2. Space Research Institute BMSW on the future mission: Strannik; Luna-Glob ; Interheliozond; Venera-D  fast plasma and energetic particle measurements;  3D electric and magnetic field measurements,  Single spacecraft  Outer magnetosphere orbit (apogee 25-30 Re) The tasks:  Plasma turbulence up to electron scales  Thin boundaries and transient processes The mission is open for collaboration! Contact person: Anatoli Petrukovich apetruko@iki.rssi.ru Strannik “Piligrim” is the fast-track cheap mission relying on heritage of previous projects (combination of PLASMA-F and Resonance instruments). Approved by Russian Space Agency, currently in payload definition phase. Strannik “Piligrim” - the nearest mission (launch ~2016):

3. Experiment “Plasma-F” on spacecraft “Spectr-R”  Turbulence in solar wind and magnetosheath  Fine structure of energetic particle acceleration Time resolution up to 32 Hz 2011 Space Research Institute BMSW – solar wind flow parameters (faraday cups) Russia, Czech republic, Kyrgyzstan, China MEP – energetic particles(Si-detectors 20-1000 keV) Slovakia, Russia, Greece SSNI-2 – onboard data handling (100 GB) launched July 2011

4. BMSW instrument on SPECTR-R (current mission) Measurements of: - Solar wind ion flux value and direction (time resolution 30 ms) -Plasma solar wind parameters in swept mode (most of the time) : proton density, bulk speed, temperature, Alfa particles/proton ratio ( resolution 3 s) -Plasma solar wind parameters in adaptive mode (separate time intervals): proton density, bulk speed and temperature (resolution 30 ms) BMSW instrument. Fast monitor of solar wind plasma parameters. Objectives of the study: -Turbulence in solar wind and magnetosheath on ion dissipation scale -Investigation of small scale discontinuities in the solar wind and magnetosheath -Investigation of fine structures of fronts of discontinuities (for example shock) Typical energetic spectrum distribution (BMSW, SPECTR-R) Current on collector Voltage on control grid Vp Tp Alfa particles adaptive mode

5. The main principe of the BMSW instrument and features of the «new» BMSW C2, C4 – grounding grid; C3 – control grid; C1 – suppressor grid Collector Sensor – Faraday capidea of the two part collectors laboratory sample of the new sensor DP-10-34.  All the sensors are identical and directed along the axis of the device oriented to the sun.  Sensors have collectors cut into two parts (one sensor can measure the direction of the flux in one plane). It provides flexibility, reservation and possibility to intercalibrate sensors in flight.  Sensors are united in pairs (one pair - for measuring ion flux vector (magnitude and two angles with time resolution 30 ms), the second - for sweeping mode (measurements of full energetic spectrum, and Np, Vp, Tp, Na/Np with time resolution 1.5 s), the third - for adaptive mode (measurements of Np, Vp, Tp with the highest time resolution 30 ms)).  Sensors will have wider angle diagrams ± 60 .  new BMSW will consist of two types of blocks – main and additional (to have the possibility to measure the particle from the direction not to the Sun ).  new BMSW will be almost identical for all projects.
