QUASR: the QUAsisymmetric Stellarator Repository

This is a dataset of approximately 370,000 vacuum field stellarators along with the electromagnetic coils that generate them. They are optimized for quasiaxisymmetry and quasihelical symmetry. The devices in the database are available in a couple of formats (SIMSOPT, VMEC) useful to the stellarator community. The most current version of the data set can be visualized at quasr.flatironinstitute.org ============= Version history ============= v4 (September 6, 2024): QH devices added. v3 (April 8, 2024): typo fixed. 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. v2 (January 29, 2024): additional QA devices added. v1 (October 29, 2023): initial upload.本数据集包含约37万个真空场仿星器及其配套的生成其磁场的电磁线圈。它们针对准轴对称（quasiaxisymmetry）与准螺旋对称（quasihelical symmetry）进行了优化。该数据库收录的装置可采用两种适配仿星器研究领域的格式（SIMSOPT、VMEC）进行使用。当前最新版本的数据集可于 quasr.flatironinstitute.org 进行可视化浏览。 ============= 版本更新历史 ============= v4（2024年9月6日）：新增准螺旋（QH）装置。 v3（2024年4月8日）：修正拼写错误。 第1、2版上传文件存在拼写疏漏：数据框中的'total_coil_length'与'coil_length_per_hp'字段应分别为'total_coil_length_threshold'与'coil_length_threshold_per_hp'，即分别指代最大允许线圈总长与每半周期最大允许线圈长度。 v2（2024年1月29日）：新增准轴对称（QA）装置。 v1（2023年10月29日）：首次上传发布。
