From 27 to 29 October 2020, the 27th International Conference on Vacuum Technique and Technology was held in the virtual form at the Saint Petersburg Electrotechnical University "LETI". The Conference was organized by the Ministry of Science and Higher Education of the Russian Federation, Saint Petersburg Electrotechnical University "LETI" named after V I Ulyanov (Lenin), All-Russian Research Institute of Metrology named after D I Mendeleev, Institute of Problems of Mechanical Engineering of the Russian Academy of Sciences, Russian Scientific and Technical Vacuum Society named after Academician S A Vekshinskiy, Peter the Great Saint Petersburg Polytechnic University, Euro-Asian Cooperation of National Metrology Institutes (COOMET), National Metrology Institute (TUBITAK UME, Turkey).
The Conference was devoted to the latest achievements in vacuum physics, vacuum achievement and pressure measurement techniques, problems of tightness, surface treatment methods, and the creation of promising materials and coatings. Special attention was paid to the use of vacuum technologies in scientific research, in the nuclear and space industries, metallurgy and extractive industries. Issues of education, advanced training and training of highly qualified specialists were also discussed.
During 2 dedicated to all Russian scientists and specialists who have worked in the field of vacuum and cryogenic technology in different years," added Alexander Alexandrovich. His colleague Oleg Yurievich Skripochka wished success in all activities, including the expansion of mutually beneficial cooperation with organizations of the rocket and space industry. The president of the Russian Scientific and Technical Vacuum Society, Sergey Borisovich Nesterov read an excerpt from a document written by Academician S A Vekshinskiy: "The very fact of the birth of the electrovacuum industry led to the creation and study of a new technique -high vacuum technology".

"Our scientists have made a great contribution to the development of the vacuum industry. The Global energy revolution is now one step closer. In France, the construction of a building for ITERthe World's first new-generation thermonuclear reactor -has been completed. Now there is a new stage -the assembly of the installation itself. Russia is taking an active part in this international project." -President of the Russian Scientific and Technical Vacuum Society Sergey Borisovich Nesterov
In the plenary report, the Head of the Department of Electronic Instruments and Devices of Saint Petersburg Electrotechnical University Nikolay Nikolaevich Potrakhov touched upon the key issues of creating domestic X-ray tubes of a new type and radiation sources based on them (figure 2). Scientists of the Department of Electronic Instruments and Devices -one of the World leaders in the field of microfocus radiography -have developed a unique digital portable X-ray diagnostic complex for neonatology, which allows accurate diagnosis of newborns in non-specialized conditions in the shortest possible time and with a minimum dose of radiation.
N N Potrakhov also spoke about the prototype of a unique device for non-invasive cancer treatment, which in February 2020 was presented to the Head of the Federal Medical and Biological Agency of Russia Veronika Igorevna Skvortsova.
"Oncological diseases are treated by external radiation of the tumor. The source is located far from it, which makes it difficult to hit the target. We have developed an economical, safe and compact device, thanks to which the doctor will be able to accurately "shoot" a cancer from a short distance. The main element of the device is the source of X-ray radiation -a small X-ray tube that is delivered to the cancer through an incision made in the patient's body. The ability to bring the beam source as close as possible to the source of the disease will be a key advantage of the domestic device in comparison with foreign analogues." -Head of the Department of Electronic Instruments and Devices Nikolay Nikolaevich Potrakhov   "Changing the measurement mechanism will have a huge impact on the World. It will have an impact on accelerating innovation and reducing the cost of technological development. In this way, the science of measurement will adapt to the needs of future generations." -Head of the Laboratory at All-Russian Research Institute of Metrology named after D I Mendeleev Alexander Alexandrovich Chernyshenko During the sectional sessions, more than 100 specialists from Russia, Turkey and Ukraine presented 50 oral and poster presentations. The works were devoted to the latest achievements in vacuum physics, pressure measurement techniques, problems of tightness and the creation of promising materials, surface treatment methods, and the application of vacuum technologies in various industries.
During the Conference, scientists came to the conclusion about the need to expand research in the field of metrology of the total and partial pressures in the high and ultrahigh vacuum; leakage control; modeling of ground-based laboratory plants processes in vacuum in the development of rocket and space technology; low-temperature plasma for creation of new advanced materials.
When discussing the draft decision of the Conference, the scientists came to the conclusion that a clearly formulated strategy is necessary for progress in vacuum technology. The Conference participants agreed that in the field of production, it is necessary to ensure the creation of a size range of oil-free pre-vacuum pumps, wide-range vacuum meters and partial pressure analyzers. It is also necessary to develop such modern areas as analytical equipment, universal wide-range sensors, automation of pressure monitoring and process control.
As a result of the Conference, it was decided to create a register of organizations of the North-Western Federal District of Russia that develop, produce and use vacuum equipment in production.
"The country must maintain its position as an industrially developed power.
