DETECTION OF ELECTRONS IN A COMBINED TRAP BY PHASE MODULATION OF THE CONFINING MICROWAVE FIELD

The unique capability to confine particles with opposite charge and ve ry different mass simultaneously in the same spatial region makes tile combined trap a promising device for future synthesis of antihydrogen . For recombination experiments it is desirable to detect particles in the combined trap non-destructively. A detection scheme is proposed f or that purpose which is based upon the interaction between stored ele ctrons (or positrons) and the field in the microwave trap resonator.
