Kappa Six-Circle Goniometer for Cornell University

ADC custom designed and built a six circle kappa Goniometer for G2 line at CHESS. Cornell had six rotation from Huber and wanted to utilize those for this application. They had very stringent requirements and Huber standard six circle Goniometer could not meet the requirements. There had to be significant custom design, finite element analysis, and calculations done for this project.

All axes were perfectly counterbalanced to provide the very high accuracies at any accessible angular position. Our design incorporated advanced material and construction techniques resulting in lightweight yet rigid systems to improve dynamic performance with larger loads and higher velocities at extremely high precisions. The six-circle Kappa Goniometer was designed to handle heavy loads. It included collimator and detector arms with adjustable holders for collimators, slits, various size cryostats, heat chambers and vacuum chambers.
