ABSTRACT:
A micro-channel plate for use in focusing X-rays or particles of equivalent wavelengths has a radially packed array of square pores. For focussing parallel rays, such micro-channel plate may consist of two square-pore spherically curved and radially packed micro-channel plate elements having different radii of curvature and overlying one another, forming a concavo-convex compound plate. Such a plate is capable of providing a greater effective area than prior art square packed micro-channel plates at high X-ray energies.
