Notes:
A compact two-grids mirror is described. Although analytical calculations and computer simulations are useful it is found that experimental adjustments of the mirror voltage and of the bias divider resistors are needed to achieve the optimum performance. The experimental procedure is given. It is shown that a second-order time-focusing mirror is appropriate for metastable-ion studies with high mass resolution. Large variations of sample voltage can be compensated by the mirror. Thick insulators can be analysed.
