✦ Synopsis
A novel scintillation detector is being developed with standard microfabrication techniques. It consists of a dense array of scintillating waveguides obtained by filling microfluidic channels with an organic liquid scintillator. Such a microfluidic device can be designed and processed to meet the requirements of a wide range of applications like medical imaging, homeland security and high-energy physics. High-spatial resolution miniaturized detectors as well as large-area detectors can easily be fabricated. This paper presents the fabrication process of a prototype detector with 200 μm × 50 μm microchannels obtained by photolithography of the SU-8 photoresist. Preliminary experimental results are presented.
