Cyclotron hard test fails #21

Open rodarima opened 4 years ago

The electron is moving in a larger orbit, with the biggest error, with the 10m radius test, is 0.00625m in the +X direction. The angular velocity is therefore slightly lower, so the hard check has an linear accumulation error.

The approximation given by Boris may introduce a delay in the gyroradius angle https://aip.scitation.org/doi/10.1063/1.5051077, thus leading to a larger radius.
