Creatingknowledge Annual Report 2012 | Forschungszentrum Jülich 41 * The number of users was lower in 2012 than in the pre- vious years, because an experimental facility (‘Big Karl’) was taken out of operation. COSY is like a microscope for the components of a nucleus – the protons and neutrons. Ever since the particle accelerator was put into operation in 1993, applications have been made for significantly more beam time than Forschungszentrum Jülich can actually provide. A Program Advisory Committee made up of internationally recognized physicists from the USA and Europe de- cides which applications be will accept- ed. Applications are submitted by inter- ested scientists from universities abroad and in Germany, as well as by COSY cooler synchrotron Jülich researchers. In December 2012, the 2 MeV electron cooler that was planned jointly with the Russian Budker Institute was delivered to Jülich from Novosibirsk. It was installed in the COSY ring in spring 2013 and will be put into operation in summer 2013. It will be used to investigate accelerator physics issues such as electron cooling. These studies will also serve its qualification as an injection cooler for the accelerator ring HSER in the international project FAIR (Facility for Antiproton and Ion Research).

At the same time, it is the first national user centre for high-resolution electron microscopy. Around 50% of the measuring time on the three Titan microscopes (PICO, TEM, STEM) at ER-C is made available to universities, research institutions and industry. This time is allocated by a panel of experts nominated by the German Research Foundation (DFG).
