The DIRAC experiment aims simultaneously
- to measure the lifetime of
[π−π+] atoms
- to observe
[π−K+] & [π+K−] atoms
- then to measure the [πK] atom lifetime.
The setup consists of a precise
magnetic double arm spectrometer,
installed in the high intensity proton beam
of the CERN Proton Synchrotron.
