LiquidO: Simulations for Cloud Inner Detector — •Susanna Wakely for the CLOUD collaboration — Johannes Gutenberg Universität Mainz

LiquidO is an innovative technology that uses opaque liquid scintillators for particle detection. A LiquidO scintillator combines a short scattering length and a long absorption length to confine optical photons close to their creation point. A fine array of wavelength-shifting fibres is used to collect and transport the scintillation light for readout. A LiquidO detector will have unprecedented position resolution compared to current transparent scintillators and be capable of particle identification via event topology. Proof of principle has been demonstrated by two prototypes with a third currently under construction.

The Cloud collaboration is designing a 5-10 ton LiquidO anti-neutrino detector. This will be an above-ground ultra-near reactor anti-neutrino detector located in the Chooz nuclear power plant, France.

This talk will discuss simulations of the inner detector including particle identification via event topology and fibre array design. Two broad fibre array designs are considered: parallel and stereo shells. A parallel array achieves mm resolution in x and y, with z-position obtained at lower resolution from signal timing differences. A stereo shell array would improve the resolution in z but presents challenges for the design and construction of the detector.
