Project summary

The global purposes of the Project are the research, development, elaboration of technological processes and production of the experimental samples of microstrip silicon detectors and microstrip gas chambers with large area for high precision tracking system of general-purpose experimental detector ATLAS for studies of fundamental properties of matter at Large Hadron Collider (LHC), designed at CERN.

In accordance with requirements, worked out by international body of scientists of ATLAS Collaboration, this Project aims at achievement to fulfil the following tasks:

- research and improvement of the methods of the manufacturing of microstrip detector structures for reliable and stable production of detectors with high level parameters with silicon of high resistivity of n-type conductivity and experimental studies of silicon with p-type conductivity;

- studies and choice of the type of substrate for microstrip gas chambers as the most decisive detector element with surface resistivity 1012- 1013 Ohm/sq. and acceptable gas gain and signal to noise ratio;

- studies of the change of parameters of silicon detectors at high radiation (integrated neutron fluence up to 1014 n/ at the relatively low temperatures (<0° C), and search for the methods to increase radiation hardness of detectors;

- creation of complete technological line for production of experimental samples of detectors with parameters required, with relatively high yields of good detectors in manufacturing and their high long-term stability;

- research and development of silicon detectors, integrated with front-end readout electronics.

As a result of the Project, 600 experimental microstrip detectors of few types will be produced and tested in accordance with specifications of ATLAS experiment.

The main technological studies will be worked out in NIIIS, where the basic equipment and experienced specialists are located. Main tests for radiation hardness will be done in VNILEP, where the installations for neutron, proton, electron and gamma irradiation and corresponding specialists exist.

As the detector parameters, required for ATLAS experiment are extremely high, detectors of such type are planning to be used in other experiments of high energy physics, in experiment DO in FERMILAB (USA), for example, and in other regions of sciences, such as high resolution, high sensitivity x-ray detection for medical applications or for non-destructive test apparatus both with excellent time and space resolution as well as immediate imaging. It gives possibilities for future development of research activities in detectors studies and production, in accordance with ISTC's objectives.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
