Abstract:
Lowering the manufacturing complexity of position-sensitive detectors (PSDs) while retaining their performance has always been challenging. Here, we introduce a delay-line PSD for direct usage in charged ion beam detection. The system, fully constructed using printed circuit board assembly, greatly reduces manufacturing complexity while maintaining excellent detection performance. A structurally simple and stable serpentine delay-line anode was fabricated using a commercially available printed circuit board. Combined with constant fraction discriminator-based high-precision readout electronics and a field programmable gate array chip, the system achieves full width at half maximum resolutions of 210 and 350 μm along the X and Y axes, respectively.
