Novel applications of X-rays in non-destructive testing

IEE Colloquium on NDT 1992: Non-Destructive Testing in the Single European Market, 1992

Two types of X-ray scatter imaging are dealt with: Compton scatter imaging; and coherent X-ray scatter imaging. Two innovations in the areas of X-ray production and detection are also outlined-fluorescent X-ray production and a multisegment energy-dispersive X-ray detector.<<ETX>>

Large area, low capacitance Si(Li) detectors for low noise, high rate X-ray applications

IEEE Conference on Nuclear Science Symposium and Medical Imaging, 1992

Summary form only. Large-area, single-element Si(Li) detectors have been fabricated using a novel geometry which yields detectors with reduced capacitance and hence reduced noise at short amplifier shaping times. A typical 6-mm-thick device with an active area of 175 mm/sup 2/ has a capacitance of 0.5 pF for a conventional planar device with equivalent thickness and area. These low-capacitance detectors, ...


Evaluation of CdZnTe detectors for soft X-Ray applications

IEEE Transactions on Nuclear Science, 1994

High resistivity CdZnTe is a very promising material for X-ray detection at room temperature or slightly below. Cooling a Cd/sub 0.8/Zn/sub 0.2/Te crystal down to -30/spl deg/C reduces the leakage current to the picoamp level, which enables the use of low-noise pulsed optical feedback instead of noisier resistive feedback preamplifiers. Also, longer shaping time constants at the linear amplifier can ...

We also covered large a-Si thin-film transistor (TFT)-plates with PbO. Imaging results from a large detector with an active area of 18 cm /spl times/ 20 cm are presented. The detector has 960 /spl times/ 1080 pixels with a pixel pitch of 184 /spl mu/m. The modulation transfer function at the Nyquist frequency of 2.72 linepairs/mm is 50%. Finally, a full size X-ray image is presented.

  • Large area, low capacitance Si(Li) detectors for low noise, high rate X-ray applications

    Summary form only. Large-area, single-element Si(Li) detectors have been fabricated using a novel geometry which yields detectors with reduced capacitance and hence reduced noise at short amplifier shaping times. A typical 6-mm-thick device with an active area of 175 mm/sup 2/ has a capacitance of 0.5 pF for a conventional planar device with equivalent thickness and area. These low-capacitance detectors, in conjunction with low- capacitance FETs, will result in spectrometers capable of running at very high count rates while still maintaining excellent energy resolution. The spectral response of the low capacitance detectors to a wide range of X-ray energies at 77 K is comparable to that of typical state-of-the-art conventional Si(Li) devices. The spectral response to 2-60 keV X-rays was investigated.<<ETX>>

  • Evaluation of CdZnTe detectors for soft X-Ray applications

    High resistivity CdZnTe is a very promising material for X-ray detection at room temperature or slightly below. Cooling a Cd/sub 0.8/Zn/sub 0.2/Te crystal down to -30/spl deg/C reduces the leakage current to the picoamp level, which enables the use of low-noise pulsed optical feedback instead of noisier resistive feedback preamplifiers. Also, longer shaping time constants at the linear amplifier can be used for the optimum resolution. We have obtained resolutions of 240 eV (FWHM) for the 5.9-keV /sup 55/Fe line at -40/spl deg/C and of 282 eV at -30/spl deg/C. The Fano factor for the material at -40/spl deg/C was calculated to be 0.14. These results compare well with the results obtained with peltier-cooled HgI/sub 2/ detectors.<<ETX>>

  • Modeling clear phase-mask materials for sub-50 nm X-ray application

    Summary form only given. This paper presents a powerful modeling approach to the X-ray exposure operating space of a silicon nitride clear phase-shifter mask to produce sub-50 nm features. Although silicon nitride was examined, the approach can be used to model many other materials including Si, metals, and oxides, including complex shapes. Because this type of mask relies on both diffraction and phase shifting, the four factors, absorber thickness, absorber wall slope, gap, and CD were identified as critical to the resulting intensity profile. By first developing a central composite experimental design, we then used a wavefront modeling toolset to calculate intensity and linewidth responses for each of the response surface cells. Excellent second-order models were fit to the data for each of the responses.

  • Ultrafast lasers and X-ray applications

    Summary form only given. The rapid evolution of femtosecond laser technology has led to the generation of multiterawatt optical pulses at multi-Hertz repetition rates with pulse durations as short as 16 fs. The combination of high repetition and high peak power lends itself naturally to the generation of high fluxes of energetic particles and photons. Furthermore, X-rays generated with these pulses can have pulse durations which are several orders of magnitude shorter than the best synchrotron sources currently available. More importantly their time-scale (1 ps to <100 fs) is commensurate with that of many interesting physical phenomena including: the making and breaking of chemical bonds, the expansion of instantaneously heated lattices, optical phonon generation and propagation of laser induced shocks, etc. In this presentation, the development of 10-fs-range laser technology and ultrafast X-ray sources and applications will be presented. With these technologies it has been possible to generate picosecond X-ray movies of laser heated crystalline materials which show for the first time the propagation of coherent acoustic phonons into bulk material with milliangstrom strain resolution and picosecond temporal resolution. Extensions and possible future applications and sources will be outlined.

  • Image presentations for spinal kinematic analysis using digital videofluoroscopy

    The investigation of spinal mechanics in injuries and other painful conditions is frustrated by the difficulty of measuring the kinematics between individual segments. Problems associated with current methods of measurement include the radiation dosage required, the limited accuracy obtainable and the inherent labour-intensive nature of the numerical procedures. The authors have developed a technique for overcoming these problems using digital image processing of spine motion sequences obtained from low-dose X-rays using an image intensifier. A study of the prospects for using various image processing algorithms to improve the accuracy of measurements of the kinematics of the spine from videofluoroscopic image sequences is described.<<ETX>>

  • Bone movement analysis from computer processing of X-ray cinematic video images

    A method for the analysis of motion of the human spine from X-ray cinematic video images is outlined. A simple high speed algorithm tracks four points placed by an operator to outline vertebrae of interest on the middle image in the sequence. From the co-ordinates of the tracked points various types of vertebral motion are computed. Motion signatures for patients with known spinal conditions clearly show that individual vertebrae do not move smoothly, but proceed in an erratic fashion as the vertebrae jam and then release.<<ETX>>

  • Recent Advances in X-Ray Detection Technology

    A review is presented of recent developments in x-ray photon detectors and in the associated detector electronics. The first portion of the paper is devoted to a survey of the presently available physical inforrnation on the "intrinsic" resolution of silicon and germanium radiation detectors, proportional counters and NaI(Tl) scintillation crystals. Semiconductor detectors suitable for x-ray applications and low noise electronics are then analyzed in some detail. Discussions follow on scintillation detectors, proportional counters, and "external" photoelectric detectors. Recent spectral achievements and interesting applications are illustrated.
