| Description | Telling Dr Mann about a 'new and favourable development' that has been reported regarding the Arecibo [Ionospheric Observatory] feed situation. Work carried out at Autonetics and UCLA 'demonstrates that a section which is representative of about the middle of the Arecibo feed radiates completely correctly, both in uniformity and in the polarization components'. He and Professor Rumsey think it likely that this is a 'very good solution to our problem'. Says that he will let Dr Mann know as soon as he has made a firmer decision. Says that 'It looks very likely, however, that we will ask ... for a continuation of the contract with Autonetics on the basis that the difficulty noted by them which caused the interruption has now been removed'. |
