The BASE experiment planned at the Antiproton Decelerator (AD) at CERN aims at a high-precision measurement of the magnetic moment of the antiproton. The heart of the apparatus consists of a stack of four cylindrical Penning traps. These traps will be used for catching and storing of antiprotons from the AD, and for the magnetic moment measurement, which will be carried out by application of the continuous Stern-Gerlach effect. Six cryogenic single particle detection systems, each consisting of a high-Q resonator and a low-noise amplifier, are planned and currently under construction. These detection circuits will be used for precision measurements of the particle*s eigenfrequencies, giving direct access to the particle*s fundamental properties. In this talk, an overview of the detection systems and status of the construction and characterization will be presented.
