For X-ray optics, OASYS integrates diverse strategies via the implementation of different simulation tools (e.g. ray-tracing and wave optics packages). It provides a language to make them communicate by sending and receiving encapsulated data[31]. OASYS itself is an empty container, while applica...
A semi-empirical formula allowing the extrapolation of the calibration curve towards higher energies. 2. Calibration by means of high energy gamma rays from (n,γ) or (p,γ) reactions produced in accelerators or nuclear reactors. These methods are time consuming, expensive and often inaccurate. ...
wherein the luminescent layer is doped with a guest fluorescent doping material and the guest fluorescent doping material for the luminescent layer comprises a compound represented by Formula II: wherein R1, R2 and R3 each independently represent a linear or branched aliphatic group having from 1 ...
The proposed focusing-optics concept presents a potential step toward realizing XFI with conventional X-ray tubes for high-resolution applications involving interesting NP formulations. Keywords: X-ray fluorescence imaging; nanoparticles; HOPG/HAPG optics; Geant4 Graphical Abstract ...
After optimizing it (remove all divisions and the normalize) you'd end up with the formula I have for sdTorus(). It's easier (2D instead of 3D) and also has this nice interpretation (for a donut in the XZ plane): 1. Imagine the torus with 0 thickness and radius t.x. It is ...
hence our reconstructed patterns will be smeared out. To quantify the smearing, in this chapter we derive the resolution formula for a realistic, finite-sized scattering pathway, as shown in Fig.7. The accuracy ofqis determined by the size of the source and the voxel, as well as the size...
Multilayer Optics Kohn’s multilayer formula is now implemented in Bmad. It matches the “golden standard,” Parratt’s recursion formula, and is an order of magnitude quicker. The next step will be to debug Laue geometry in Bmad, and begin simulating the proposed ...
Forum: Optics M Cathode Ray Tubes: Understanding the Role of Cathodes From my current understanding, a cathode is an electrode which has conventional current flowing OUT of it (or electrons flowing INTO it) while an anode had conventional current flowing INTO it (or electrons flowing OUT of...
Using a scattering approach to quantization, this allows a derivation of a trace formula for the density of states, see section 4. Then follows a discussion of the pure hemisphere in section 5 which can be solved exactly along with a comparison in section 6 with the previous general case. ...
