Spatially coherent X-rays are a potentially useful source for imaging biological and crystalline material at nanometre length scales [1]. Such radiation can be produced via high harmonic generation (HHG), commonly achieved by focussing a high-energy ultrashort laser pulse into ajet of noble gas [2]. However, gas jets have a complex three dimensional density and velocity profile [3], and since the generation efficiency depends on both the density of nonlinear material present and the degree of phase matching, the profile of the gas jet can have a significant influence on the generation process.
