Superheated droplet detector response to fabrication variations

摘要

Constructions of superheated droplet detectors (SDDs) are easily (and sometimes unavoidably) altered in the fabrication process by small variations in the ingredient concentrations and fractionating of the superheated liquid. The devices have moreover been stored at temperatures below 0 ℃ prior to usage in order to de-sensitize their response during transport. We report studies of the response differences of high concentration SDDs with respect to variations common to their fabrication, to include ageing, concentration, gel stiffness, and droplet size.
