2. Oct 17, 2001SALT PFIS Preliminary Design Review Fabrication and Test Plan 2 Facilities UW Dept. of Astronomy resources Machinist 3 Electronics Technicians,1 with spaceflight qualifications Well-equipped machine shop Class 1K clean room with 2 class 10 flow tents and 1 laminar flow bench Thermal chamber covers all SALT operating and survival ranges in temperature - sized for actuators and mechanisms, not structure Available from UW Physics Dept 6-person machine shop, accepts any size job Available from Rutgers University Large machine shop with invar welding

3. Oct 17, 2001SALT PFIS Preliminary Design Review Fabrication and Test Plan 3 Fabrication and Test Strategy Mitigate large number of mechanisms with “pipeline” –Standard bench setups for acceptance testing of actuators –Test mechanisms as they come out of fabrication –Rapidly prototype software modules, use early experience to feed back into design –High degree of commonality allows a few standard modules to be reused over and over –Simulate missing components to allow high-level controls to be prototyped and used

4. Oct 17, 2001SALT PFIS Preliminary Design Review Fabrication and Test Plan 4 Test Procedures Testing will be required throughout program –Bench-level testing of components –Assembly-level testing –Instrument-level testing –Pre-ship functional –Acceptance testing in Cape Town –Complete functional testing in Sutherland Procedures will be developed incrementally Procedures will embody experience gained during fabrication

5. Oct 17, 2001SALT PFIS Preliminary Design Review Fabrication and Test Plan 5 Documentation Documentation will include –User manual –Troubleshooting guide –Software source code –Test procedure scripts –Mechanical drawings –Wiring diagrams and lists –Vendor’s material for purchased items

6. Oct 17, 2001SALT PFIS Preliminary Design Review Fabrication and Test Plan 6 Interfaces: Detector & Telescope Detector and telescope services will be provided according to an interface using LabVIEW network protocols Very important: early design, rapid prototyping, nail down the ICDs. Simulation mode is critical - support protocols before actually providing services Test software modes long before integration of hardware –Frequent incremental exchanges of software & simulators –Intercontinental testing of network modules
