Angular distributions of atoms sputtered from a copper target under 5‐keV Kr+ bombardment at normal incidence were simultaneously and independently studied by experiments and computer simulation. The sputtered particles are collected on a Mylar™ foil placed around the target. Deposited particles on the substrate were analyzed by optical transmission spectroscopy. The surface roughness of the irradiated...
Advanced liquid rocket engines (LREs) are being created by Yuzhnoye Design Office of Ukraine based on the fifty-year experience of rocket engines' and propulsion systems' development. These LREs use both hypergolic (NTO+UDMH) and cryogenic (liquid oxygen+kerosene) propellants. First stage engines have a range of thrust from 40 to 250 t, while the upper stage (used in space) engines - from several...
