So I think what we really need now regarding GW is to know if any
hardware funding could be included.

Instrumentation -wise:

1. Virgo upgrade funding should come from submitted NWO-Groot;
2. LISA (joint SRON/Nikhef/TNO) ambition is different. The idea is to
    submit NWO-Groot (SRON with Nikhef as participant) in 2020. 
    I think Zwaartekracht could be an option here. In particular if
    crucial people like Ralph and Stan would agree on matching an
    eventual Zwaartekracht proposal with some investment funding from
    NOVA (Ralph) and Nikhef (Stan) ... If so, my understanding would
    be that NOVA  in particular would address CTA needs. If so, Nikhef
    could consider to address LISA needs in as far as it concerns Nikhef
    instrumentation work: novel quadrant diodes (new materials, low noise,
    Niels van  Bakel and (Dutch) industry). Funding up to 500 kEuro would
    be extremely desirable and put our Dutch consortium within LISA better
    on the map. (Other contribution is between SRON and TNO). Science wise, 
    I think case for LISA is already well documented (low frequency GW).
3. not direct science, but preparing it: in view of ET there is a strong interest
    in an R&D facility. a 20 meter cryogenic laser interferometer aimed initially
    at large mirrors of new materials to be operated at 120 or even 20 kelvin
    (magic temperatures for silicon based mirrors: zero CTE).
    Overall funding over first 5-7 years estimated between  10-15 MEuro capital
    investment  (depends who you ask). Channels to draw from:
    - Limburg Province
    - EZ (INTERREG, EMR, .... all things new to us)
    - Belgium and German  institutes/government
    - our institutes and government
    Also here a contribution from Zwaartekracht would be very welcome. Order
    MEuro ... 1?

More science wise, but to be considered to include in our proposal:
1. CMB efforts. Leiden voiced an interest to participate by exploring
          the B-modes imprint on the CMB (the  BICEP2 'screw-up'). I guess we
          need to discuss whether or not to include this in our proposal. I do
          not see hardware contribution ... even  though  I still think a Nikhef
          contribution to e.g. CUBIC would have been nice but QUBIC is progressing
          (too) slow and we at Nikhef (Dorothea notably) did our best to join,
          but failed to date. In Europe three workshops were organized (Florence,
          APPEC initiative). Very stimulating, but sofar real progress frustrating.
          Consult Dorothea once again? It would connect people from Leiden ...
 2.  PTA/Lofar: could be connected for very low frequency GW. Pulls in 
           Joeri van Leeuwen from ASTRON/UvA and  perhaps Jason Hessels at UvA.
           Would be very nice to extend frequency coverage further
           down and again would broaden our consortium (and include a  potential
           co-PI .... Joeri van  Leeuwen). Of course: consult Joeri. I did not, but I know
           Joeri well.

So: all GW related. What else could I say ... I guess the GW content could be
very strong ....
