Second hand generator needed in Cuba

Dear colleagues, our old high voltage tube-based generator from the GDR has denitely died albeit our care to have it working. This generator used to feed an x-ray tube for a texture and a double crystal goniometer, the only ones available in Cuba. Our Bragg-Brentano goniometer is presently working very well with an ENRAF NONIUS Diffractist 581 generator donated by Utrecht U., which encourages us to ask for help from our researcher colleagues. Making the aforementioned goniometers operational will benet not only Havana U., where we work, but also the Cuban materials science community, taking into account the limited availability of x-ray diffraction equipment in the country.
