Abstract: A production method for producing an anode for a cold cathode X-ray source, including the following steps: producing an element referred to as target from a first material adapted to generating X-rays from the absorption of an electron beam, the first material having a first thermal expansion coefficient Ce,1(Tu) at a predetermined temperature Tu of use of the anode in the X-ray source, producing an element referred to as target support from a second material having a second thermal expansion coefficient Ce,2(Tu) at the predetermined temperature Tu, joining the target to the target support by hard soldering using a solder material at a soldering temperature higher than the predetermined temperature Tu and higher than a melting point of the solder material, so as to form a film of solder interposed between the target and the target support.
