The possibility of using a position-sensitive gas scintillation proportional counter (GSPC) as a sensitive element at the 'focus' of a coded-mask telescope is severely limited by the effects of penetration depth of the incoming X-rays on the spatial resolution of the instrument. Here, measurement results are reported which support the feasibility of exploiting primary scintillation in xenon as a fast trigger for deconvolving off penetration depth effects of energetic X-rays. The application of the technique to high-pressure, position-sensitive GSPCs when used in conjunction with wide-field coded masks is discussed.
