorial Study of Bruno Pontecorvo.
On 6 July 2018, at the session of the DLNP Dissertation Council Petr Igorevich Smolyansky defended the dissertation “Study of gallium arsenide pixel detectors based on the Timepix microcircuit” (speciality 01.04.01 “instruments and methods of experimental physics”)for getting the decree of the Candidate of Sciences in Physics and Mathematics.
We heartily congratulate Petr on the successful defence of the dissertation and wish him further success and creative achievements!
At the seminar, consideration was given to advantages and drawbacks of methods for measuring coordinates of the laser beam center and determining the range and amount of laser beam displacements using the quadrant photoreceiver, CCD matrix, and dividing plates.
The results of the double beta decay investigations were reported. The investigations are carried out with the TGV-2 andObelix low-background HPGe spectrometers at the Modane underground laboratory (France) at a depth of 4800 m water equivalent. The main goal of the measurements with the 32-detector spectrometer TGV-2 is direct detection of the two-neutrino double electron capture in the 106Cd decay.
Today, on 20 June 2018, a scientific seminar was held at the JINR Scientists’ Club to celebrate the 90th birthday of Prof. S.M. Bilenky. The seminar was organized by the Dzhelepov Laboratory of Nuclear Problems and the Bogolyubov Laboratory of Theoretical Physics.
