5. Life Cycle of Interstellar Medium (ISM)
Fine structure lines, Carbon, Oxygen, and Nitrogen, to probe all relevant phases of the interstellar medium from dense, warm, molecular interfaces to ionized gas
NII: 1.4 THz
CII: 1.9 THz
OI: 4.7 THz
1 THz=100 µm
Need one slide for transition BEFORE this slide – tell us what GUSSTO is in very general terms with a nice image. You need some excuse to say that the key to addressing those objectives is a telescope with the proper characteristics and observing profile, and we’ve learned how to do it over the past decade. Then you can jump into this more detailed discussion of exactly how we answer the questions.

15. Current NbN mixers have too small IF bandwidth
Plan joint research
Current NbN mixers have too small IF bandwidth
New material MgB2 can increase this by a factor 3 or 4
PMO and SRON/TUD work together on design, measurement, and analysis. Fabrication at TUD
Thin MgB2 comes from Dr. Yue Wang, Beijing University by HPCVD
PLD deposition of MgB2 is planned also in the Delft Kavli Institute
