Abstract

When investigating the dusty plasmas in a magnetic field, there are a number of problems in creating stable dust structures. This is particularly evident in stratified discharge at fields above 1000 G. This report discusses the conditions of the experiment under which for the first time it was possible to create the stable dust structure in the glow discharge with fields up to 10 000 G. The areas of stability and instability of the dust trap have been detected depending on discharge parameters such as a gas sort, a pressure, a current and a radius of discharge tube. The conditions of instability are compared with the literary data on the properties of the glow discharge in plasma. The general recommendations for the creation of the stable dust structure are concluded.
