Description

The object of research is radio-electronic components with enhanced stability to influence of ionizing radiation. The aim of project is the creation of database of modern electronic elements with enhanced stability to the effect of space ionizing radiation. One of the most important factors that affect the functioning of on-board electronic equipment in near-Earth and interplanetary space is known to be the influence of ionizing radiation fields of the space. During the last years a lot of new of radio-electronic elements have appeared. But not all types of integrated circuits can guaranteed to ensure the efficiency of spacecraft equipment under the effect of real levels of ionizing radiation. Since the problem of guaranteed providing radiation hardness on-board electronic equipments for long term and troubleproof operation of spacecraft is of current interest then it is important to create a database of contemporary radio-electronic components with enhanced stability to the effects of cosmic radiation. In the period under report the collection, accumulation and systematization of information on the radiation resistance of modern microelectronic products produced by the most well-known companies and which are suitable for the creation of on-board electronic equipment of spacecraft have been carried out. With the accumulation of information a systematization of devices on their functionality was performed and a computer database is created. The database is created by using "Microsoft Excel" program and has following form. The first page contains a list of devices class systematized on their functionality. A single cell corresponds to each class of products. Cells are active. When you select one of the items of the list then by clicking of mouse you are automatically taken to the page, which contains the selected devices. A separate page corresponds to each class of products collected in the database. Pages on which devices are systematized contain the following information: product name, the company-manufacturer, the functionality of the device, the basic parameters of the device, operating temperature range of the device, the value of the total cumulative dose, which does not lead to a change the original characteristics of the device, the device resistance to the effects of different types of ionizing radiation. Besides to each device a file attached, that has the format "pdf" or "htm", with a full description of the technical characteristics and functionality of the device. Opening of the file takes place automatically by pressing the mouse button. The files with description are in separate folders for each of the manufacturer and are attached to the database. The program "Excel" also allows to sort products by column on the page on the necessary parameters, on the manufacturer and so on. About 3,000 devices for different purposes, in all, are included in the database. The data obtained can be used in space instrumentation.
