Conclusionssome general thoughts
NL strong in submm because of very strong synergy between science and technology Perfect up to Herschel and ALMA, but future less obvious Need to keep this synergy if we want to be successful in the future
We have access to prime submm facilities through APEX and ALMA => need very strong science case to ask for significantly more money in this wavelength range CCAT: Extragalactic targets for ALMA Synergy science and technology?
Fantastic new technology, but where will it be applied for science? Any new facility will likely not materialize until 2015, perhaps 2020 Far-infrared wavelength range poorly explored, especially
spectroscopically at medium/high resolution Problem: how unique is science case compared with ALMA and JWST?
Mission operations timeline
Lack of high spectral resolution!
Lack of shortwavelengths!
SPICA? SAFIR?
SpectralResolution
Spectral resolution vs wavelengths
Future facilitiesContinuum Line
- Note jump in sensitivity of SPICA compared with other facilities in 30-300 micron range- Figure needs to include Mmtron
ALMA
Clearly highest scientific priority Needs to be supported scientifically and
technologically to reap full benefit
But…. Need complementary wide-field/multi-object
facility, especially for extragalactic work Heavily oversubscribed No hands-on training
APEX
Constructed and working! Good platform for 400-900 GHz range Still much to explore and exploit, at least for
next 5 years Even factor of 2 will help, if it could be realized
on short term Good platform to train students But…. APEX limited lifetime (up to 2013?)
CCAT
Interesting option, mostly from extragalactic experience
Expertise available for heterodyne arrays Scientific interest mostly in continuum/low
resolution for extragalactic Can money be found? How much? Need
realistic estimate? Who would lead from NL side?
SOFIA
Not much scientific interest, niche science, poor sensitivity
Platform for high frequency technology Not worth raising Dutch money for, but
perhaps involvement in detectors (if paid elsewhere?)
SPICA
Tremendous raw sensitivity!! Spectral resolution limited, even factor 2
would help (R=1500 => 3000) Most likely space mission to go? Need strong science team involvement to
drive instrument design FTS vs grating
Mmtron
Potentially powerful, but still poorly defined in terms of wavelength coverage and instrument suite
Comparison with SPICA has to be done quantitatively
How realistic that it will end up as currently being planned? Too ambitious?
FIRI
Long term Need to keep pushing development of
technology
Actions
Wolfgang: NOVA 3 instrumentation part: check whether NWO-M proposal is needed for CHAMP+ upgrade
CCAT/APEX WG: science trade-off: is it strong enough for structural involvement in CCAT? If so, NWO-G next september? Need decision in March 2009
SPICA/Mmtron WG: science trade-offs and definition Mmtron science capabilities. Needed by January 2009
