Main Question or Discussion Point

Hi,
i am doing a project course in masters. i need help regarding on X-ray Spectrum absorption by semiconductors. I am doing the simulations in XOP(X-ray oriented programs) software which is freeware at http://www.esrf.eu/UsersAndScience/Experiments/TBS/SciSoft/xop2.3 [Broken]. So, my doubt is when the spectrum of X-rays are absorbed by Silicon, GaAs and CaTe(candium telliride), i read the output wave form from the above software but i don't know reason for why we going for this type interactions and what is the result of this actions. what happend to X-ray sprectrum after. weather any reactions takes plave between the atoms of that materials. if so, give the explanation abt this.

thanks in advance....

Hi,
I guess that software is mainly designed for synchrotron science (to me it looks like a software for controlling beam quality). Not for analyzing and absorption phenomenon for semiconductor materials..

no there are ineer option to check the sprectrum like filtering with different materials and also some other options not related to my project

It is X-ray optics software and may not suit you.
It is for analysing the undulator or wiggler spectrum, etc..
And in ESRF generally semiconductors like silicon crystals are used for monochromatization of the beam (In Advanced photon source and DLS diamond crystals are used). So there may be some option in the software to try different semiconductors to check the resolution after monochromatization.. So absolutely not useful for you.

this is the project from last three years in my univ and all are doing in that software and also i have got old report from students but i cant copy the things from those data. so i need to know the things. if u downloaded the software means go to optics->mirrors and filters->in that choose last option -> it will open new window and ask for *set parameters*-> in that chose only one filter -> give material name(in my casr Si, GaAs, CdTe) what you want to filter and cilck show to visuailize the plot....now i wnat to know about the reponse what you will get after all the process as i said. what makes the difference between these filters and how should i explaine the result...please clear me out..

Hi,
I guess you want to try for your specific material.. May be the new version might have changed. So better ask you friends..
cheers

First you should be clear WHAT you want rather than trying to learn the code/software. If you want to analyze the X-ray absorption spectra, then clearly this is not the software for you. It seems more inclined towards the analysis of the beam itself and its characteristics. Though (from the screencasts) it seems that it CAN be used for the analysis of XAS, but it is not the best of the available options. If you could clearly mention WHAT you want, then someone can help you better.

For XAS,
Athena, Iffifit, Xcurve can be useful.

I dont want any suggestions about software or any thing related to software. i need to know abouy how the X-rays absorption will happen if you used semiconductors like Silicon, GaAs and CdTe as a filter. I need some explanation about these concepts.

Hi,
From your post (please see above) it seems that you are asking for some idea regarding the usage of the software XOP. Therefore, abhi2005singh and myself trying to give you some hints.
