Technical Design Report BASE

We propose a direct high-precision measurement of the magnetic moment, or g-factor, of a single antiproton stored in a cryogenic Penning trap. Currently the most precise value of the magnetic moment of the antiproton is extracted from super-hyperfine spectroscopy of antiprotonic helium atoms, and kn...

Sumario:We propose a direct high-precision measurement of the magnetic moment, or g-factor, of a single antiproton stored in a cryogenic Penning trap. Currently the most precise value of the magnetic moment of the antiproton is extracted from super-hyperfine spectroscopy of antiprotonic helium atoms, and known with a relative precision of only about 3 10^{-3}. BASE aims at a measurement with a relative precision of 10^{-9} or better. A Letter of Intent which was submitted to CERN was welcomed by the SPSC and we were invited to submit this Technical Design Report.
