Preparation of Experiments for Parabolic Flight Campaign in October 4-14, 2005.
Participants: 
Fink, Höfner, Kretschmer, Seurig (ground support), Tarantik, Thoma, Usachev, Zobnin
Experiments:
1st day: Lavalle nozzle, cloud collisions 
2nd day: cloud collisions, solitary waves 
3rd day: manipulation laser, dc-modulation 
Remarks: 
Cleaning by gas flow shall be investigated.
Cloud collisions and solitary waves have to be tested in parabolic flight rack
in the lab first (until beginning of August) by Michael Kretschmer. In particular
the rf-generator (power) has to be selected. IHED should provide information for
testing the solitary wave experiment. 
The experimenters shall provide a flow chart of their experiments to Karl Tarantik.
The procedures of the experiments have to be written until beginning of September.

Discussion on future developments: 
DLR project (Feb. 2005-Jan. 2008): Continuation of PK-4 laboratory phase
(1 position, IHED subcontract), additional money for purchasing a camera/laser
system (3 CMOS cameras plus strong illumination laser) granted.
ESA Phase A/B: Work packages for MPE and IHED presented and discussed 
Note: only developments can be financed, not scientific investigations
Preparation of offer: First KT/MPE meeting end of July; request beginning
of August; offer finished by end of August (apart from input from IHED
beginning of September)
