Laser Spectroscopy Experimental Apparatus

The collaboration does not have a dedicated beamline of its own, instead it utilises equipment already installed within ISAC.

For beam delivery and manipulation, this includes both the polariser beamline and TITAN's linear radio-frequency quadrupole trap (the first trap within their trapping system). The lasers are owned by the collaboration and revolve around a single mode titanium doped Sapphire laser as well as several older dye lasers. Absolute frequency stability is obtained by transferring the frequency stability of a polarisartion stabilised helium-neon laser to those of other wavelengths by way of a custom built fabry-Perot cavity system. This system is then routinely referenced to an absolute atomic line. 

Various microwave and radio-frequency modulators are used in order to provide rapid control of the laser light in both the frequency and time domains.

Data aquisition is achieved via a custom-built TRIUMF system which was the first in this line of research to incorporate time resolution in order to fully take advantage of the temporal structure of the beams delivered out of TITAN's radio-frequency quadrupole trap.
