  1. Brazilian Tunable Filter Imager(BTFI)Preliminary Design Review (PDR)‏ Management Summary (Keith Taylor) Version 1.0 USP-IAG Universidade de São Paulo 18-19th June 2008

  2. Compliance Matrix • BTFI almost completely compliant with • Science requirements • Interface requirements • Compliance Matrix incorporated into Requirements Document • as updated since CoDR • So what are the exceptions?

  3. Non- (or partial) compliance • Each filter wheel contains a maximum of 4 filters • Filter wheel is under remote operation (unplanned at PDR) • FPs cannot be removed from instrument w’out dismantling • No angular adjustment of FPs • Full-up weight still uncertain but is of decreasing concern • New iBTF gratings will be aligned in SOAR telescope optics lab • Non-exitant, but strong lobby from Tighe (and ourselves) • Director says “$$s available” • Optics procurement • Unmounted or in barrels (tbc)? – await final optics bids • Camera shutter – woops; forgot about this! • CryoTiger not LN2 • Commissioning to Hand-over support logistics (tbd)

  4. Risk Register • Available on Wiki as an Excel Spread-sheet • Organised, as follows

  5. My favourite risks • Operation & Maintenance • Detector controller • CCCP-v1 result encouraging • Reliability & Maintainability uncertain • Etalon controller • Absolute capacitance servo - Gravity effects? • SAM interface • SAM availability – what is role of BTFI in SL-mode? • Optics • FP performance – unproven technology • Pipe-line Data Reduction • Robust but user-friendly algorithmics • Scientific impact requires avoidance of off-line DR, if at all possible

  6. Optics/iBTF/FPs

  7. Structure & Mechanics

  8. Detector System

  9. Software, IntegrationTest & Commissioning

  10. Conclusions(from PM perspective) • Capable, well-motivated, team • Geographic dispersion appears not to be a problem • Opportunities to involve post-docs from USP and elsewhere • Adequate budget with opportunities to bid for enhancements • More gratings, filters, contingencies etc • Technology (iBTF, EMCCD, SESO, 2-channel) • Excitingly, new but tractable • Not everything has to work at 1st light • Opto-mechanical design - compliant with science goals • Credit to Damien & Rene • Electronics & Software - under control • Positive interaction with SOAR staff • SAM availability - biggest concern from a science impact perspective • In the interim: is it possible to give BTFI a 6arcmin. seeing-limited FoV?
