The dummy mirror will be installed during the test and the test will include a test firing of the filaments. Karl Harrar is continuing the design of the filament supplies. There seem to be no show- stoppers. The rms error, determined by optical testing with the test plate, is 28 nm. Non-axisymmetric errors are small.
Work is directed primarily at radial zones.
Polishing has not yet begun, but the tools are all nearly assembled. The Italian vacation schedule is slowing things somewhat. The MMTO needs to contract for the fabrication shortly. Following a review of the design, fabrication will take about 3 months. All items for the cell have been fabricated.
