D-D fusion reaction cross-section measurement in 70~250 keV energy range

The experimental energy range spanned from 70 keV to 250 keV. A thin deuterated polyethylene target of 121 nm was used in the experiment.

The fusion reaction chamber with eight angles equipped with PIPS detectors can detect the reaction products of charged particles from eight perspectives. Using deionized water to cool the target, and using picoammeter to measure the target current. The Legendre polynomials were used to fit the experimental differential cross-sections.
