He was one of the creators of the long-range detection radar and the Soviet synchrophasotron in Joint Institute for Nuclear Research in Dubna.

On September 30, 1916, Mintz announced his first invention - "A system for paralyzing the operation of an enemy radio station", based on the use of frequency modulation.

The Mintsev family, fearing reprisals, hastily left the city, but Alexander flatly refused to leave.

In 1922, he created the country's first army tube radiotelegraph station, which was put into service in 1923 under the symbol "ALM" (Alexander Lvovich Mints).

[4] In August 1923, Mints was appointed head of the Scientific Testing Institute of the Military-Technical Council of Army Communications (SRI VTSS RKKA (Russian: НИИ ВТСС РККА)), created in April of the same year on the basis of the Military Radio Engineering Laboratory (VRTL).

[5] Under his leadership, the first radio broadcasts of concerts, operas and performances from theater halls, as well as newsreels from streets and squares, were carried out.

This team became the basis of the "Powerful Radio Construction Plant named after the Comintern", which included several factories, as well as scientific, design and installation organizations.

On May 7, 1938, shortly after returning from a business trip to the United States, the chief engineer of NII-33 of the People's Commissariat of Defense Industry, Mints, was arrested again, now on charges of participating in an "anti-Soviet right-wing Trotskyist organization, on whose instructions he carried out sabotage work at the plant No.

[3] On July 10, 1941, he was released by personal order of Josef Stalin as the war began, and in Kuibyshev it was decided to create a medium wave radio broadcasting station with a powerful for those times - 1200 kW, the transmissions of which could be received in the occupied territory.

In the same year, to solve scientific and engineering problems within the framework of the Soviet atomic project, which was supervised by Lavrentiy Beria, Laboratory No.

In 1956, by the Decree of the Central Committee of the CPSU and the Council of Ministers of the Soviet Union "On Missile Defense", Mints was appointed one of the main designers of the long-range detection radar.
