Nowadays, for solving new problems, rocket engine nozzle developers are increasingly turning to non- traditional configurations that differ from the classic Laval one. A relatively line in design of supersonic nozzles is development so-called bell-shaped nozzle, which, unlike classical has a larger angle entry into part nozzle. In this case, dual bell nozzles, which have two flow expansion sect...

For high precision storage ring experiments as the future P̅ANDA experiment, very sophisticated internal targets have to be used. this purpose, a state-of-the-art cluster-jet target was developed at University Münster. Basically, hydrogen is cooled cryogenic temperatures and pressed through specially shaped Laval nozzle form expanding into vacuum. Due stability large mass of clusters, practicall...
