Dear ASAC:

I got the following email from Peter Stockman, STScI Project
Scientist for the JWST. He suggests that we collaborate with
them on a Joint Discussion at the IAU GA in Prague in 2006,
on a session on future instruments. THey are suggesting
JWST, ALMA, and Herschel.

Al and I agree that this is an excellent idea. We have not
discussed this further with Peter, awaiting your response.
A JD would not be too difficult to organize, and doing this
jointly with JWST and Herschel at the IAU GA would bring
together many astronomers from different regions
of the spectrum. It will take some energy, and the ASAC has
a busy year ahead. However, this seems to be a very
worthwhile project. Do you agree?

If we decide we are interested, then a proposal will have to
be prepared by January 1. The paperwork will not be too bad,
only a few pages in length (as I recall; if someone knows
differently, please correct me!), but what will have to be done
is come up with an organizing committee, and a plan for the
JD in concert with the JWST and Herschel people.

Action items:

==> Please let me know what you think of the idea, ASAP.

==> Please let me know if you might be interested in serving
on a subcommittee to organize this proposal (not necessarily
to organize the JD at this stage, just the proposal), also
ASAP.

++> If you have any ideas for the workshop, I can collect those
too. One thought that has occurred is that there might be
members of the ESAC or ANASAC who would be willing to help
organize the JD.

Dear Dr. Turner (Vice Chair ALMA Scientific Advisory Committee):

In the last week, we in the JWST project have pursued how the project  and
its science
could be presented at the 2006 IAU Symposium in Prague. There is a  small
chance that
facilities such as ALMA, Herschel, and JWST could speak as part of to  be
selected symposium --
they prefer to hear about real data or models! (imagine). However,  there
is a greater possibility
that we could create or participate in a Joint Discussion, perhaps 
associated with extragalactic
and star-formation divisions (in the case of ALMA in particular).

Has the ALMA science team considered presentations at the 2006
meeting? If yes, maybe you can
help us, if no and if you are interested, maybe we can help put
together a proposal from a number of important, international future 
facilities in the Sub-mm-IR regarding upcoming research capabilities.

  Unfortunately, the deadline for submitting a proposal to the IAU is
~ Jan. 1 so we would appreciate any
thoughts or information that you have.

Peter

Hi, Jean,

I think the Joint Discussion at the IAU sounds like a good idea, but I
don't have any time at the moment to help organize it or the ALMA 2006
meeting.

Dear Jean,

I think that the idea of a JD at the next IAU GA
involving JWST, Herschel and ALMA is a good one. 
The proposal could use part of the arguments already developed
for the recent DUSTY04 conference in Paris (which was a
success as you might have heard). Unfortunately, I will
not have much time now to help with the writing of a
proposal for the beginning of january. Sorry for this.

Best regards,

Pierre

Interesting idea.  as pierre says, it overlaps with DUSTY04 in paris last
month, which emphasized ALMA/Hershel.   My impression of dusty04
was that they got together a great group of people, but the meeting
never really made the scientific ties between ALMA and Hershel. 
ALMA is really a deep, high resolution device.  Hershel is a low
spatial resolution, confusion limited SED machine and dust spectrograph.
both are interesting, but the talks should be geared toward emphasizing
the complementarity.  JWST is more along the lines of ALMA -- deep
and high res, but in the near-IR.    simply put,  we have to avoid
having three separate conferences under one name.

i'd be willing to help out in the next few weeks, as needs be.

ps -- one strong recommendation would be NOT to put the GTO talks
at the very end of the meeting, as was done at dusty04.

ALMA Memo # 508
Low Phase Noise Laser Synthesizer with Simple Configuration Adopting Phase
Modulator and Fiber Bragg Gratings 
T. Yamamoto (NTT Network Innovation Laboratories), 
S. Kawanishi (NTT Network Innovation Laboratories), 
A. Ueda (National Astronomical Observatory of Japan), 
M. Ishiguro (National Astronomical Observatory of Japan) 
2004-12-01
Keywords: Laser Synthesizer, Phase Noise, Phase Modulator, Fiber Bragg
Grating 
We introduce a novel laser synthesizer with a simple configuration that
contains no phase lock loop. This laser synthesizer generates an optical
beat signal by modulating a CW light using a phase modulator and selecting
two line spectra from modulation sidebands using serially-connected fiber
Bragg gratings. With this configuration, the optical beat signal is obtained
from a single laser source by converting CW laser light into an optical beat
signal through a single optical path. This enables us to obtain a low phase
noise of the optical beat signal which is comparable to that of the RF
synthesizer that drives the phase modulator. In addition, polarization
stability is also obtained between the two line spectra. The complete
frequency range of the optical beat signals required in ALMA can be covered
using this laser synthesizer.
