Investigation of parameters of new MAPD-3NM silicon photomultipliers

In the presented work, the parameters of a new MAPD-3NM-II photodiode with buried pixel structure manufactured in cooperation with Zecotek Company are investigated. The photon detection efficiency, gain, capacitance and gamma-ray detection performance of photodiodes are studied. The SPECTRIG MAPD is used to measure the parameters of the MAPD-3NM-II and scintillation detector based on it. The obtained results show that the newly developed MAPD-3NM-II photodiode outperforms its counterparts in most parameters and it can be successfully applied in space application, medicine, high-energy physics and security.

CURRENT STATE OF THE SPACE ELEMENT BASE

The article considers the current state and the main promising areas of scientific and practi-cal developments in the field of radio electronics. For the space application of mechatronic systems, the microcircuits are characterized by multi-nomenclature low-volume indicators. To create a high-ly reliable electronic component base, it is necessary to ensure resistance to the fields of ionizing radiation from space, a wide range of temperatures and mechanical stresses. This requires the crea-tion of ECBs for space applications that are resistant to these external influencing factors.

Design, Application, and Verification of the Novel SEU Tolerant Abacus-Type Layouts

Radiation tolerance improvements for advanced technologies have attracted considerable interests in space application. In this paper, the single event upset (SEU) hardened double interlocked storage cell (DICE) D-type flip-flops (DFFs) with abacus-type time-delay cell are proposed and successfully implemented in our test chips. The layout structures of two kinds of abacus-type time-delay cells are illustrated, and their hardening effectiveness are verified by our simulations and heavy ion irradiations. The systematic heavy ion experimental results show that the applied abacus-type time-delay cells can reduce the SEU cross sections of DICE DFFs significantly, and even the SEU immune is observed for the full “0” data pattern. Besides, an apparent test mode dependency of the abacus-type hardened circuits is also observed. The results indicate that the nanoscale abacus structure may be suitable for space application in harsh radiation environment.
