Future Prospects and Conclusion

The magnetic confinement of antihydrogen makes possible a number of interesting experiments. Generally, these experiments require the antihydrogen atoms to remain in the neutral-atom trap for long enough to complete the given measurement. Indeed, the study of antihydrogen has been, so far, mainly concerned with the production of antihydrogen, as the atoms vanished almost immediately after formation. This chapter will first describe another recent ALPHA result: the confinement of antihydrogen for as long as 1000 s. This result then motivates discussion of possible mid- and long-term measurements with trapped antihydrogen, specifically, microwave and laser spectroscopy of antihydrogen. Finally, some remarks to conclude this dissertation will be given.
