AbstractAbstract
[en] A high resolution measurement of the 16O(γ,p)15N cross section to the low-lying states is a sensitive probe of the role of meson-exchange currents in photoabsorption. This reaction was measured with tagged-photons of energy Eγ = 40 and 60 MeV, at the Lab. of Nuclear Science of Tohoku University. Experimental conditions were optimized to provide the best possible resolution. Consistent with earlier observations, it was demonstrated that the major strength in the cross section is derived from photon-absorption by meson-exchange currents. It was also confirmed that the population of the positive-parity states is significant. 6 refs., 1 fig

AbstractAbstract
[en] PILATUS systems are well established as X-ray detectors at most synchrotrons. Their single photon counting capability ensures precise measurements, but introduces a short dead time after each hit, which becomes significant for photon rates above a million per second and pixel. The resulting loss in the number of counted photons can be corrected for by applying corresponding rate correction factors. This article presents a Monte-Carlo simulation, which computes the correction factors taking into account the detector settings as well as the time structure of the X-ray beam at the synchrotron. For the PILATUS2 detector series the simulation shows good agreement with experimentally determined correction factors for various detector settings at different synchrotrons. The application of more accurate rate correction factors will improve the X-ray data quality at high photon fluxes. Furthermore we report on the simulation of the rate correction factors for the new PILATUS3 systems. The successor of the PILATUS2 detector avoids the paralysation of the counter, and allows for measurements up to a rate of ten million photons per second and pixel. For fast detector settings the simulation is capable of reproducing the data within one to two percent at an incoming photon rate of one million per second and pixel.

AbstractAbstract
[en] MYTHEN is a single photon counting hybrid strip X-ray detector that has found application in x-ray powder diffraction (XRPD) experiments at synchrotrons worldwide. Originally designed to operate with hole collecting silicon sensors, MYTHEN is suited for detecting X-rays above 5 keV, however many PD beamlines have been designed for energies above 50 keV where silicon sensors have an efficiency of only few percent. In order to adapt MYTHEN to meet these energies the absorption efficiency of the sensor must be substantially increased. Cadmium-Telluride (CdTe) has an absorption efficiency approximately 30 times that of silicon at 50 keV, and is therefore a very promising replacement candidate for silicon. Furthermore, the large dynamic range of the pre-amplifier of MYTHEN and its double polarity capability has enabled the characterisation of an electron collecting Schottky type CdTe sensor. A CdTe MYTHEN system has undergone a series of characterisation experiments including stress test of bias and radiation induced polarizations. The performance of this system will be presented and discussed

AbstractAbstract
[en] Recent advances in hybrid pixel detectors (HPD), motivated by the stringent demands of high-energy-physics experiments, have made a new type of spectroscopically-enabled photon-counting detector feasible. These developments could lead to improved imaging in medical and tomographic applications where detector noise currently imposes limitations. PSIMOD is a generalised system model based on a combination of GEANT4, the TCAD semiconductor simulation package and the SPICE analogue circuit simulation program. It has been developed to reproduce the response of the analogue front end of a pixelated single photon counting detector. With this suite of correlated simulations, it is possible to quickly characterise different system configurations for various detectors.

AbstractAbstract
[en] The 12C (γ,p) reaction was studied. The experiment was done at the MAX Laboratory of Lund University, using tagged photons with energy between 50 and 70 MeV and natural carbon targets. It has been possible to detect γ-ray emitted from the residual nucleus, in coincidence with photoprotons leading to the excited residual state. The 200 KeV gamma-ray resolution permitted the identification of the residual states and allowed off-line cuts to be made in order to identify the excitation region in 11B from what particular de-excitation gamma-ray were seen. 9 refs., 1 tab., 3 figs

AbstractAbstract
[en] Use of residual-state decay γ-rays could be a powerful tool in the study of photonuclear reactions. The practicality of this technique in a tagged-photon experiment is demonstrated for the first time with data on the 12C(γ, p) reaction, with the aim of resolving the relative population of the three states around 7 MeV. It was found that the population of the 7.29 MeV state is considerably weaker than one or both of the states at 6-8 MeV. 10 refs., 3 figs

AbstractAbstract
[en] The 40Ca(γ,n) reaction was measured using tagged photons in the energy range 25-50 MeV. Neutrons were detected using two 9-element, liquid scintillator, neutron detectors placed at angles of 55 deg and 125 deg at flight path of 3.2 m. The absolute cross section was determined relative to that for D (γ,n)p, which was measured using a heavy water target. The forward/backward asymmetry in the 40Ca (γ, n) cross section, resulting from E1/E2 interference has been used to locate and parametrize the isovector giant quadrupole resonance (IVQR). 6 refs., 2 figs

AbstractAbstract
[en] Time resolved experiments require precision timing equipment and careful configuration of the machine and the beamline. The Australian Synchrotron has a state of the art timing system that allows flexible, real-time control of the machine and beamline timing parameters to target specific electron bunches. Results from a proof-of-principle measurement with a pulsed laser and a streak camera on the optical diagnostic beamline will be presented. The timing system was also used to fast trigger the PILATUS detector on an x-ray beamline to measure the fill pattern dependent effects of the detector. PILATUS was able to coarsely measure the fill pattern in the storage ring which implies that fill pattern intensity variations need to be corrected for when using the detector in this mode.

AbstractAbstract
[en] A Monte Carlo simulation is presented, which computes the rate correction factors taking into account the detector settings and the time structure of the X-ray beam. The results show good agreement with experimentally determined correction factors. The PILATUS detector system is widely used for X-ray experiments at third-generation synchrotrons. It is based on a hybrid technology combining a pixelated silicon sensor with a CMOS readout chip. Its single-photon-counting capability ensures precise and noise-free measurements. The counting mechanism introduces a short dead-time after each hit, which becomes significant for rates above 10"6 photons s"−"1 pixel"−"1. The resulting loss in the number of counted photons is corrected for by applying corresponding rate correction factors. This article presents the results of a Monte Carlo simulation which computes the correction factors taking into account the detector settings as well as the time structure of the X-ray beam at the synchrotron. The results of the simulation show good agreement with experimentally determined correction factors for various detector settings at different synchrotrons. The application of accurate rate correction factors improves the X-ray data quality acquired at high photon fluxes. Furthermore, it is shown that the use of fast detector settings in combination with an optimized time structure of the X-ray beam allows for measurements up to rates of 10"7 photons s"−"1 pixel"−"1
