Pretty matplotlib pgf figures in Latex documents

4 minute read

Published:

In my experience adding matplotlib figures into Latex documents is not trivial at all, unless you are satisfied with a simple non-vector png. I will try to explain here how to export a figure into pgf, and how to include that in your tex file later. The usual disclamer is valid here: it works on my machine and I can’t guarantee that it will work on yours. As of now, I am using python 3.9 and matplotlib 3.4. After the tutorial you can expect some result as the one shown in the figure below. Read more

Making a 25ps resolution Time-to-Digital converter on an Artix-7 FPGA

1 minute read

I want to share a small project I did in which a 25 ps Time-to-Digital converter is implemented in an Artix-7 FPGA. The goal was to be able to measure tiny intervals between singals from two photomultiplier tubes. Finally, a fast digitizer was better suited for the job, but nevertheless the TDC works well and could be useful. Read more

Animated 3D plot in spherical coordinates with gnuplot

4 minute read

Published:

I am working on a physics experiment that involves muons that are stored in a magnetic field and are traveling along circular orbits. Their motion inside the magnetic field is quite complex and involves oscillations with different periods – essentially they are like a spinning top, but instead of precessing around only one axis, they can precess around three.
