Prof. Horácio Fernandes (University of Lisbon) - Brief course on Remote Controlled Laboratories

04 Apr 2019   17:30-19:00

Srdečně vás zveme na kurz Prof. Horácio Fernandes (University of Lisbon) - Brief course on Remote Controlled Laboratories: The Langmuir probe. Kurz se koná 4. 4. 2019 od 17.30 hodin v místnosti B009 (budova FJFI ČVUT v Praze, Břehová 7, Praha 1).

Short information:
This course is intended to provide to students all the knowledge in how to execute experiments in the e-lab laboratory and to use several techniques and software tools to analyse and process the acquired data.

It is expected that students will acquire skills in acquiring data from the e-lab Langmuir probe experiment and to understand how to interpret such data.

At the end of the practical course the students should know:
(i) Configure, run and acquire data from a remote experiment;
(ii) Handle data and do their data analysis;
(iii) Feel the didactic of remote experimentation;
(iv) Understand how a physic apparatus could be converted in a remote laboratory (live discussion);
(v) Adjust the best-fit characteristic to a Langmuir probe and extract main plasma parameters from it.

The course has a total duration of 1.5 hours and consist from a brief introduction to Langmuir probes (plasma Physics) followed by a practical live remote experimentation session. Students will be encouraged to use their own data analysis skills previously acquired. You can bring your laptop with your preferred data analysis tool-pack from Wolfram Mathematica to Python, otherwise, the computers will be provided.

Plasmas have different characteristics from other states of matter and many diagnostic tools have been developed in order to measure their parameters. This experiment allows the measurements of some of these characteristics using one of the simplest methods, an electrical probe, the Langmuir probe. It consists of a thin filament made of a conductive material placed inside the plasma, which either attracts or repels the electrons in the plasma in accordance with its polarization. Measuring the probe I-V characteristic (the relationship between the biasing voltage and the respective collected current), you can determine the electron temperature and density of the plasma.
