F5170-python

Programming exercises in Python for "Introduction to Plasma Physics" at Masaryk university

This repository is organized by mirroring Interactive Introduction to Plasma Physics. Part II: Hands-on exercises. You are encouraged to take a look at the original material to look for physical insight, context and pretty pictures. The code there is written in MATLAB. In this repository, you will find the code (in Python) needed to complete the exercises.

For instructions for installing Python and the Python package manager pip take a look at the wiki pages in this repository.

If you think you found an error or have a suggestion, please do not hesitate to email me at [email protected] or even better, create a github account and make an issue.

f5170-python's Issues

motion - add mag. moment formula

https://en.wikipedia.org/wiki/Magnetic_moment#Magnetic_field_of_a_magnetic_moment

Exercises are in a different document

wrong dataset/exercise in 4_Data

eV and K are probaby mixed up. also units on figure.

gradB drift

GradB drift from 3 is set up in a way that the drift is not comparable with theory. Set initial conditions differently or use different magnetic field

writing to file

Writing to file in a loop may be nontrivial. Add it to fundamentals or example scipt

variables needs comments about content

exercise 6.8 missing

version in czech

three-body reactions

In 6_Balance three reactants are used for two binary collisions.
What is the rate for a three-reactant reaction combined from two binary collisions with known rates?
Under what conditions is it possible to combine two reactions into one?

rate constants explanation

Commentary about rate constants is missing. Also effect of distribution function overlap with cross section -- maybe geometric interpretation.

Commentary about cross section is also missing in 4 and 5.

exercise 5.4 too easy

Exercise 5.4 is interesting by showing what computers can do, nonetheless it is not very challenging as a programming exercise

exercise 2 in 6-Balance is confusing and has the wrong implementation

nAr = p/(kB*Tg) - y[:,0]- 0.5*y[:,2]- y[:,1]

should be

nAr = p/(kB*Tg) - y[:,0]- 2*y[:,2]- y[:,1]

from argon conservation.

In the case of non-reacting gas, this would be:

nAr = p/(kB*Tg) - y[:,0]- y[:,2]- y[:,1]

because of partial pressures, which makes the exercise a bit confusing.

4 is too easy

update fundaments

2_Fundamentals contains instructions for matlab, and is missing some exercises in Python.

Example plots are missing

Exercises should have example plots shown
