Nothing new here
So it seems science has beaten us to the punch once again. Remember last week’s optimistic story on how you can make better use of your (measurement) time? Turns out it has been done (at least once) before. The year was 1993, the authors were M. Steinhart and J. Pleštil, and they did the same [...]
Making better use of your time: optimizing measurement time
Often, especially when measuring on big facilities, you are given a limited amount of time. So when it comes to measuring the sample and the background, this limited time has to be divided between a measurement of the sample, and a measurement of the background. Normally, one would spend about 50% of the time on [...]
A compact pneumatic fibre tensile stage – publication
It is with pleasure that I can announce the publication of another fibre-related work, right here (The electronic reprint will be made available after December on this site). [edit: now available from this page] This tensile stage was the result of me not wanting to install a massive Instron stage at a beamline, nor did I [...]
Live FT video
A demonstration of the live Fourier Transform showing scattering patterns can be seen here:
More Youtube videos
So, I could not do what I promised last time, the Monte-Carlo fitting works on perfect simulated scattering patterns but is as of yet unable to deal with the addition of a flat background. So I will have to take a raincheck. In the mean time, I have made two videos (part 1 and part [...]
“Perfect” 1D pattern generation software.
I have written some small, simple bits of Matlab software that can generate scattering patterns in the range you request for polydisperse, dilute spheres or ellipsoids. While nothing new per se, this implementation is guaranteed to produce correct scattering patterns irrespective of the width of the distribution. Allow me to quickly explain. The normal way [...]
