The Center for Micro-Analysis of Materials (CMAM) is a research center belonging to the Autonomous University of Madrid (UAM), the result of an initial project funded through the FEDER program, assisted by an Advisory Committee made up of outstanding members of the Spanish scientific, cultural and academic community.

The main experimental tool of the CMAM is an electrostatic ion accelerator with a maximum terminal voltage of 5 million volts, dedicated to the analysis and modification of materials. The CMAM operates its accelerator with six beam lines, complemented by several ancillary scientific tools and laboratory support spaces. These lines are available for material analysis and modification: Multipurpose Standard Line (STD), External Microbeam Line (EuB), Flight Time Line (ERDA-TOF), Nuclear Physics Line (NUC), Implantation Line (IMP) and Femtosecond Laser and Internal Microbeam Line (IuB).
