The paper presents a system for automation
of thermal field electron source emission studies. The system tests on ZrO/W
heterostructures have shown that the developed automation system completely
meets the speci-fied technical requirements. The experiments on studying
the emission properties of ZrO/W heterostructures based on this automation
system have for the first time demonstrated that at certain conditions these
structures are capable of stable thermal field emission of ultrahigh brightness
electron beams.
