A new detector technique using triangular scintillating strips to measure the position of minimum ionizing particles

We present a new technique for measuring the position where a charged particle transits a detector which achieves a position resolution much better than the granularity of the detector. This is accomplished by using scintillating strips with a triangular cross-section and an axial wavelength shifting fiber readout. We tested strips with a base of 9 mm and a height of 4.5 mm and achieved a position resolution of 567 mu m with over 60000 cosmic ray data points per strip, we are able to precisely characterize the performance of this detector design. In addition, we offer suggestions for future improvements in the achievable position resolution. Additional performance results, including uniformity and yield, are also discussed.
