A Test Experiment at the Fermilab Booster to Study the Feasibility of Fast Antihydrogen Spectroscopy

Atomic antihydrogen has recently been observed at Fermilab [1]. It appears feasible to measure the principal structure, ne structure and Lamb shift of antihydrogen atoms in ight [2]. It is possible to test the proposed techniques and measure cross sections for the relevant atomic processes at relativistic velocities by rst using a proton beam. We propose to perform such a test at the FNAL Booster using 8 GeV protons, either in the old transfer line from the Booster to the Main Ring (the proposed \silicon damage" test facility) or in the permanent magnet transfer line to the Main Injector.
