FAMU
Goals
FAMU - Fisica degli Atomi MUonici - Muonic Atom Physics
FAMU is an international collaboration involving 13 institutions and about 20 scientists.
The goal of the FAMU experiment is the measurement of the proton Zemach radius with the measurement of the hyperfine splitting of the muonic hydrogen ground state.
This measurement is motivated by the interest to deeply understand the electromagnetic structure of the proton; a new result can give a boost to resolve the present ambiguities about its structure. Moreover the FAMU experiment can be seen as a precision QED theory test.
The experimental apparatus consists in a cryogenic and pressurized gas target, filled with a gas mixture of hydrogen and a small concentration of a high Z gas.
The target is surrounded by X-ray detectors.
The experiment is placed at the RIKEN-RAL muon facility where a high intensity muon beam is produced.
Counting the number of the X-rays emitted by the de-excitation of the Z atom as function of various laser energies it is possible to obtain a resonance plot peaked at the hyperfine energy value.

Work with us
Working in FAMU is an opportunity for an inclusive experience: it is an international collaboration (Italy, Bulgary, Poland, Japan, India, and China) yet small enough to allow and encourage its members to work on a wide range of activities. From setting up the detectors before an acquisition run, to deeply understand the various aspect of the experiment, ranging from the hardware to the physics and to most theoretical point of view.
