OK looks like something is broken, using the test KHI (positrons/electron) and changing the drift to z-direction instead of x-direction is showing different images. `lds_energy.period 10 --e_energy.period 10 --e_energy.filter all...

I was going back with my KHI-z direction test case until 18th Jan 2022 https://github.com/ComputationalRadiationPhysics/picongpu/tree/e48017d498ef9f1645b484ac1678fabc9bf36786 and have everywhere the some issue that changing the drift into z-direction produces wrong results.

@PrometheusPi and me performed some more checks with the dev branch. # default KHI pos/el drift in X step 600  # same as default but drift in Z...

I switched back to a branch where we still had EsirkepovNative and FieldInterpolatin (no coordinate shift for the field interpolation) native in our code. `git checkout ce7aa8ff91f22777dd56d901f9c01d3395359486` The results are...

> @psychocoderHPC I believe the openPMD SST implementation uses ADIOS2 to format the data. I should have included that in my last post. Kim Could you please open an issue...

offline discussed with @PrometheusPi two weeks ago. Maybe we can trigger the start of the KHI differently and not via numerical effects to become a more reliable setup.

For the radiation mask changing this https://github.com/ComputationalRadiationPhysics/picongpu/blob/454a28efe6a6eb0fa1e0e97031ef2569a1ad313b/include/picongpu/param/speciesAttributes.param#L121 to `uint32_t` could work too. I have not tested it but if the compiler is not saying anything about the implicit conversion within...

Looks like there are some temporary files in the commit e.g. `#validate.sh#`, ... Do we need the h5 files in the PR?
