The project was won during the 1st CALL FOR OUTLINE PROPOSALS UNDER THE PLAN FOR EUROPEAN COOPERATING STATES (PECS) IN BULGARIA, September 2015
The Active neutron spectrometer and dosimeter (ADRON-EM) is in the list of the Russian led instruments for ExoMars 2018 Surface Platform (SP) science payload. The active neutron spectrometer of ADRON-EM instrument is under development in the Space Research Institute (IKI), Moscow. The dosimeter Liulin-ML of ADRON–EM is under development in the Space Research and Technology Institute-BAS (SRTI-BAS), Bulgaria (see Annex 1 - in Russian and http://exploration.esa.int/mars/56933-exomars-2018-surface-platform/). A participant in Liulin-ML is also the Institute of Biological and Medical Problems (IMBP-Moscow) that is responsible for the physical calibrations of the dosimeter and simulations of its response to different exposures. The PI of ADRON-EM is Igor Mitrofanov from IKI, Moscow, Russia.
The objective is to develop, manufacture, test and deliver (directly or trough ESA) to the PI of ADRON-EM the geometrical mass, thermal equivalent, engineering, qualification and flight models, the necessary hardware and software for testing and the necessary technical documentation of the dosimeter Liulin-ML of the ADRON-EM instrument for the ExoMars SP science payload. The dosimeter will be used for radiation environment monitoring onboard the Mars Surface Platform during ExoMars 2018 mission.
Compared to Objective 1 in the outline proposal - development, manufacture and testing of the qualification and flight models, the development and testing of the geometrical mass, thermal equivalent and engineering models are also added. This difference is due to the updated (during the elapsed time between the two proposals) current timeline for development, delivery and testing of the Russian led scientific payload for ExoMars SP (see the recent timeline in Annex 3a compared to the previous one in Annex 3 - in Russian). According Annex 3a the development, delivery and testing of the geometrical mass, thermal equivalent and engineering models continues to 31.10. 2016.
The Liulin-ML contains two dosimetric telescopes. Each pair of the telescopes consists of two Si PIN photodiodes and will provide absorbed dose rate, particle flux, energy deposition spectrum and linear energy transfer (LET) spectrum of primary and secondary charged particles and gamma rays aboard the SP. The combined data from Liulin-ML and the neutron detectors of ADRON-EM will be used to study the radiation conditions from all sources of ionizing radiation during the cruise phase and on the surface of Mars (functional diagram of Liulin-ML).
Data obtained will serve for verification and benchmarking of the radiation environment models and assessment of the radiation risk to the crewmembers of future exploratory flights.
The dosimeter Liulin-MO (see Annex 2) of the Fine Resolution Epithermal Neutron Detector (FREND) instrument for ExoMars TGO has been developed and manufactured in STPD-SRTI-BAS under contracts with IKI-Moscow. FREND including its dosimeter Liulin-MO has been flight qualified in IKI-Moscow, integrated and tested aboard the TGO s/c at TAS-Cannes and recently has gone final pre-launch testing aboard the TGO at Baikonur. The PI of FREND science payload is Igor Mitrofanov from IKI, Moscow, Russia.
The objective is to support the real time verification and analysis of the FREND’s dosimeter Liulin-MO data to assist with the ExoMars TGO mission planning activities.
The objective is to develop, test and provide to FREND PI and team the necessary Liulin-MO flight data products to be made available to ESA, Roscosmos and the international scientific community. The ownership of Liulin-MO data belongs to SRTI-BAS, IKI-Moscow and IMBP-Moscow. A mutual agreement between the three institutes has been signed that settles this ownership, as well as that all scientific publications based on Liulin-MO data will include the co-authors from SRTI-BAS, IKI-Moscow and IMBP-Moscow.
The objective is to survey, collect and store in unified format the existing Liulin type instruments data sets from ISS, BION, Photon and Chandrayan-1 satellites and to develop a web-based database that will serve users from all over the world. The available data of Liulin instruments is described in Annex 5. To prepare in a unified format the Liulin-MO ExoMars TGO data and to add them to the database. This will accelerate the analysis of the Liulin-MO data and will serve the ExoMars TGO team.
