Hello All! Does anyone know if is there available in the market some sort of all-in-one device capable of keeping the crystals of a double crystal monochromator tunned? I've contacted colleagues around the globe who have similar systems running, but none of them were able to indicate me some company which still assemblies such system. It seems today's solution would be to integrate complementary peaces of hardware or even program them in software. Hope this message finds each of you well, Lucas Sanfelici Physicist Brazilian Synchrotron Light Source- LNLS (www.lnls.br <http://www.lnls.br/> ) Beam Diagnostics Group PO Box 6192 Postal Code 13083-970 Campinas-SP Brazil Phone: +55-19-3512-1153/1152 Fax: +55-19-3512-1006
