MOSCOW, 11 Mar — RIA Novosti. Joint Institute for nuclear research in Dubna joined the medical collaboration CERN Medipix-4, in which the Russian physicists will take part in the development of “smart” radiation detectors that can recognize substances on the tomograms, the press service of MIPT.
“Official participation in collaboration Medipix-4 is not only a recognition of the successful work of the JINR group, but also a tool for more efficient scientific work. Especially attractive that it has become possible not only to use the Medipix chip for creating hardware, but also to participate directly in their development,” said Alexey Zhemchugov, researcher, MIPT and JINR.
In early March, CERN and JINR signed an agreement to establish a collaboration Medipix-4, which included the European organization for nuclear research and their Russian colleagues from the Moscow Institute of physics and the JINR.
In this project, scientists will develop a whole family of chips, pixel detectors of ionizing radiation. These unique analog-to-digital chip will use the latest achievements of microelectronics and contain more than 65 thousand independent channels for amplifying and digitizing the electrical signals. The pixel detector is in structure similar to the matrix standard digital camera, but it differs from it in much higher sensitivity and much lower noise level.
Future and existing generations of Medipix chips are “smart” devices that can not only measure power and other parameters of ionizing radiation, but also to process the signal before it goes into the computer. The new iteration of this device will be an evolutionary — Russian and European engineers and physicists will not try to “discover America” and Medipix just transferred to a new process technology that will reduce the dissipation and increase the performance of the chips.
The main feature of Medipix is that the detectors on its basis allow not only to detect the presence of certain radioactive sources, but also to determine the energy of the emitted particles with them. This allows us to obtain x-ray image ultra high quality, but also to determine the chemical composition of the samples for tomography, to study the microstructure of the tissues of living organisms and to determine the proportion of different substances in them.
Such cooperation and the Medipix chip will not for scientists from JINR to the development of something new — our scientists are actively developing devices based on those chips since 2008. One of the products of these developments is the system for monitoring of radiation background on the detector ALTAS, working in the framework of the Large hadron Collider.Related posts:
