Thank you for your question. The X-ray source for laboratory total diffraction measurements is usually considered to be unpolarized, which is mostly true even when incident mirror optics are used such as in the Rigaku SmartLab and Synergy systems. Conceptually, you can think of an unpolarized X-ray source as being made up of an equal amount of X-rays polarized in two orthogonal directions. For reflection measurements, we usually think of one of the orthogonal directions as being normal to the sample surface and the other in the plane of the surface. In the same way that light is polarized on reflection from water, the X-ray polarized normal to the sample surface will be preferentially absorbed dependent on the diffraction angle and for diffraction angles of 90° 2θ will be completely absorbed. Simplistically, at 0 and 180° 2θ there is no preferential absorption, and the X-ray intensity will be 100%. While at 90° 2θ, the normal polarized X-rays are completely absorbed reducing the X-ray intensity to 50%. This gives a dip in the measured total diffraction intensity as a function of 2θ. This does not apply to synchrotron sources that are already plane polarized or when you use an incident beam monochromator with large Bragg angle.

i look forward to the day when scanning a cell and can see the atomic strucutre of the entire single cell organism and when not just a 3d model of it but that one can program algorthms to mimic each molecular interaciton to make it come alive inside the computer. perhaps some digital em radiation would emit from the simulaiton as some random digital noise.
Wow, the XtaLAB Synergy-ED electron diffractometer is mind-blowing! The level of simplicity and utility it offers for studying atomic and molecular structures is simply awe-inspiring. Science and technology continue to push boundaries. Excellent video explanation of the current outcomes!
Dear Juan Ignacio Tirado Castaño, Thank you so much for your enthusiastic message about the XtaLAB Synergy-ED electron diffractometer. Your appreciation for its simplicity and utility is truly motivating. Rigaku
Excelent presentation. Thank You! It would be great to make short demonstration video of new HSPA detector. "live from lab" kind of for interested, potential users(or lots of clear white papers/application notes).
@@bobburton3495 Hello, I just want to ask one more quick question. During the process of creating an empirical calibration with standard reference materials (for Thin film application), can I input the blank subtraction automatically? Or does it have be done manually?
Wonderful workshop!!!! I'm collecting micro-CT images of rabbit lung, but there is metal artifacts due to ECG cable. Can Dragonfly reduce metal artifacts? Thanks!!!
Happy birthday for Miniflex! It would be great to see more video demonstrations on the miniflex- like benefits of 2d detector, use of monochromator (how easy it is to switch it) etc. From the perspective of person searching for benchtop alternative/companion to large smartlab diffractometer for routine samples.
Hi, It would be great to see more video demonstrations on the miniflex- like benefits of 2d detector, use of monochromator (how easy it is to switch it) etc.
Hi! I have a question concerning creating the scale bars or setting the scale. Normally, we just know the pixel size (e.g., 5 - 8 um) that is used during micro-CT analysis. How can we create or set scale when we want to analyze micro-CT data by knowing just pixel size or voxel size from micro-CT analysis?
If you know the voxel size of your micro-CT scan, you can set the scale. Go to the "Analyze" menu and select "Set Scale..." When the Set Scale dialog appears, type in the size of the voxel, aspect ratio, and the unit. You can watch me do it in this video starting at 12:07.
The unit mass% is concentration and sometimes called weight/weight %, wt/wt% or simply %. It means the % concentration by weight rather than the % by volume like g/L. Mass% is g/100g. Another good way to say g/100g is 1 gram of the element per 100 grams of the sample.
@@anesmokhnache4629 Mass% is grams of element per every gram of sample. If you have more detailed questions, please email info@rigakuEDXRF.com to talk to a specialist.
This would have been much more useful, if you showed the different data gathered with the different detector setups. A 2D detector is fairly unique, I think, but you only show how to move hardware. It is the data, its geometric specificity, its sampling rate and sensitivity that make the difference. It is not ease of moving parts, but ease of doing different kinds of analysis. I really wanted to know more how you implemented MegaSamplePerSecond sampling rates and how you calibrate and handle that data. But it was just moving parts.
About a month ago I went through a week of CT training at a well known manufacturer. Being brand new to the industry it was a lot of information to absorb in one week and already forgot much of the material. This reinforced nearly all the basic concepts that I needed. Every scan is different and requires a different approach when creating a method/technique. The less I have to think about the basics the better. Thank you!
Thank you, Real Stonehead. We are now doing live workshops. I hope you will join us sometime! Here is the workshop info: events.rigaku.com/xct-workshop-series-2021.
Thank you, Don! The SiC/SiC sample was about 1 mm cube. We didn't apply phase contrast for the results shown here. It would definitely increase the contrast even further.
