  1. IMPF International Microgravity Plasma Facility (IMPF) A Modular Multi-Purpose Research Facility for ISS T. Stuffler, J. Burfeindt, R. Seurig, R. Castegini Kayser Threde (Munich)J. Goree Univ. of Iowa

  2. Outline of this talk • IMPF Philosophy • IMPF Study Status • Phase A study • H/W pre-development phase • Time Schedule • Summary and Outlook

  3. IMPF Philosophy • Fully equipped laboratory for ISS plasma experiments • Facility operational for 10 years • Highly modular facility design • Experiment insert = 1 locker • Supporting hardware = 3 lockers • Flexible accommodation on ISS (political decision, barter object) • Insert exchange cycles • experiment e.g. 6 months • other inserts about 2-3 years

  4. 200 liter volume • Housed in 4 Mid-Deck Lockers Exchanged on a 6-month cycle Modular Construction • 1 Locker = 1 Module • Gas/Vacuum • Power Distribution • Data Processing • Experimental insert

  5. Accommodation • Undetermined Þ Requires Flexible Design to allow Accommodation Anywhere on ISS • Feasible Accommodations • US · Express Rack • ESA · European Drawer Rack • · Co-Accommodation with another instrument • (ICAPS = (Interactions in Cosmic and Atmospheric Particle Systems) • RSA · UDM

  6. Example: IMPF accommodated in Express Rack

  7. Current Design of the First Experimental Locker

  8. Gas Inlet/Outlet Automatic-Cleaning Vacuum Chamber Design

  9. Gas-Handling Locker

  10. Progress HTV Space Shuttle ATV Mission Scenario - Up-/Down-Loads • Up-load: Middeck Locker (MDL) or size & mass equivalent are compatible with Progress, ATV (TBR), HTV (TBR), and Space Shuttle • Down-load: only Space Shuttle is available for MDL type payload

  11. Project Phases • Phase A: Feasibility 8 months • Pre-Development: BB oriented feasibility (Special Tasks) 24 months • Phase B: Design (LLI procurement) 12 months • Phase C/D: Detailed design/Manufacture and tests 24 months • Delivery: L - 6 months • Phase E: Launch, commissioning /ISS implementation 10 years • Phase F: Disposal (of space waste) L + 10 years

  12. Phase C/D Flight Data Evaluation System Delivery IMPF - Time Line 2000 2001 2002 2003 2004 2005 2006 2007 2008 Pre- Development A B IMPF Phase A + B (IMPF 1,2,3) IMPF 1 RF Basic IMPF 2 DC Basic IMPF 3 RF Applied IMPF 4 RF / DC Basic PKE-Nefedov A B + C/D PKE 4 (tbc) Flight Events

  13. Development Approach for Experiment Insert • Pre-Development: selected component level development and evaluation • Breadboard: selected sub-system testing (interaction impact investigation)

  14. Development Approach for Experiment Insert (cont.) • Engineering Model (EM) Hardware: • Form, Fit, and Function of PFM • But lower grade components. • Used for engineering evaluation, test equipment development, procedures development • Proto-Flight Model (PFM) Hardware: • same hardware used for Qualification and Flight • Training Model • Software Reference Model

  15. Summary and Outlook • Dusty plasmas – an exploding research field, requires under µg-conditions • IMPF – International Microgravity Plasma Facility • advanced µg-platform for scientific community • exchangeable experiment and facility inserts Þ best science for a decade • Funding: • To date, DLR • ESA funding to be considered in Ministerial Meeting Nov. 14-15 (Edinburgh, Scotland) • Accommodation etc. undetermined, barter opportunities for future
