Postgraduate of LAPLAS has internship in Institute of high energy physics at Chinese Academy of Sciences


A postgraduate students of the LAPLAS Institute Jaroslav Shashkov has had an internship in the Institute of high energy physics, Chinese Academy of Sciences (IHEP-CAS).

In addition to the internship Yaroslav managed to hold talks on cooperation with Chinese colleagues, to report on scientific developments and to participate in an international conference.

Being actively involved in research projects, he discussed the cooperation in the development of superconducting (SC) microwave cavities for the project of the Circular electron positron collider with colleagues from the Institute of high energy physics. This interaction can be very useful and fruitful because in recent years China has taken a big leap in the field of accelerator technologies and SC cavities. SC cavities are the basic components of a large number of such MegaScience projects like the Large Hadron Collider, the European x-ray free electron laser XFEL and a dozen other accelerators. These facilities allow to discover new laws of physics, to study the structure of proteins and cells to create new drugs, create new materials.

During the visit to the Peking University Yaroslav made a report on the areas of interest of MEPhI in general and the LAPLAS Institute in particular, spoke about the obtained scientific results, and got acquainted with the developments that are underway in the laboratories of the Peking University.

At the International conference on superconducting microwave cavities, which took place in Lanzhou (Central China), Jaroslav Shashkov made a report on the optimization of the geometry of the nine-cell microwave cavity to increase the efficiency of suppression of the waves of higher type. Jaroslav received a grant from the conference organizers to participate in it.

– My report caused a great interest of the colleagues. In fact waves of higher type lead to negative consequences for the beam and limit the maximum beam current; the development of new ways to reduce waves’ impact on the beam will increase the quality and current of a beam. It was very important for me to make a report at the conference because less than 1000 people in the world are engaged in the development of superconducting cavities, while the conference was attended by over 300 people, that is, such conferences allow to maintain contact with almost the entire community. It was useful to listen to the reports of colleagues – many of them were focused on the progress in the construction and launch of accelerators in the United States, Europe, China, Japan, as well as the use of new materials for cavities, the development of new types of geometries of SC cavities resonators, the so-called Crab cavities.

Every day in China brought new knowledge that I learned from colleagues from the Institute of high energy physics, the Peking University, participants of the conference, and during a tour in the Institute of Modern Physics (organized in the framework of the conference) and familiarity with their project Nuclear Fission Energy Program - ADS Transmutation System - a proton accelerator with beams of MW power, which will allow to convert nuclear waste into a safe materials.
