Characterization of the Deformation Field Near the Crack-Tip after Bending by Small Angle X-ray Scattering

Böhmert, J.; Große, M.

The inhomogeneous deformation field ahead the crack tip of pre-cracked and bended Charpy-V specimens was monitored by scanning with a highly focussed X-ray beam at the Synchrotron Radiation Facility (ESRF). The measured scattering pattern shows two characteristic features:

streak-like anisotropic scattering with different symmetry
isotropic scattering.

The streaks are produced by scattering at the grain boundaries. The slope of the Guinier plot of the scattering intensity in the streaks yields an effective scattering thickness of the grain boundary of 1.4 nm. The isotropic scattering intensity can be explained as scattering at the dislocation structure. Its dependence on the scattering vector follows a Porod law with exponents between -3.3 and -2.8. The local distribution of both the integral scattering intensity and the Porod exponent reflect the shape of the plastic zone ahead of the crack tip.
The results demonstrate that small angle X-ray scattering with a scanning microfocussed beam provides a new method to characterize inhomogeneous deformation states with a resolution of few micrometers.

Untersuchung zur Strahlenbelastung des medizinischen Personals bei [¹⁸F]FDG-PET-Studien

Linemann, H.; Will, E.; Beuthien-Baumann, B.

Untersucht wurde die Strahlenbelastung des medizinischen Personals bei wesentlichen Arbeitsschritten von PET-Untersuchungen. Die Wirksamkeit von selbst entwickelten Strahlenschutzeinrichtungen und Arbeitsanweisungen wurde geprüft.
Methode: Die Personendosis und die Handdosis wurde für die einzelnen Arbeitsschritte bei [¹⁸F]FDG-Untersuchungen mit direkt ablesbaren Personendosimetern bzw. Thermolumineszenzdosimetern gemessen. Ergänzend wurden Ortsdosisleistungsmessungen durchgeführt.
Ergebnisse: Die mittlere Personendosis pro PET-Untersuchung betrug für die Spritzenpräparation 1 Sv, für die Injektion 3 Sv, für die Blutabnahme sowie für die Patientenlagerung und -betreuung je 6 Sv. Als mittlere Handdosis pro PET-Untersuchung wurden bei der Spritzenpräparation 710 Sv für die rechte und linke Hand und bei der Injektion 13 Sv für die rechte sowie 27 Sv für die linke Hand ermittelt. Alle Werte wurden unter Verwendung der im PET-Zentrum Rossendorf eingesetzten Strahlenschutzvorrichtungen und -maßnahmen gemessen.
Schlußfolgerung: Die entwickelten Strahlenschutzvorrichtungen gewährleisten die sichere Einhaltung der Jahresgrenzwerte für die Personendosis. Eine Ausnahme bildet die hohe Handdosis bei der Spritzenpräparation. Hier sollte eine automatische oder fernbedienbare Fülleinrichtung eingesetzt werden, wenn mit mehr als etwa 500 PET-Untersuchungen im Jahr gerechnet wird.

The aim of the investigation was the identification of those working steps with the highest radiation exposure for the medical personnel during [¹⁸F]FDG-PET studies and to evaluate the effectiveness of radiation protection devices and instructions applied.
Methods: The personal dose and hand dose were measured for each working procedure during [18F]FDG-PET studies using electronic personal dosimeters and thermoluminescent dosimeters respectively. Additionally, measurements of the radiation level in proximity of the patient were taken.
Results: The mean personal dose resulting from syringe preparation was 1 µSv/syringe, from injection 3 µSv/patient, from blood sampling during quantitative studies 6 µSv/study, and from positioning and handling of the patient 6 µSv/study. The mean hand dose per syringe preparation was 710 µSv for each hand. The mean hand dose during injection was 13 µSv for the right hand and 27 µSv for the left hand. All above mentioned values were measured applying the routine radiation shielding in use in our PET center.
Conclusion: With the developed radiation shielding and means to reduce radiation exposure applied the allowed annual dose for medical personnel are not exceeded. One exception could be the hand dose resulting from syringe preparation. If more than 500 PET investigations per year are expected, an automatic or remote filling device should be considered.

We investigated the influence of phenolic OH groups on the complexation behavior of humic acids (HA's) with UO22+ ions at pH 4. Starting from the synthetic HA type M1, the natural HA Aldrich, and the natural HA Kranichsee, we synthesized modified HA's with blocked phenolic OH groups by derivatization with diazomethane. The partial blocking of phenolic OH groups was confirmed by a radiometric method which quantitatively determined the functional groups and by FTIR spectroscopy. The complexation behavior of the modified and unmodified HA's with UO22+ ions was investigated by time-resolved laser-induced fluorescence spectroscopy. The experimental data were evaluated with the metal ion charge neutralization model. We determined comparable complexation constants for all HA's. Two modified HA's (type M1 and Aldrich) had significantly lower loading capacities with UO22+ ions (10.5 ± 0.9 % and 9.7 ± 1.6 %, respectively) than the corresponding unmodified HA's (18.0 ± 2.0 % and 17.5 ± 1.6 %, respectively). This indicates that the blocking of the phenolic OH groups changes the complexation behavior of the HA's.

Keywords: Humic acid; synthetic humic acid; modified humic acid; phenolic OH groups; complexation; uranium

Structural mechanisms of the mechanical degradation of Ti-Al-V alloys: in-situ study during annealing

Berberich, F.; Matz, W.; Richter, E.; Schell, N.; Kreißig, U.; Möller, W.

Aim of the work is to investigate the structural mechanisms of the enhanced hardness of the technical alloy Ti-6Al-4V due to N+ implantation and its degeneration. Ti-6Al-4V samples were implanted with doses (1 - 6) x 1017 N+/cm2 at 80 keV. The structural implications of the loss of hardness during annealing were studied by in-situ XRD-experiments with synchrotron radiation. Additional sample characterisation was performed by SEM, ERDA and Vickers hardness. The hardness reduction due to annealing is caused by phase transformation from TIN to Ti2N as well as by rearrangements in the alpha-Ti and beta-Ti phase of the alloy.

Keywords: Ti-6Al-4V; ion implantation; XRD; hardness

The Drossel collaboration was established for the development of a low emittance high average current injector for the ELBE project. The injector is based on a photocathode RF gun with a superconducting cavity. The high average current is especially important for applied research and other applications. First tests of the gun cavity has been done at DESY TTF.

Keywords: Drossel cooperation; superconducting RF gun; DESY TTF; applied research; photocathode; high average current
