On 4 January 2021, the Joint Institute for Nuclear Research received the patent for the invention “Laser inclinometer for long-lasting detection of the Earth surface angular inclination”. The authors are Yulian Aramovich Budagov and Mikhail Vasilevich Lyablin.

More about the invention

The invention refers to control and measuring technology. It can be used for precision measurements of Earth surface angular inclinations under thermal instability of the environment. The device comprises a stationary platform set on a rocky ground, a movable platform fixed on it with three identical positioners. A laser, a cuvette with a liquid, a focusing lens, a position-sensitive photodetector (PSPD) and a processing unit are placed on the movable platform. While the Earth surface is inclining, the laser beam reflected off the liquid changes its angular position, which is detected and analyzed by the PSPD and the processing unit. The change in ambient temperature entails unwanted laser beam shifts.

The scholarships are assigned for one year and intended to support activities of young scientists working on elementary particle and nuclear physics. The DLNP Expert Committee has resolved at its meeting to award the 2021 Bruno Pontecorvo Scholarship to Liudmila Kolupaeva and Maria Fomina.

Our heartfelt congratulations to the awardees! We wish you success and new scientific achievements!

At the seminar, a quantum-mechanical problem of a pair of identical particles interacting with a third particle via zero-range interactions was discussed. A complete description was given to a system of two identical fermions (bosons) and a third particle. Correct formulation of the problem was presented, and bound-state energies were calculated for various total angular momenta.
