Dr. Timothy Coffey, the NRL Director of Research, will welcome the Solar-B Team. 1.Status Opening remarks JLC Conclusion of the US selection process - what of the NRL proposal is still proposed? GAD Kick-off meeting at ISAS, March 99 HH 2.Science Review of major science goals JLC/GAD/HH The Four Wavebands: Science & Countrates KPD/LKHM/All - referring to : line lists with countrates and EIS studies (UK/J) as detailed in "EIS science notes" http://www.mssl.ucl.ac.uk/solar-b/docs/sci/notes4.html and http://www.mssl.ucl.ac.uk/www_solar/solarb/eis_wave.html SERTS observations of HeII JD/ Value of HeII as a transition region line (comments about CDS experience would be welcome) RAH? Multilayers at 400 A JFS What are the prospects for observations in this region? 3.Instrument (telescope) configuration The NRL Cassegrain Telescope/Spectrometer CK its properties, advantages, and problems) Some questions which may arise include . What are the mechanisms and their nature? (e.g. disturbing torques) NRL Is there a slit exchange mechanism or a slit/slot? " Are there focus adjustment mechanisms? " What are the positional tolerances of the components? " Is there, or is there a need for, an optical metering subsystem? " What does the focal surface of the grating look like? " What are the assumed detector properties (pixel size and format)? " (Available EEV CCD formats MSSL) The Baseline (aka trendy) instrument HH? Other instrumental drivers - Filter (Al) transmission curves JFS - Calculation of Multilayer reflectances. Performance of real-world ML's JFS/JD - Grating configuration (groove reflectivity vs wavelength & order, multiple waveband) JFS 4.Selection of EIS Science and Instrumentation Discussion, with the aim of reaching a decision on the wavebands and telescope type, or at least develop a plan for reaching such a decision by the March meeting in Japan. All Chair - JLC Day 2 - Wednesday 27th January, 1999 5.Technical Topics 5.1 Spacecraft resources Mass, envelope, power, resonances, telemetry, thermal properties, pointing HH 5.2 Structure vacuum vessel or purged ? SM? use of clamshell-protected entrance filter materials - tolerances - outgassing Summary of tradeoffs 5.3.Detectors CCD detector performance MW Progress with breadboard hardware 5.4Electronics System block diagram MW Operating concepts, data flow, processing cycle /HH Interface philosophy MDP interfaces 5.5.General Topics Alignment, Calibration -> Performance Verification PlanAll Methods of achieving instrument performance - including modelling, subsystem testing and calibration activities Cleanliness -> Contamination Control Plan - seek LASCO & CDS experience MW/CK? Subsystem requirements that flow from contamination control methods 6.Technology Management 6.1.Management Plans Technical coordination in/across institutes MW/All Common management plan? Common development teams (SDT / IPDT) ? Communications: - Points of contact, - exchange of documents etc. 6.2.Technical Coordination Need to discuss/agree on the following: information to be determined during Phase A about each system interface and approximate times (i.e. agree on the format of the interface documents, including the spacecraft interface control document). System block diagram and interface list, including spacecraft interfaces 6.3.Events in the Near-future Kick-off meeting in Japan. Phase A : Scope and duration Timing, scope and attendance of Future reviews - Requirements Review, Preliminary Design Review 7.Resolution of outstanding issues 7.1 Assignment of hardware responsibilities 7.2.Review of actions etc 7.3.Discussion of schedule 8.Conclusion 8.1.Any other business 8.2.Date of next meeting
