Methods of putting cuts up to 6-8 mm in depth without damaging the pixel floor have been worked out, i.e. mechanical operation of a crystal does not lead to its cracking along the cleavage surface. The detector prototype with the surface formed by cuts has been produced and investigated.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
