Спектрометрический алмазный детектор потоков ионизирующего излучения для транспортных космических систем
The review highlights the parameters of multilayer diamond detector for monitoring space radiation based on CVD diamond technique. The paper specifies the results of measuring charge output spectrum of single and double layer diamond detectors. Diamond detector serves to on-board radiation monitoring systems of spacecraft having lifetime increase in up to 20?25 years. The use of a diamond detector multi-layer structure makes it possible to enhance the amplitude of charge output spectrum, to expand the detector dynamic range, as well as to improve the accuracy and information content of radiation monitoring systems.
Ensuring effective control instrument, development of new methods and improving the accuracy of geophysical instrumentation devices used in exploration of mineral resources is one of the important problems in the mining industry. This paper discusses current research and options for optimizing the electrical and structural parameters monitoring devices neutron yield borehole neutron generator for the respective systems of neutron-neutron logging, for which we have developed and successfully used diamond detectors. Further expansion of the applications of diamond materials in new areas of the economy, especially in instrumentation, will ensure a more rational and efficient use of natural resources. The results of the research staff monitor devices for monitoring the neutron yield borehole neutron generator systems for neutron-neutron logging including for replacement to the original diamond detectors domestic production. - investigation of the influence of environmental parameters on the downhole tool (diamond detector temperature stability in a temperature range of from 20 to 140 ° C). - Research linearity of conversion of fast neutrons to monitor the complex by measuring the deviation of the output signal amplitude in the temperature range from 20 to 140 ° C.
The power dependency of cosmic rays energy distribution over a wide energy range shows their degradation origin. Analysis of the cosmic rays spectra in comparison with the typical degradation spectra of cascade processes makes possible to describe the kinetics processes of origin and propagation of cosmic rays, in particular the differential loss energy probabilities, the cascade role, and to estimate the energy and number of primary cosmic rays particles.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
