Detectors for Synchrotron Radiation and Spallation Neutron Sources
Keynote talk
The development of new synchrotron light and neutron sources and the concomitant
increase in experimental complexity places challenging demands on detector
technologies. For any given instrument, combinations of one or more of; high count rate,
high spatial resolution, high temporal resolution and wide bandwidth are required. A
survey of some of the technologies currently being developed...

Oral Contribution
A wide range of area and linear detectors have been commissioned on the synchrotron X-ray beamlines operating at the Diamond Light Source in UK. In addition to mature technologies such as Image-Plates, CCD/scintillator detectors, Multi-Wire and Micro-Strip Gas detectors, more recent detectors based on semiconductor pixel/strip sensors coupled to CMOS read-out chips are also in use for routine...

Oral Contribution
A prototype X-ray imaging system, using the principle of tomographic energy dispersive diffraction imaging (TEDDI) has been developed at the University of Manchester's School of Materials. The non-destructive 3D imaging system makes use of a state of the art collimator array and a pixelated Si energy resolving detector. A proof of concept for the system has successfully been carried out using...

Detectors for Synchrotron Radiation and Spallation Neutron Sources
Oral Contribution
A novel ultra thin silicon detector called U3DTHIN has been designed and built for applications that range from neutral particle analyzers (NPA) used in Corpuscular Diagnostics of High Temperature Plasma to very low X-Ray spectroscopy. The main purpose of this detector is to provide a state-of-the-art solution for the upgrade of the current detector system of the NPAs at JET and also to pave...

Oral Contribution
Performance of a 4 cm long 32 pixel perforated diode neutron detector array is compared to an identical array of thin-film coated diodes. The perforated neutron detector design has been adapted to a 1-D pixel array capable of 120 micrometer spatial resolution and counting efficiency greater than 15%. Deep vertical trenches filled with ^6LiF provide outstanding improvement in efficiency over...

Detectors for Synchrotron Radiation and Spallation Neutron Sources
Oral Contribution
We report on progress made on the Aberystwyth University Electron Counting Detector array since the last PSD conference. A new detector with 1,536 pixels across an active area of 38mm x 5mm is presented. Also presented are applications of the existing detector in photoelectron spectroscopy, showing how the improvement in detection technology enables fresh insights into the fabrication of...

Oral Contribution
This paper presents the results of a trade study which looks at current and future requirements for detectors in coherent x-ray diffractive imaging. Several technologies are assessed against criteria, and observations about the challenges to soft x-ray detector science are discussed.
