Summary
Noise source
calibration:
Mingtang and Mal had a offline
discussion on the noise source calibration, they agree to use the wave guide
split version for prototype, Eugene will follow up to develop.
MMIC:
Bob has answered the TRW Sales
Questionnaires and sent back to TRW as well. Huei suggests If everything goes
right then we should ask them to start preparing the model for design ASAP.
Site:
Bob mentioned there are two places
he has seen, one is close to the camp of MLO, and the other is twice as far
as to the observatory, away from the building to the east, and both have crude
roads going to there. He will follow up to figure out the location with MLO
people.
7 arrays simulation:
Mike, Ravi and Bob are still working
on the simulation to the CMB polarization experiments with 7 arrays.
16 elements lag
correlator:
Jeff says all the design work is completed, and all parts should be coming
in a week. He will spend a couple of days there with Jeff to test the components
on next Friday and Saturday.
SiGe:
Warwick says it is proceeding in agree with the Germany company, and we need
a little bit work on the model to fit in the design system we use, and they
are interested in that work, so they can use for their test, and will give us
discount. We hope perhaps not have to pay some up front cost. Paul Robert starts
working on the model.
Prototype mount:
Philippe just starts making the first model, and so far the weight is too
much, he will keep on modifying the model and select lighter components. Fred
says we do want a mount to do what we all need to do, but clearly the simple
the better. Mike and Philippe will follow that direction to design the mount.
Philippe will send some information to Mike later today by fax.
Dishes:
Bob took the delivery of two small dishes, and they look good. He try to
arrange the mechanical measurement on those dishes sometime in next week. He
hopes to get a quotation and then place P.O. shortly.
