“…We have already demonstrated the imaging of cosmic muons with a 40 litre LAr ARIADNE prototype TPC utilising a THGEM and Electron Multiplying CCD (EMCCD) camera [13,14]. ARIADNE is a research project for the development of innovative optical two-phase LArTPC readouts [15][16][17][18]. This paper presents exciting progress that has been made in optical readout methodology.…”

A : The ARIADNE project is developing innovative optical readout technologies for two-phase liquid Argon time projection chambers (LArTPCs). Optical readout presents an exciting alternative to the current paradigm of charge readout. Optical readout is simple, scalable and cost effective. This paper presents first demonstration of 3D optical readout of TPC, using CF 4 gas as a proof of principle. Both cosmic rays and an Americium-241 alpha source have been imaged in 100 mbar CF 4 . A single-photon sensitive camera was developed by combining a Timepix3 (TPX3) based camera with an image intensifier. When a pixel of TPX3 is hit, a packet containing all information about the hit is produced. This packet contains the x, y coordinates of the pixel, time of arrival (ToA) and time over threshold (ToT) information. The z position of the hit in the TPC is determined by combining drift velocity with ToA information. 3D event reconstruction is performed by combining the pixel's x, y location with this calculated z position. Calorimetry is performed using time over threshold, a measure of the intensity of the hit.
