Development status of a portable gadolinium monitor using laser-induced luminescence

Iwata, Yoshihiro ; Sekiya, Hiroyuki*; Ito, Chikara

A portable monitor using laser-induced luminescence of gadolinium ions in water is under development for real-time measurements of gadolinium ion concentration and emission lifetime without water sampling. This monitor is equipped with a laser irradiation cell connected to the sample tube, where gadolinium ion luminescence is generated by a ns pulsed laser at 266 nm and detected by a photomultiplier tube with a bandpass filter. Detailed design work is currently underway.
