The nature of these memos and the reasons for their rejection are being provided only to their authors. The criteria for acceptance or rejection have not been announced, and inquiries have brought no response. If you are one of those whose memo has been rejected, please consider sharing your experience with the rest of us. In this way, perhaps we can all learn how to write an acceptable memo for ALMA.

Bacmann (ESO), S. Guilloteau (IRAM/ESO) 2003-05-24 Keywords: standing waves, subreflector, cone The amplitude of standing waves are calculated in various subreflector geometries (subreflector with absorber, subreflector with aperture to accommodate calibration loads). The ability of scattering cones to reduce the standing waves are compared for several types of cones (straight cone, inverse straight cone within the aperture, curved cone) and cone sizes. At 3 mm, the peak-to-peak ripple due to standing waves is around 0.7% for a subreflector with absorber, which can be reduced by a factor of 9 (~0.08%) by fitting a straight cone on the blockage zone. The ripple is on the other hand increased to 1.4% when the subreflector presents an aperture in the blockage zone. It can further be reduced to 0.8% by fitting an inverted cone inside of the aperture. Using a curved cone instead of a straight one can only moderately improve the standing wave level. We recommend implementing a straight cone covering somewhat more than the blockage zone. Further optimization of this parameter requires more elaborate software and should be carried out jointly with the Receiver and Antenna IPTs.

A. Ediss NRAO/Charlottesville 2003-05-29 For low-loss transmission of the LO in the ALMA Band 6 cartridges, overmoded waveguide may be used. In this paper, we report on the theoretical and measured losses of various sizes of waveguide in the frequency ranges 70-118 GHz, 220-330 GHz and 610-720 GHz.
