## Action Items

***Dominik***
* Finish review of grid3 [PR 981](https://github.com/PlasmaPy/PlasmaPy/pull/981)

## Minutes

* `m`, `q` arrays for particles - inefficient memory wise, if there are not too many species it's better to have a few `Species` class instances and iterate over those
* [Peter] outlined his scheme for Synthetic Proton Radiography
* Peter has a neat image in his presentation that explains the geometry of the whole thing; we should make sure it lands in the module's documentation
* take a close look at monte carlo angle initialization
* look at `self.x = np.outer...`
* think about better ways of tracking progress (tqdm)
* look at `x = ...; boris push; self.x = x` part
* synthetic_radiograph has a `null` argument (if True, compute histogram as if there was no grid); this **desperately** needs a better name
* [PR 895](https://github.com/PlasmaPy/PlasmaPy/pull/895): Proton Radiography is ready for a comprehensive review
* [PR 981](https://github.com/PlasmaPy/PlasmaPy/pull/981): Grids #3 needs to be merged first though
