1. EUSO-BALLOON DESIGN REVIEW, 18.12.2012, CNES TOULOUSE Organization of the Instrument Team Andrea Santangelo IAAT, Eberhard-KarlsUniverität Tübingen • - Preamble • - Recommendations by the Steering Committee • - Organizationofthe EUSO-Balloonteam • - Remark on the International JEM-EUSO Team

2. Preamble This talk describes the key points of the EUSO Balloon instrument Organization. All details on the topic can be found in the “Organization Note of the EUSO-Balloon Instrument”EUSO-ON-INST-201-LALV2.6 The EUSO Balloon mission has been proposed by a consortium of three French Laboratoriesmembers of the JEM-EUSO international collaboration: The EUSO Balloon mission is fully supported by the JEM-EUSO collaboration Organization of the EUSO-Balloon Team

3. Preamble (2) CNES is in charge of the mission and leads and supervises the mission development. CNES supports the French contribution to the instrumentand the French participation to the development of the mission. The French Institutes of the consortium shall deliver the Instrumentfor the flights. The JEM-EUSO collaboration provides a complete and dedicated support to the definition and building of the subsystems, components and sub-assembly items of the Instrument. The development is under the management and responsibility of the French team in coordination with the JEM-EUSO management. Organization of the EUSO-Balloon Team

Mot, AIT/AIV manager • Identify Ground Support Equipment responsibilities (Action 1.2) See EUSO-AI-INST-251-LAL_V1.0 Organization of the EUSO-Balloon Team

5. PRR SteeringCommittee Report Recc. 3: Project Organization • To define an efficient and reactive management structure • - See new management scheme • To freeze requirements • See new ITS • Identify a set of minimal and sufficient documentation • Received by CNES and prepared. • Provide a realistic schedule, including AIT/AIV • See EUSO-AI-INST-251-LAL_V1.0 • See EUSO-DP.INST-207-LAL Organization of the EUSO-Balloon Team

7. Update: Project Manager (PM, Guillaume Prévôt) • The PM is responsible of the overall instrument technical performances, of the schedule, the costs and the coordination of all the activities • Organizes technical work, manages the interfaces (also with the Gondola) • Coordinates the technical work on the EUSO-Balloon within the JEM-EUSO collaboration in coordination with the JEM-EUSO management • Defines tasks, sets up schedules, checks the results, handles the delays in one word ensures the compliance to the schedule • Interfaces the CNES • Follows the various project procedures • Organizes regular meetings and milestone reviews • Organizes the preparation of the documentation needed in each development phase (short) title of presentation

8. Update: System Manager (SM, Sylvie Dagoret) • The SM is responsible for the development of the Instrument in compliance with the technical specifications: • Responsible for the instrument configuration and for the management of the external and internal interfaces • He reports and assists the PM and is assisted by the electrical, mechanical and thermal Architects and by the subsystem-managers • Interfaces the JEM-EUSO technical responsible persons (key role!!!) Organization of the EUSO-Balloon Team

9. Update: Architets • Gilles Roudil is the architect for the Mechanics. • G. Medina-Tancofor the thermal aspects. • The architects are responsible for the mechanical and thermal configurationof the Instrument • They are responsible for the preparation of the documentation relative to the internal and external thermal and mechanical interfaces. • Michel Dupieux is the electrical architect. • He is responsible for all electrical interfaces / interface documentsandcoordinates the activity among components responsible persons to ensure that connectors and cables are properly developed. • The Architects report to and support the SM. Organization of the EUSO-Balloon Team

10. Update: AIT/AIV Manager (AIT-M, B. Mot) • The AIT/AIV manager (AIT-M) is responsible for the definition, the development and the planningof the integration of the instrument and its sub-systems. • With the help of each sub-system manager, he defines the various tasks, sets up the schedule, checks the results, handles the delaysand tries to cope with the possible drifts in AIT tasks. • The AIT/AIV manager is assisted by AIT responsible persons for the various sub-systems: • AIT of PDM at LAL (SallehAhmad new person by LAL) • AIT of the DP at LAL (Sylvie Dagoret) • AIT of the mechanics at IRAP (Gilles Roudil) • the electric AIT at IRAP (Michel Dupieux) • AIT of the optics at IRAP (Baptiste Mot  Camille Catalano) Organization of the EUSO-Balloon Team

11. Update: Component Managers • There are four component managers: • Optics (TLE): T. Ebisuzaki • Photo Detector Module (PDM): M. Casolino • Data processing (DP): G. Osteria • Infrared Camera (IR-CAM): M. Rodriguez-Frias • They are responsible for the design, production, integration and testing of the components in compliance with the Instrument specifications and the external and internal interfaces. • Such a large international collaboration requires a clear distribution of responsibilities also at the sub-assembly level: Sub-assembly responsible persons have been identified. Organization of the EUSO-Balloon Team

12. A complex but clear organization Recc. 1 act. 1.4 Letters of Commitment have been prepared by all key contributors (and, by the way, most of the necessary items have been purchased and are available or are being manufactured)

13. Organization in France (1) In bold persons involved in management tasks at project level or at group-laboratory level

14. Organization in France (2)

15. Conclusions • The proposed structure can of course be updated following the suggestion of the committee… • The EUSO Balloon is fully included in the JEM-EUSO roadmap. • The EUSO consortium is fully committed to the EUSO Balloon activity: key persons of JEM-EUSO are taking concrete responsibilities. • Most important: the team has shown in the last months high motivation and commitment and that a strict schedule can be indeed met!

17. JEM-EUSO Collaboration • Japan, USA, Korea, Mexico, Russia • Europe: Bulgaria, France, Germany, Italy, Poland, Slovakia, Spain, Switzerland • 13 Countries, 80 Institutions, more than 290 researchers • RIKEN: Leading institution

18. EUSO Balloon • The EUSO Balloon mission is conceived as a pathfinder of the JEM-EUSO mission and of the challenging technique of observing UHE CR from space • It should perform: • End-to-end tests of the subsytems and components of the JEM-EUSO mission. • To prove the global detection chain, and improve the TRL • To improve our understanding the atmosphericand terrestrial UV background. • It might detect for the first time ever a cosmic shower from above.

19. Principal Investigator (PI, Peter Von Ballmoos) • The PI defines the scientific program and the specification of the mission in coordination with the JEM-EUSO management (PI P. Picozza, Deputy PI T. Ebisuzaki, Global Coordinator A. Santangelo) and the JEM-EUSO Instrument scientist Bertaina. • The PI, with the PM, ensures compliance between the system and mission specifications and the Instrument technical specifications and verifies that they are properly taken into account by the technical project team

20. CO-Principal Investigator (Co-PI, Andrea Santangelo) • In coordination with the PI defines the scientific program and the specification of the mission, and acts to ensure compliance between the system specifications and the instrument technical specifications and to ensure that the project is conducted in compliance with the objectives. • A central assignment of the Co-PI concerns the interface between balloon project and the JEM-EUSO collaboration.
