Monitoring of the Target Surface During Experimental Study of the D(d,n)3he Reaction at Ultralow Collision Energies

Data on the growth rate of an adsorbed film on a target are obtained using a quartz resonator upon operation with an accelerator with closed electron drift. The target is shown to be purified at 55°C and a flux of accelerated (12 keV) deuterium particles (about 5 × 1012 cm–2) and the dynamic equilibrium of sorption and desorption processes is established. The yield of neutrons increases during the d(d,n)3He nuclear reaction due to purification of the target.
