Circuit engineering methods for ensuring ECB resistance to the effects of heavy charged particles

The paper considers circuit engineering methods for protecting the electronic component base from the effects of heavy charged particles. One of the main methods is to increase the capacity of the device, which leads to an increase in the capacity of diffusion regions and a decrease in the frequency of single events. The structure of a capacitor is shown, which is connected to various nodes of the circuit to increase the sensitivity of the capacitance of the node. The article focuses on the method of using active RC circuits in the feedback circuit of a storage device cell. The advantages and disadvantages of the methods of using a storage device cell with internal redundancy are noted. The paper shows that the use of circuit engineering methods will provide the required level of fault and fault tolerance to the effects of heavy charged particles.

Methods for detecting and correcting errors in irregular structures under the influence of heavy charged particles

The paper considers methods of increasing the durability of radio-electronic equipment in space, namely, methods of detecting and correcting errors during the action of the HCP. Currently, redundancy methods are used to ensure durability, when two or three processors work in parallel in the system, and a special node compares the results of their work. If the results do not match, an error signal will be generated, and the system will begin to perform actions to correct it. The article describes and classifies the main circuit, structural-functional, algorithmic methods for detecting and correcting errors. It is shown that circuit solutions lead to an increase in the crystal area. Therefore, the problem arises of ensuring radiation resistance with a minimum increase in the crystal area.

Sensitivity analysis and test results of the electronic component base to the effects of heavy charged particles

The work is devoted to the study of the sensitivity of the electronic component base (ECB) to the effects of heavy charged particles. At the same time, the degree of sensitivity is distinguished depending on the functional group of ECB products to the effects of ionization radiation from outer space and on the design and technological design of ECB products. The paper presents the characteristics and conditions for the use of ECB in the radio-electronic equipment of outer space to ensure minimal sensitivity to the effects of ionization radiation and to the thyristor effect. After the sensitivity analysis of ECB products is carried out, a preliminary selection of ECB is performed, requiring testing. The article discusses the criteria for determining the ECB that requires testing and is possible to use without testing. The methods of increasing the durability of radio-electronic equipment of space equipment and the directions of optimization of the methodology of analysis of ECB lists are determined.

RESULTS OF TESTS OF CONTROL SYSTEMS ON EXPOSURE TO HEAVY CHARGED PARTICLES

The article discusses the results of the ERI tests for the effects of heavy charged particles. The data that arose during the irradiation of single radiation effects are presented. During the irradi-ation of the samples, the measurement of the integral flux (fluence) of ions was carried out using track detectors. To conduct the tests, technological equipment was used that implements the operating modes of the tested analog-to-digital converter and provides measurement of the parameters-the validity criteria. When irradiating samples with ions, the occurrence of a thyristor effect, cata-strophic failure and functional interruption effects were not recorded.

DEVELOPMENT OF FAIL-SAFE CONTROL SYSTEMS AGAINST HEAVY CHARGED PARTICLES OF OUTER SPACE

This article discusses the development of effective methods and tools for assessing the fault tolerance of logical circuits, the mechanism of logical masking, the development of the route of re-synthesis of combinational circuits, methods for increasing fault tolerance. A method of iterative circuit modification is proposed, due to an increase in the level of logical masking of the circuit.

DEVELOPMENT OF MEANS FOR MONITORING THE PARAMETERS OF MICROCHIPS FOR ASSESSING RADIATION RESISTANCE

This article discusses the technical means of monitoring the performance of a special-purpose ECB for experimental evaluation of radiation resistance, in the absence of test measuring equipment that allows you to control the areas of the most degraded degradation when exposed to ionizing radiation and heavy charged particles of outer space.

Production of heavy charged particles in proton-proton ultraperipheral collisions at the Large Hadron Collider: survival factor

Ultraperipheral collisions of high energy protons are a source of approximately real photons colliding with each other. Photon fusion can result in production of yet unknown charged particles in very clean events. The cleanliness of such an event is due to the requirement that the protons survive during the collision. Finite sizes of the protons reduce the probability of such outcome compared to point-like particles. We calculate the survival factors and cross sections for the production of heavy charged particles at the Large Hadron Collider.
