Forschungszentrum Jülich - Annual Report 2012

42 Forschungszentrum Jülich | Annual Report 2012 INM focuses on the structure and function of the healthy and diseased human brain. It aims to understand the structural and functional changes caused by neurological and psychiatric disorders and thus to improve their The MRI scanners at the Institute of Neuroscience and Medicine (INM) Use of the 3 T MRI-PET hybrid scanner In clinical trials for this instrument, patients are examined in collaborative projects with different external hospitals. In 2012, 76 patientsfrom the neurosurgical departments at the universities of Düsseldorf and Cologne as well as the radiotherapy department at RWTH Aachen University were examined. An additional15 patientsfrom the Department of Nuclear Medicine at Düsseldorf University Hospital were also examined. diagnosis and treatment. Scientists work with imaging techniques such as structural and functional magnetic reso- nance imaging (MRI) and positron emission tomography (PET), as well as hybrid systems combining both MRI and PET. Several instruments are at hand in order to generate basic re- search results and to facilitate their transfer to clinical applications: 9.4 T MRI-PET (research), 9.4 T MRI (animal research), 4 T MRI, PET (re- search and clinical application), and 3 T MRI, 3 T MRI-PET (clinical applica- tion). Some of the state-of-the-art instruments for medical imaging at Jülich are also available to external researchers. MRI scanners produce high-resolution and high-contrast images of the human brain. The instruments at the Jülich Centre for Neutron Science (JCNS) JCNS operates neutron research instru- ments at leading international neutron sources. For this reason, JCNS is also responsible for the construction and operation of the Jülich instruments at Beam time (days) at FRM II allocated by JCNS in 2012 Internal users 327 Maintenance/ development 326 Training activities 40 269 External users Germany 192 External users EU 92 External users rest of world Use of the JCNS neutron scattering instruments by external researchers in 2012 (days) POLI** 29 SPHERES 60 ILL 6 SNS 29 KWS-2 53 70 BIODIFF* 47 DNS 82 HEIDI** 77 J-NSE 74 KWS-1 KWS-3 61 * in cooperation with Technische Universität München (TUM) ** operated by RTWH Aachen University BioDiff Diffractometer for large unit cell DNS Time-of-flight spectrometer with diffuse neutron scattering HEIDI Single crystal diffractometer on hot source J-NSE Jülich neutron spin echo spectrometer KWS 1 Small-angle scattering facility 1 KWS 2 Small-angle scattering facility 2 KWS 3 Small-angle scattering facility 3 POLI Polarized hot neutron diffractometer SPHERES Backscattering spectrometer with high energy resolution ILL Institut Laue-Langevin, Grenoble SNS Spallation Neutron Source, Oak Ridge (estimate) the Heinz Maier-Leibnitz research neutron source (FRM II) in Garching near Munich.
