QUASR: the QUAsisymmetric Stellarator Repository

<p>This is a dataset of approximately 370,000 vacuum field stellarators along with the electromagnetic coils that generate them.&nbsp; They are optimized for quasiaxisymmetry and quasihelical symmetry.&nbsp; The devices in the database are available in a couple of formats (SIMSOPT, VMEC) useful to the stellarator community.&nbsp; The most current version of the data set can be visualized at quasr.flatironinstitute.org</p> <p>&nbsp;</p> <p>=============</p> <p>Version history</p> <p>=============</p> <p>v4 (September 6, 2024): QH devices added.</p> <p>v3 (April 8, 2024): typo fixed.</p> <p>typo in uploads v1, v2: the 'total_coil_length' and 'coil_length_per_hp' keys in dataframe should read 'total_coil_length_threshold' and ''coil_length_threshold_per_hp'', i.e., the maximum allowable coil length and maximum allowable coil length per half period, respectively.</p> <p>v2 (January 29, 2024): additional QA devices added.&nbsp;</p> <p>v1 (October 29, 2023): initial upload.&nbsp;&nbsp;</p>
