Cvd-diamond-based Position Sensitive Photoconductive Detector for High-flux X-rays and Gamma Rays
A position-sensitive photoconductive detector (PSPCD) using insulating-type CVD diamond as its substrate material has been developed at the Advanced Photon Source (APS). Several different configurations, including a quadrant pattern for a x-ray-transmitting beam position monitor (TBPM) and 1-D and 2-D arrays for PSPCD beam profilers, have been developed. Tests on different PSPCD devices with hi...
متن کاملSingle Crystal Diamond X-ray Lens Development
The next generation light sources such as diffractionlimited storage rings and high repetition rate free electron lasers (FELs) will generate x-ray beams with significantly increased peak and average brilliance. These future facilities will require x-ray optical components capable of handling large instantaneous and average power densities while tailoring the properties of the x-ray beams for a...
متن کاملX-ray beam monitor made by thin-film CVD single-crystal diamond.
A novel beam position monitor, operated at zero bias voltage, based on high-quality chemical-vapor-deposition single-crystal Schottky diamond for use under intense synchrotron X-ray beams was fabricated and tested. The total thickness of the diamond thin-film beam monitor is about 60 µm. The diamond beam monitor was inserted in the B16 beamline of the Diamond Light Source synchrotron in Harwell...
متن کاملCharacterisation of Single-Crystal CVD-Diamond Detectors
Recently, the quality of intrinsic CVD Diamond (CVD-D) has tremendously been improved. The replacement of the previous used silicon substrates for growth by ultra-pure HPHT Single-Crystal (SC) {100}-oriented diamond provides homo-epitaxial grown material almost free of structural defects. Nevertheless, all substrates nominally {100}oriented show a certain amount of off-angle declination from th...
متن کاملSingle-Crystal CVD-Diamond Detectors Progress Report
Figure 1: Dark current behaviour of BDS samples metallized with sputtered Cr-Au electrodes. The measurements are performed in an electric-field range Emax= ± 3.0 V/μm by controlling dI/dV < 1nA/10V. At E = ± 1 V/μm, low currents of absolute values < 10 pico amps are measured for most of the samples. These are by orders of magnitude lower currents than those obtained from electronic-grade PolyCr...
