Abstract
The invention relates to an energy-focusing and space-angle focusing reflector for time-of-flight mass spectrometers. The invention consists in producing an adjustable space-angle focusing system by means of an adjustably weaker field with curved equipotential lines at the end of the reflector instead of a fully homogeneous electrical reflection field.
