Description
Spectroscopy of antihydrogen has the potential to yield high-precision
tests of the CPT theorem and shed light on the matter-antimatter
imbalance in the Universe. We will describe the progress made in the
production of a trapped sample of antihydrogen atoms at CERN's
Antiproton Decelerator. Sensitive diagnostics of the temperatures,
sizes, and densities of the trapped antiproton and positron plasmas
have been developed, which in turn permitted development of techniques
to precisely and reproducibly control the initial experimental
parameters. The use of a position-sensitive annihilation vertex
detector, together with the capability of controllably quenching the
superconducting magnetic minimum trap, enabled us to carry out a
high-sensitivity and low-background search for trapped synthesised
antihydrogen atoms.We will report results from ALPHA's recent
data-taking run and outline the prospects for the near future.
