    • Tuning forks with optimized geometries for quartz-enhanced photoacoustic spectroscopy 

      Patimisco, Pietro; Sampaolo, Angelo; Giglio, Marilena; dello Russo, Stefano; Mackowiak, Verena; (2019)
      We report on the design, realization, and performance of novel quartz tuning forks (QTFs) optimized for quartz-enhanced photoacoustic spectroscopy (QEPAS). Starting from a QTF geometry designed to provide a fundamental flexural in-plane vibrational mode resonance frequency of ~16 kHz, with a quality factor of 15,000 at atmospheric pressure, two novel ...
