Feasibility Study for Neutron Beam Investigation of the Turin Shroud

Abstract

In this work, the possible investigations and analyses of the Turin Shroud by Neutron Beam Techniques (NBT) are discussed. The main aim of this study is to assess-in a reliable non-destructive way and in complementarity to methods already employed or under consideration for future examination campaigns-and to determine some key parameters useful to enhance current knowledge and databases on the textile properties of the Shroud. Information to be obtained could reveal new interesting and original features with potential scientific and historical effects as well as contributing to solving problems of conservation and preservation. Preliminary results of NBT analyses carried out on new and aged linen fibres illustrate some information that could be gained when using NBT on the Turin Shroud.

PIXE Investigation of Ancient Linen Fabrics Dated from Old Kingdom to Ptolemaic Ages (2200-300 B.C.)

“…Linen fibres are an extremely stiff material in the longitudinal direction of the fibre; the macromolecules are generally oriented in the same direction. Since plant cell walls, they can be considered as composites made of cellulose nano-crystals (micro-fibrils) embedded in a disordered matrix [1].…”
