Leland HillAMS-02 Phase II Safety Review 1 PHASE II FLIGHT SAFETY REVIEW
2
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.
4
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.
6
Leland HillAMS-02 Phase II Safety Review 6 Participants AMS-02 Notations on primary focus are the best estimate that can be anticipated. We need to be prepared to discuss any aspect of the hardware Subsystem Representation (with leading engineers) TRD – S. Schael, K. Luebelsmeyer Materials, Construction, High Voltages, Pressure System will be primary safety focus. TRD Gas System – T. Siedenburg, U. Becker, (K. Luebelsmeyer) Pressure systems, heaters and Radioactive Materials will be primary safety focus. TOF – F. Palmonari, G. Laurenti, G. Castellini PMTs, High Voltages and Construction will be primary focus. ACC – T. Kirn PMTs, High Voltage, and Construction will be primary focus.
7
Leland HillAMS-02 Phase II Safety Review 7 Participants AMS-02 Tracker – R. Battiston, G. Ambrosi, E. Perrin Construction, Venting will be primary focus. Tracker Alignment System – W. Wallraff Laser Energy Analysis and Laser Containment will be primary focus Tracker Thermal Control System – J. Van Es, Z. He Pressure Systems and Heaters will be primary safety focus RICH – G. Laurenti, J. Berdugo, C. Diaz Materials, Fragile Materials, PMTs, High Voltages will be primary safety focus. ECAL – F. Cervelli, M. Incagli, F. Cadoux Construction, PMTs, High Voltages will be primary focus.
8
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

12
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.
13
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.
14
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
15
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.
16
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.
17
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
