چکیده
LLE Review, Volume 152 184 Introduction The performance of inertial confinement implosions on OMEGA is potentially limited by the production of hot electrons.1 The hard x-ray image-plate (HXIP) diagnostic2 is used to determine the energy distribution of the hot electrons by estimating the spectrum of the x rays that are generated through bremsstrahlung with the target. Simulations and data from this diagnostic agree with a bi-Maxwellian shape for the total time-integrated hot-electron spectrum, which for low-Z targets generates an x-ray energy spectrum that is approximately the sum of two exponentials.3

Spatial distribution of electron cloud footprints from microchannel plates: Measurements and modeling
The measurements of the electron cloud footprints produced by a stack of microchannel plates ~MCPs! as a function of gain, MCP-to-readout distance and accelerating electric field are presented. To investigate the charge footprint variation, we introduce a ballistic model of the charge cloud propagation based on the energy and angular distribution at the MCP output. We also simulate the Coulomb ...
متن کاملDesigning and developing an in-house CCD based optical CT scanner for gel dosimetry
Introduction: Measurement of the complex 3D radiation dose distribution created with advanced radiotherapy techniques such as IMRT and SRS became very important. Polymer gel dosimetry (PGD) is proposed method to recording this dose distribution. MRI, X-ray CT, ultrasound, spectrophotometry and optical CT scanners can be used for readout of Polymer gel dosimeters. Although MRI i...
متن کاملUbiquitous Creation of Bas-Relief Surfaces with Depth-of-Field Effects Using Smartphones
This paper describes a new method to automatically generate digital bas-reliefs with depth-of-field effects from general scenes. Most previous methods for bas-relief generation take input in the form of 3D models. However, obtaining 3D models of real scenes or objects is often difficult, inaccurate, and time-consuming. From this motivation, we developed a method that takes as input a set of pho...
متن کاملAnalytical Solution for Sound Radiation of Vibrating Circular Plates coupled with Piezo-electric Layers
In the present study, the classical plate theory (CPT) was used to study sound radiation of forced vibrating thin circular plates coupled with piezoelectric layers using simply supported and clamped boundary conditions. The novelty of the study consists of an exact closed-form solution that was developed without any use of approximation. Piezoelectric, electrical potential loaded in the transve...
متن کاملA New CMOS Image Sensor with Pixel-Shared Design and Split-Path Readout Circuit
In this paper, a new CMOS active pixel sensor (APS) of 128×128 resolution is proposed for high quantum efficiency. The presented CMOS image sensor can operate at the power supply of 3.3V, and use both a new pixel-shared structure and split-path readout direction. This new method has the advantage that the number of transistors in each pixel is reduced to increase the fill factor by enlarging th...
