Abstract :
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 μm. With over 60 000 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.
