In the frame of the EU-funded project "FleX-RAY", an inherently flexible X-ray, imaging detector using single-photon avalanche photodiodes and inorganic scintillating fibres was developed. Silica-based scintillating liquid-filled fibers were developed for constructing the detector hardware.

This archive contains the following data:

RISE_DS01

• Evaluation of splice coverings to block stray light Evaluation of splice coverings to block stray light: Different types of painting methods were applied to the splice sections of the silica-scintillating components to block stray light entering the fibers. Light levels were measured and evaluated for different lightness conditions, measured by a photon counter and high-speed oscilloscope at the fiber output. The stray light was measured when the lightness condition was darkness, ambient light, and desk lamp light. The painting methods include splice without paint, black pen marker, black acrylic paint, and black spray paint.

RISE_DS02

• Silica Fiber Components Scintillating Signal using UV Illumination: Capillary fiber filled with scintillating liquids (BC505 and Perovskite quantum dots) exposed to UV source (LED- emitting at 275 nm) at specific positions along the fiber length. The scintillation count was then measured by the spectrometer (Ocean Optics Spectrometer-QEB1624) at the fiber output. The data files contain light power measurements which are compressed (filename "DATA - Silica Fiber Components Scintillating Signal UV Illumination.zip") and are presented in the folders named by measurement dates.
• Silica Components_splices and setups photos: The pictures in this folder include the experimental setups for loss measurement, UV illumination tests, filling the capillary, images of splicing the liquid-filled capillary (50µm) and MMF for components, and prototypes in this work. 
• Silica Fiber Components Scintillating Signal using X-ray illumination: Capillary fiber filled with scintillating liquid (BC505) exposed to the X-ray source (Liquid-metal-jet source, 70kV, 125W). The scintillation count was then measured by the spectrometer at the fiber output. For comparison with silica-based scintillating components, some tests were performed with plastic scintillating fiber (PSF).

RISE_DS03 

• Scintillating Silica Fiber_Deliverable Video_and_Conferene-paper: This archive contains a publication and video presentation of the design and fabrication of flexible, liquid-filled scintillating fibers for X-ray detection made from silica fibers and silica capillaries. The scintillating fibers were characterized using ultraviolet light exposure and we also performed an experiment demonstrating X-ray detection.
