MIRACLS experiment

The Multi Ion Reflection Apparatus for Colinear Laser Spectroscopy (MIRACLS) is a permanent experiment setup being constructed at the ISOLDE facility at CERN.

[1] Collinear laser spectroscopy is a technique allowing the measurements of properties of nuclei, such as ground state spins, electromagnetic moments and charge radii.

[4] The potentials are set to optimise trapping and focusing, whilst also keeping the central drift region of the device free of fringe (outer magnetic) fields.

[7] The ODR consists of an optical lens system and photomultiplier tube (PMT) to detect fluorescence photons emitted by the excited Mg+ ions, mounted above the mesh electrode.

[6] MIRACLS aims to increase the sensitivity of the fluorescence collinear laser spectroscopy technique, conventionally used for hyperfine measurements (e.g. COLLAPS).
