β¦ Synopsis
The optimal selection of mass-reflectron parameters is discussed on the basis of solutions of the equations of motion of the ions. The influence of the grid misalignment and the potential instability upon the reflectron mass-resolution is considered. The mesh parameters of the reflectron grids were found to impose the main limitation on the value of the ultimate mass-resolution. The defocusing of the ion packets at small deflection angles is shown to be negligible.

The parameters of a mass reflector combined with direct ion extraction are optimized to reduce the time-of-flight spread caused by the initial velocity distribution of ions. Under the assumption that the initial ion velocity distribution is mass independent, one can find the mass range where the spr
This paper considers a novel approach to simultaneous optimization of the adjustable parameters of all the stabilizers in multimachine power systems to obtain the best dynamic performance. It is based on frequency domain analysis using the domainseparation method, Nyquist's stability criterion, and
