Abstract

The X-ray imaging with Micro-Pore Optic (MPO) plates can provide huge field of view with light mass, which will be applied for the Wide-field X-ray telescope (WXT), one of the two payloads onboard China’s Einstein Probe (EP) mission. Since each MPO plate has millions of micro square pores with width of 20 μm which actually behave as honeycomb materials, the mechanical properties of the MPO plates will be much more complex than normal optical glass as homogeneous material. This work estimated the mechanical properties of MPO plates, provided an equivalent mechanical properties as homogeneous material to greatly simplify the Finite-Element Analysis (FEA). Three basic material properties of MPO plates - relative density, effective elastic stiffness (Young’s module) and the effective Poisson’s ratio are estimated and preliminary validated with FEA simulations.
