Abstract The radiation risk radiometer‐dosimeter (R3D)‐R2 solid‐state detector performed measurements at the European Space Agency EXPOSE‐R2 platform outside of Russian “Zvezda” module International Station (ISS) from 24 October 2014 to 11 January 2016. ISS orbital parameters were average altitude 415 km and 51.6° inclination. We developed special software used experimentally obtained formulas determine flux‐to‐dose ratio R3DR2 Liulin‐type deposited‐energy spectrometer. provide for first...
The dosimeter Liulin-MO for measuring the radiation environment onboard ExoMars Trace Gas Orbiter (TGO) is a module of Fine Resolution Epithermal Neutron Detector (FREND). Here we present results from measurements charged particle fluxes, dose rates and estimation equivalent at TGO Mars science orbit, provided by May 2018 to June 2022. period covers declining minimum phases solar activity in 24th cycle rising phase 25th cycle. Compared are values galactic cosmic rays (GCR) obtained during...
The aim of this paper is to present the time profile cosmic radiation exposure obtained by Radiation Risk Radiometer-Dosimeter during EXPOSE-E mission in European Technology Exposure Facility on International Space Station's Columbus module. Another make results available other teams for use their data analysis. a low-mass and small-dimension automatic device that measures solar four channels ionizing as well. main study include following: (1) three different sources were detected...
Abstract The aim of the paper is to present time profile cosmic radiation exposure obtained by risks radiometer-dosimeter (R3DR) during ESA exposition facility for EXPOSE-R mission (EXPOSE-R) in outside Russian Zvezda module International Space Station (ISS). Another make results available other teams use their data analysis. R3DR a low mass and small dimensions automated device, which measures solar four channels addition ionizing radiation. main measurements are: three different sources...
Ten-Koh is a 23.5 kg, low-cost satellite developed to conduct space environment effects research in low-Earth orbit (LEO). was primarily by students of the Kyushu Institute Technology (Kyutech) and launched on 29 October 2018 on-board HII-A rocket F40, as piggyback payload JAXA’s Greenhouse gas Observing Satellite (GOSAT-2). The carries double Langmuir probe, CMOS-based particle detectors Liulin spectrometer main payloads. This paper reviews design mission, specifies exact hardware used,...
The data from two Bulgarian-German instruments with the basic name "Radiation Risk Radiometer-Dosimeter" (R3D) are discussed. R3DR instrument worked inside ESA EXPOSE-R facility (2009-2010), while R3DR2 EXPOSE-R2 (2014-2016). Both were outside Russian Zvezda module on International Space Station (ISS). both used for calculation of neutron dose equivalent rate. Similar data, obtained by "BTNNEUTRON" ISS to benchmark R3DR/R2 analisys reveals that and values comparable in equatorial South...

Since June 2007 the Liulin-5 charged particle telescope, located in spherical tissue-equivalent phantom of MATROSHKA-R project onboard International Space Station (ISS), has been making measurements local energetic radiation environment. From 27 December 2011 to 09 March 2013 were conducted and outside MIM1 module ISS. In this paper dose rates, due galactic cosmic rays South Atlantic Anomaly trapped protons, measured during that period are presented. Particularly, rates fluxes for...
ExoMars is a joint ESA - Rosscosmos program for investigating Mars. Two missions are foreseen within this program: one consisting of the Trace Gas Orbiter (TGO), that carries scientific instruments detection trace gases in Martian atmosphere and location their source regions, launched on March 14, 2016; other, featuring rover surface platform, with launch date 2022. In 2018 TGO was inserted into circular Mars science orbit 400 km altitude. The dosimetric telescope Liulin-MO measuring...
