Leland HillAMS-02 Phase II Safety Review 1 PHASE II FLIGHT SAFETY REVIEW

Leland HillAMS-02 Phase II Safety Review 2 Pertinent Facts  Phase II Flight Safety Review will be held during the week of May 21-25, 2007  Phase II will be held at a facility near Johnson Space Center  Facility will be offsite, but will still require a level of registration, not as difficult as NASA badging.  Letter will be sent with registration requirements in advance of meeting once building and current requirements understood.

Leland HillAMS-02 Phase II Safety Review 3 Phase II Safety Review  Meeting is conducted by the Payload Safety Review Panel and chaired by their Chairman.  The purpose of the meeting is to audit our compliance with relevant requirements.  We will present design and operations to the PSRP.  We will present hazard reports and support technical information  PSRP will interrupt with questions frequently.

Leland HillAMS-02 Phase II Safety Review 4 Phase II Safety Review  Focus will be on safety related systems and not the science of the mission.  PSRP will be interested in hearing about science, but that is not their focus.  We must be prepared to talk about the hazardous systems that we’ve identified in the Phase II safety data package.  Mission success is often discussed but in context of the maintenance that is required to attain it.  We are not using maintenance in their context with the AMS-02.

Leland HillAMS-02 Phase II Safety Review 5 Participants  PSRP will have representation from many disciplines and organizations  Shuttle Program  ISS Program  Engineering  Operations  Astronaut Office  Life Sciences  Shuttle Integration  ISS Integration  Safety Mission Assurance Office  Others as they desire.

Leland HillAMS-02 Phase II Safety Review 6 Participants  AMS-02  Notations on primary focus are the best estimate that can be anticipated.

Cervelli, M. Incagli, F. Cadoux  Construction, PMTs, High Voltages will be primary focus.

Leland HillAMS-02 Phase II Safety Review 8 Participants  AMS-02  Electronics – M Capell, A. Lebedev, S. Alia  Primary safety focus will be on Power Distribution, Wire Sizing and Fusing and Control  CAB – G. Munoz, H. Cuesta  Magnet charge/Discharge/Quench control will be primary safety topics  UPS – T. Urban  Batteries and the safety use of them will be a significant topic at the safety review  Thermal – J. Burger, M. Molina  Construction, Pressure Systems and Heaters will be a primary safety focus  Passive Thermal Control (blankets, etc.) – J. Cornwell, C. Clark  Materials, Construction, Attachment will be primary safety focus

Leland HillAMS-02 Phase II Safety Review 9 Participants  AMS-02  Cryomagnet – S. Harrison, R. Stafford- Allen, M. Gallilee  Magnet/Magnetic Fields  Superfluid Helium Tank  Superfluid Helium Plumbing  Power Management of Magnet  Structure of Magnet  Warm Helium Gas Supply  Vacuum Case – P. Mott  Straps – C. Tutt

Leland HillAMS-02 Phase II Safety Review 10 Participants  AMS-02  Star Tracker – P. Trampus  Cryocooler – K. Banks  Integration – R. Becker, C. Gargiulo  USS-02 – K. Nguyen  PAS – J. Kastelic  DDRS-02 – P. Dennett  Materials – C. Chang  Operations – T. Urban, P. Nemeth  EVA Interfaces – T. Urban, D. Nguyen  SAFETY – L. Hill

Leland HillAMS-02 Phase II Safety Review 11 Participants  And most assuredly we need:  Professor S. C. C. Ting  Steve Porter  Trent Martin

Leland HillAMS-02 Phase II Safety Review 12 Agenda and Presentation  An Agenda will be prepared in advance to organize our presentations.  Will evolve as we move forward, draft agenda is in work.  Two days are anticipated for technical presentations, and three days for hazard reports and discussion.  Rehearsal at CERN TIM in April  Will send out presentation outline by end of January  Presentations will have to focus on design, construction and function to educate the PSRP on the hardware and operations.  Presentations will be coordinated for content for content and timing prior to meeting.

Leland HillAMS-02 Phase II Safety Review 13 Presentations  Keep presentations direct and with graphics intended for discussing the topic and up to date  Assume PSRP knows nothing about the payload and system, as if they have not read the safety data package.  The PSRP Reviews well in excess of 200 payloads in a year, they will always try and draw corollaries between what we say and what they’ve heard before.  The questions you may hear may seem out of context and silly, but there is likely a lot of history as to why it was asked, it probably means we didn’t explain something as fully as we thought. We answer and move on.

Leland HillAMS-02 Phase II Safety Review 14 Presentations and Backup  We need to balance the depth of data in the presentation with additional data that we can carry with us and have ready to display on need.  We will wait for the need and not volunteer extra data without call, that can become a trap too of going down the wrong road on topics.  Even with five days, we have a lot of information to get through

Leland HillAMS-02 Phase II Safety Review 15 Success Notes  Presentations should be clear and easily read.  Cute backgrounds and animations make fine selling points, but we need to focus on getting the information clear and transferred easily.  Small type and colors with low visibility/contrast should be avoided.  Safety Panel has acronyms from two major program and dozens of smaller projects in their heads, we need to keep our acronyms and abbreviations well defined.  Mind your borders and keep relevant data back from them, projectors can’t always be trusted to be aligned.

Leland HillAMS-02 Phase II Safety Review 16 Success Notes  Our Data needs to be up to date.  Late changes should be presented clearly, but should also be coordinated with Safety Engineer in advance.  Closed verifications are good things to bring to add to for this meeting.  Discussions should be in whispers before we take it before the PSRP  Better yet, take them outside of the meeting room, the microphone system picks up whispers some of the rooms.  There will likely be PSRP members that are participating by telecon, we need to have presentations ready in advance so that they have a copy.

Leland HillAMS-02 Phase II Safety Review 17 Expectations of the Meeting  Expected to happen  Plenty of discussion  Misunderstanding  Revisions to our paper  Signed hazard reports  Action items.  Not expected or at least not hoped for  Design changes  Additional testing and Analysis  Don’t make the presenter look bad by contradicting them
