Abstract : The over-all layout of the film scanner was established and a substantial amount of detailed design work carried out. The equipment will comprise two self-contained, transportable units for which the only necessary external supply will be electrical power. An electron gun of improved design was built and tested. It is now possible to achieve a resolution of 100 line pairs per millimeter across a flat test target 4-1/2 inches wide. The use of a flat film carriage (in place of the previous design which had curved guides) will simplify considerably the design of the film transport. In the area of electronics the main timing unit, deflection waveform generators and amplifiers, and correction waveform synthesizers and amplifiers were designed and tested in breadboard state. Construction has started on the final units. The main features of the vacuum system are now known. It will be possible to switch from manual to fully automatic operation, and in either mode, the vacuum valves (which are pneumatic) will be actuated by electrical signals. Rough vacuum, compressed air and cooling fluid will be supplied from built-in units.
