Modeling soft-error susceptibility for IP blocks

11th IEEE International On-Line Testing Symposium, 2005

As device geometries continue to shrink, single event upsets are becoming of concern to a wider spectrum of system designers. These "soft errors" can be a nuisance or catastrophic, depending on the application, but they must be understood and their effects budgeted for. Ultimately, experimental measurement is needed to quantify soft error rates, but after-the-fact measurement is too late to ...

  • A four-layer depth of interaction detector block for small animal PET

    We are now planning to develop a positron emission tomograph dedicated to small animals such as rats and mice which meets the demand for higher sensitivity. We propose a new depth of interaction (DOI) detector arrangement to obtain DOI information by using a four-layer detector with all the same crystal elements. In this DOI detector, we control the behavior of scintillation photons by inserting the reflectors between crystal elements so that the DOI information of four layers can be extracted from one two- dimensional (2D) position histogram made by Anger-type calculation. As a preliminary experiment, we measured crystal identification performance of the DOI detector which consists of four layers of a 16 /spl times/ 16 crystal array using Gd/sub 2/SiO/sub 5/ crystals with Ce concentration of 0.5 mol %. Each crystal is 1.42 mm /spl times/ 1.42 mm /spl times/ 4.5 mm. A crystal block is optically coupled to a 256-channel flat panel position sensitive photomultiplier tube whose opening area is 52.0 mm /spl times/ 52.0 mm. We obtained sufficient positioning performance for this four-layer DOI detector on the 2D position histogram. We concluded it would be a promising device to realize a small animal positron emission tomography scanner with high sensitivity and high resolution.

  • Modeling soft-error susceptibility for IP blocks

    As device geometries continue to shrink, single event upsets are becoming of concern to a wider spectrum of system designers. These "soft errors" can be a nuisance or catastrophic, depending on the application, but they must be understood and their effects budgeted for. Ultimately, experimental measurement is needed to quantify soft error rates, but after-the-fact measurement is too late to make changes. This paper shows a methodology that can be used to estimate the soft error properties of individual IP blocks by using a combination of critical charge calculations and experimental data.

  • Solving the attenuation problem in emission computed tomography using homomorphic filters

    An approach to the attenuation problem in positron emission computed tomography (PET) is discussed. The underlying idea of the method, in which a homomorphic system and an iterative convolution backprojection algorithm are employed, is described. The use of these two algorithms in the new algorithm is discussed. Results obtained with the algorithms are judged acceptable, with the reconstructed images of many different phantoms tested seeming to converge after several iterations.<<ETX>>

  • Radiative Electron Capture for F8+ and F9+ Ions in Collisions with a He Gas Target

    The x rays from the radiative electron capture (REC) to the projectile K-shell were investigated for F8+ and F9+ ions incident on the He target atoms in the projectile energy range from 15 to 40 MeV. The peak energies of the K-REC x-ray spectra were found to decrease linearly with a decrease of the projectile energies as expected and extrapolated to the correct ls binding energies at zero velocity. According to theory the distribution width, ΓREC, of the REC energies should be independent of the binding energy of electrons in the projectile ions. However, it is found that ΓREC for F8+ ions is systematically smaller by 20% than that for F9+ ions. The measured REC cross sections for F9+ ions are slightly larger than twice those for F8+ ions and the total REC cross sections for F8+ and F9+ ions were found to be more than three orders of magnitude smaller than the total electron capture cross sections and the capture cross sections into excited states.

  • Noise properties of simultaneous dual tracer PET imaging

    The Cramer-Rao lower bound (CRLB) for one dimensional dual PET imaging of equilibrated tracers was calculated. The CRLB gives us a fundamental limit on the variance one can obtain in simultaneous dual tracer PET imaging when the two tracers are separated based on their difference in tracer half-life. The CRLB depends on the acquisition time, the two tracer half-lives and the ratio of the initial activities of the two tracers. The dual tracer bounds were compared with the bounds found in the single tracer case. Convergence properties of a 2D dual tracer tomographic reconstruction were also investigated. The images were reconstructed using a parametric iterative reconstruction (PIR) algorithm and image quality was compared to the separate mono tracer ML-EM reconstructions. The PIR algorithm was found to recover the two components, however, convergence rates were slower than the mono tracer convergence rates, thus requiring more iterations to reach the same error level. The convergence rate improved drastically for increasing acquisition times. Our analysis can be extended to evaluate the limits of any number of tracer mixtures

  • Electron Capture from Inner Shells by Fully Stripped Ions

    Theories for electron capture from inner shells by fully stripped ions are compared with experiments for K-shell vacancy production, The recently developed theory goes beyond the Oppenheimer-Brinkman-Kramers (OBK) approximation since it accounts for the perturbed stationary-state (PSS) and relativistic (R) effects in the description of inner shells as well as for the Coulomb (C)-deflection of the projectile ions; at high velocities of these ions, the theory merges with the second Born approximation. Agreement with a vast amount of data is obtained without introduction of semiempirical scaling factors. The scheme of calculations, which are cast in terms of the OBK cross sections of Nikolaev3 only for convenience, is presented through a sample evaluation of electron capture cross sections.
