Abstract

An analytical X-ray tube with an anode target material that emits characteristic X-rays in response to excitation by an electron beam may include any of several advantageous features. The target material is deposited on a diamond substrate layer, and a metal carbide intermediate layer may be provided between the target material and substrate that provides enhanced bonding therebetween. An interface layer may also be used that provides an acoustic impedance matching between the target material and the substrate. For a low thermal conductivity target material, a heat dissipation layer of a higher thermal conductivity material may also be included between the target material and substrate to enhance thermal transfer. The target material may have a thickness that corresponds to a maximum penetration depth of the electrons of the electron beam, and the structure may be such that a predetermined temperature range is maintained at the substrate interface.
