DIAGNOSTIC APPLICATION OF MULTIROW COMPUTED TOMOGRAPHY OF THE HIP JOINT OF JAPANESE QUAILS (COTURNIX JAPONICA)

ABSTRACT The morphological assessment of selected parts of the hindlimb of Japanese quails (Temminck & Schlegel, 1849), with particular emphasis on hip joint structures, was performed, using a 128-row scanner (GE Optima Aquilion, Toshiba, Japan). Eight dead 3-month-old Japanese quails were evaluated. During intravital examination of those birds, no hindlimb abnormalities or locomotion disorders were detected. Bird body, which hip joints and other structures of hindlimbs were studied, was examined in posterioranterior position. The following hip joint structures, on both sides, were assessed in this study: hip joint gap width, acetabulum width, femoral head diameter, and femoral shaft width. The applied imaging method allowed accurate assessment of the selected structures. There was low variability between left and right hindlimbs and among individuals. Modern imaging techniques, such as multirow computed tomography (MCT) allows quick intravital assessment of normal and pathological structures of poultry bones and joints

LLRF COMMISSIONING OF THE EUROPEAN XFEL RF GUN AND ITS FIRST LINAC RF STATION

Abstract The European X-ray free electron laser (XFEL) at the Deutsches Elektronen-Synchrotron (DESY), Hamburg Germany is in its construction phase. Approximately a third of the super-conductive cryomodules have been produced and tested. The RF gun is installed since 2013; periods of commissioning are regularly scheduled between installation phases of the rest of the injector. The first linac, L1, consisting of 4 cryomodules powered by one 10 MW klystron is installed and being commissioned. This contribution reports on the installation and preparation work of the low-level radio frequency system (LLRF) to perform the commissioning of the XFEL first components. The commissioning plans, schedule and first results are presented
