Perl in the Physics Lab

Let's visit our university lab. We work on low-temperature nanophysics and transport spectroscopy, typically measuring current through experimental chip structures. That involves cooling and temperature control, dc voltage sources, multimeters, high-frequency sources, superconducting magnets, and a lot more fun equipment. A desktop computer controls the experiment and records and evaluates data.

Some people (like me) want to use Linux, some want to use Windows. Not everyone knows Perl, not everyone has equal programming skills, not everyone knows equally much about the measurement hardware. I'm going to present our solution for this, Lab::Measurement (see also ). We implement a layer structure of Perl modules, all the way from the hardware access and the implementation of device-specific command sets to high level measurement control with live plotting and metadata tracking. Current work focuses on a port of the entire stack to Moose, to simplify and improve the code.
