The neutron fluxes of D–D and D–T tubes with sorbed and stuffed targets are compared. Calculations of the change of the neutron flux in generators when a tube of one type is replaced by a tube of a different type are presented. The influence of the atomic-molecular composition of the ion beam and the target material, the hydride stoichiometry, and the isotopic composition of the gas in the getter is taken into account in the calculations. When replacing a D–T tube with a sorbed target by a D–D tube, the flux as a function of the accelerating voltage and atomic-molecular composition of the ion beam decreases by 100–300-fold. If a D–T tube with a stuffed target was used initially, then the change is 50–100-fold. When replacing a D–T tube with a sorbed target by a tube with a stuffed target and a predominantly molecular-ion beam, the flux decreases approximately three-fold. The tube fabrication time must be taken into account when comparing D–T tubes.
