13 Swedish Institute of Space Physics Objectives Space Campus, Kiruna The Swedish Institute of Space Physics (IRF) conducts research and education in space physics, space technology and atmospheric physics. Basic research in space plasma physics (e.g. magnetospheric- and ionospheric physics), space technology and atmospheric physics. Applied research in signal analysis, sensor technology and satellite technology.

14 Swedish Institute of Space Physics The Swedish Institute of Space Physics (IRF) conducts education and both experimental and theoretical research in space physics, atmospheric physics and space technology. Measurements are made with the help of satellites, balloons and ground-based equipment. IRF was established in 1957 by the Swedish Academy of Sciences as Kiruna Geophysical Observatory. IRF has been a state-owned research institute since IRF has offices in: Kiruna (head office) Umeå (in the Technology Building, Umeå University) Uppsala (at Ångström Laboratory) Lund (at IDEON Science & Technology Park) And the unmanned Lycksele Ionospheric Observatory

56 Spacecraft-Environment Interactions 5 points = 7.5 ECTS = 5 full weeks = 4 points theory + 1 point computer practical Environments: Neutral Plasma Radiation Particulates and associated effects on s/c Course literature: Tribble or alt. Hastings & Garrett, compendium, and lecture notes Teachers: Johnny Ejemalm and guest lecturers

57 Practical: Space Environment Laboratory Work with SPENVIS: Radiation Environment and Effects (original idea: Laila Andersson) students are given Laboratory Instruction notes and Brief Guidelines notes on SPENVIS and are asked to write a short report (15-20 pages) of their results formulating themselves as if they where real technicians in the space industry asked to investigate a proposed project one or two students in a group results are not graded but may influence exam results

58 Objectives: 1 Define the mission! (Either default from SPENVIS, actual mission or own invented mission.) 2 Illustrate the orbit! 3 Describe out from theoretical knowledge the significance of the different space environments the s/c is supposed to meet during different phases of the orbit! Also describe expected effects on the s/c during different phases of the orbit! Also give characteristic values of physical parameters! Where is the radiation environment strongest? Which are the critical phases of the mission? Describe the composition of particles in the radiation flux! 4 Compute the different environmental fluxes! Compare and verify the critical phases!

59 5 How thick must the cover glass for solar panels be (in order to not exceed 1 MeV electron equivalent fluence of 1015 electrons/cm2 during the mission)? How long time will the memory device function (if it can take 1.0 Mrad and is mounted in the front face of the s/c in a shielded box)? How thick must the shielding be in order for the memory unit to function during the whole mission? 6 Determine the LET spectra, i.e. the particle flux F(LET) for a shielding thickness of 1 g/cm2! 7 Determine the cross section for 4 certain electronic chips by fitting a Weibull function to data with help of MATLAB! For one of the chips the 4 parameters of the Weibull function are not given. The students has to determine these parameters out from given (fake) experimental data.

60 8 9 Compute the SEU rate for each electronic device in the worst case of space environment with help of MATLAB! When is the SEU rate highest during the mission? Which electronic device is recommended? Conclusions: Is there a danger for the s/c or its equipment? What are your recommendations? Is the performance degradation in accordance with mission duration and requirements

61 Experience of using SPENVIS as a pedagogical tool: Encourage independent seeking of information Visualization fascilitates understanding, especially of 3-dim objects Students motivated by usage of sharp program used by space engineering community Suitable for students with different backgrounds Speeds up learning

62 Improvements? Space environment (neutral, plasma, radiation, particulates) is 3dim with many non-symmetrical properties (magnetic field, plasma disk bulge, polar horns, SAA, radiation belts, grav. attraction and shielding by Earth of MM, OD distribution.). Takes a lot of time to explain! It would be nice if the space environment could be visualized, not only along a s/c track, but as a whole (in Earth vicinity)! Problem with 3-dim visualazation: How to keep look-thruu properties?

63 Why not displaying properties color coded (like e.g. omnidirectional flux of e.g. electrons with energies > pre-defined value) along a fairly sparse 3-dim coordinate grid? Colors has to be easy to understand! Full spectrum inappropriate. Perhaps red to blue? Coordinate grid could be e.g. spherical polar or cartesian. Grid need not be equidistant e.g. in radial direction. Zooming properties would be desireable. Perhaps by clicking on a grid crossing point. Different viewing angles should be possible.

64 Perhaps grid lines as option could be built up with small symbols (squares, triangles, circles, ), that stands for some other property (e.g. quality of data in database: in situ measurements, interpolated, ).

65 Is this possible?
