Design of Photon Counter in PCS Nano-Particle Size Analyzer

Article Preview

Abstract:

In view of the extremely weak scattered light in PCS nano-particle size analyzer, a photon counter consisting of a PMT, amplifier, discriminator and pulse counter is designed. A double-counter structure is adopted in pulse counter in order to realize “glue” counter. The standard polystyrene particles are measured by using this counter, and the correlation of the collected photons was implemented. The experimental results show that the counter can reach the precision of PCS nano-particle size analyzer.
