Motor controller madness – a tale as old as time

2023-11-29 Brian Pauw 3

A few weeks ago, at about the same time we were swapping around motor stages for grazing incidence experiments, my trusty self-built motor controller version […]

A scrap wafer mounted on our GI sample holder, held on with grease. The sample is tilted at the maximum angle to investigate stability.

A convenient grazing incidence (GI) sample holder

We’re just getting started with grazing incidence measurements on our MOUSE instrument. These measurements require mounting a sample (typically a wafer or glass slide), so […]

Those of you who have been around this blog a while, know that we have also been dabbling in laboratory automation (see, for example, this […]

Why most machine UIs are terrible for science and business, and one easy step to fix it! (it’s not what you think!)

My sincerest apologies to you for the most clickbait title ever. It had to be done because it integrates in a larger system of SEO […]

Unnecessary Grazing Incidence Traditions? (Not) putting the surface at the center of rotation

2023-09-05 Brian Pauw 1

I don’t have a whole lot of experience with Grazing Incidence (GI) geometry, indeed, I don’t have much at all. Now that we’re starting to […]

Not a lot of money.

Spending money on Bonse Hart Bling-Bling

[ed1: Progress on the Everything SAXS book has been good: a framework is now in place with chapters, the revision ID on the title page […]

SAXS Instrument runthrough

Video: The bits of a SAXS machine

2014-04-28 Brian Pauw 0

This week, I decided it’s time for another short video. Since I have never actually shown a SAXS machine, I thought it’d be of interest […]

A sample (blue) and background (green) measured on the slightly optimised Bonse Hart system. Scale is "symlog", meaning it is linear between 10e-3 and -10e-3 (hence the strange bump).

Tweaking the Ultra-SAXS machine

2014-01-20 Brian 2

It has been a very quiet four months (since this post) on the Bonse Hart front, as the generator was out of order (yes, again, […]

The Bonse Hart instrument works!

2013-08-12 Brian 3

Ok, so let’s start with the disclaimer: very initial results (fresh off the instrument, hence the delay), and the primary beam intensity is still very, […]

Taking the Bonse Hart instrument apart again…

2013-07-29 Brian 0

After a week trying to get a good reflection to come through the crystal — and failing —, it is time to take it apart, […]
