Abstract

The ALPHA apparatus combines a variety of components and experimental techniques in order to produce, trap, and study antihydrogen. The physics involved in these components and techniques is interesting in its own right—but here it is important to give a general description of the ALPHA experiment and antihydrogen trapping scheme.

Notes

  1. 1.

    AD website: http://psdoc.web.cern.ch/PSdoc/acc/ad/

  2. 2.

    As shown in Fig. 3.6, a transmission line diagonal to the storage ring is used for the stochastic cooling system. This shortcut allows the beam correction to be applied to the same particles that were measured at the pickup.

  3. 3.

    Some mixing schemes start with the antiprotons at the bottom of a side-well (to be discussed in Sect. 3.4.5). The antiprotons are then rf-driven into the positron plasma to produce antihydrogen. Here again, the presence of electrons would be counter-productive, as the antiprotons would be cooled back into the side-well and would need to be driven back into the positron plasma.
