Request for equipment

Dear Colleagues

Despite years of intensive care, our old high voltage tube-based generator from the GDR has definitely died. This generator previously used for texture analysis and a double crystal goniometer are the only ones available in Cuba. Our Bragg-Brentano goniometer is presently working well with an ENRAF NONIUS 581 generator donated by Utrecht U., which encourages us to ask for donated equipment from our colleagues. Acquisition of a functioning generator would benefit not only Havana U., but the Cuban materials science community in general.
