Facilities 13 juin MAVEN-SWEA instrument peer review / CESR  Class 1000 clean room for MCPs and detector assembly (CESR)  Class clean room for electronics and mechanics assemblies (available early may 2010) (CESR)  Small clean room for electronics gluing and coating (CESR)  Vacuum chamber and particles beam in class clean room (see A. Fedorov presentation)  Thermal chambers (-60°C to +120°C) – CESR  Class clean rooms available in sub contractors premices (Comat, Microtec)  EMC test facility: in Microtec (sub contractor)

Main sub contractors 13 juin MAVEN-SWEA instrument peer review / CESR  COMAT AerospaceMech. Fabrication & integrationsame as for STEREO (Toulouse)Tools for assemblysame staff as for STEREO Assembly docs (procedures, as_built, control reports, QA,…)  CORIMA (Loriol-FR)Entrance grids fab & gold treatment same as for STEREO  Collini & Fluhmann(Swi)Black copper same as for STEREO  SWIPELEC (Bordeaux-FR)MCP grids same as for STEREO  HIREX (Toulouse)EEE parts screening same as for STEREO EEE parts procurement(Tecnologica group)  CIRETEC (Toulouse)PCB fabricationCNES/ ESA qualified  MICROTEC (Toulouse) Parts & PCB welding, same as for STEREO Harnesses  Mecano-ID (Toulouse)Environmental tests

Reference documents 13 juin MAVEN-SWEA instrument peer review / CESR  STEREO SWEA Performance Assurance Plan  STEREO SWEA UCB to CESR Interface Control Document  MAVEN PFP performance requirement  MAVEN PFDPU to instruments ICD  MAVEN – UCB Mission Assurance Implementation Plan (MAIP)  Maven harness specifications  Maven grounding specifications  Maven latchup LET criteria (tech. Note - UCB)

AIT documentation 13 juin MAVEN-SWEA instrument peer review / CESR As built lists (materials, EEE parts, processes) As built assembling procedures Environmental testing reports (if any) Log book Non conformity reports with appropriates corrective actions Photographic documentation of FM hardware Analysis reports (mechanical, electrical, …) Tests reports

Cleanliness and contamination issues (1) 13 juin MAVEN-SWEA instrument peer review / CESR  Microchannel plate cleanliness requirements (same as for Stereo) Sensitivity to humidity, dust & hydrocarbons Discharge created by 100 microns particles can damage MCPs Outgassing near MCP to be avoided Special procedure to clean MCPs and restore properties  Permanent purging system installed on Swea with dry nitrogen at 5 liters/ hour Plastic hermetic container filled with dry nitrogen acceptable for transportation (couple of hours) few hours without purge flow is possble in clean room environment MCPs or sensor equiped with MCPs is stored in vacuum at CESR  Hermetic red tag cover on Swea analyser can be removed only in a class 1000 clean room and has to be kept on Swea analyser during I&T

Cleanliness and contamination issues (2) 13 juin MAVEN-SWEA instrument peer review / CESR  All mechanical parts are cleaned with alcohol  All assembled parts are stored in vacuum chamber in Cesr clean room  Integration in clean rooms Class 1000 CESR clean room for MCPs and analyser Class CESR clean room for electronic boards In subcontractors clean rooms (Comat or Microtec)  Unit bakeout for outgassing before first calibration tests  SWEA analyser stored in vacuum before calibration or before delivery to UCB  Bakeout of full Swea instrument at UCB

SWEA – MAVEN Protoflight AIT Flow Chart 13 juin MAVEN-SWEA instrument peer review / CESR Note: Stereo-SWEA Engineering model analyser will be re-furbished according to Stereo to Maven changes and modifications indications will be given to SSL (date TBD) in parallel with AIT activities

AIT Schedule ( ) 13 juin MAVEN-SWEA instrument peer review / CESR Delivery date to UCB TBD (mid 2011) Uncertainties due to open issues (Stereo to Maven changes)

AIT: procurements & work in progress 13 juin MAVEN-SWEA instrument peer review / CESR  Most of assembly tools available at CESR or in Comat  Stereo-SWEA engineering model available for « Maven modifications »  Flight MCPs ordered (delivered late february 2010)  Flight PCBs & MCP supports to be delivered March 2010  Contract signed with Comat (mech. Subcontractor) – waiting for changes issues decisions.  Charge amplifiers A111F ordered to Amptek with GSFC screening (delivery 02/15)  Some EEE parts ordered, most of deliveries expected in May 2010  Stereo parts re-screening: quotation received

Next activities 13 juin MAVEN-SWEA instrument peer review / CESR o Update CESR / UCB documents (ICD, QA) o Update product tree and setup doc server o Update product tree (extrapolated from Stereo-Swea) and setup documentation server o Update EEE parts list, material list o Fix most of Stereo to Maven changes issues with UCB o Order all missing flight parts o Order high voltage optocouplers fabrication. o Order pinpullers o Mechanical parts fabrication o
