If not otherwise stated, all scripts have been tested using MAD-X \u003e 5.05.02.\n\n### Documentation\n\n- Each script directory contains a ``README``, outlining the basic functionality and notes on possible pitfalls.\n- Excessive use of comments in the MAD-X scripts itself is encouraged.\n- General documentation of the OMC Team is located at https://pylhc.github.io/.\n\n### Maintainability\n\n- The main scripts should be named ``job.madx`` and placed in an accordingly named directory in the directory tree.\n- Supporting files should be uploaded in the script directory. Links to external afs directories should be avoided as files might be modified there or removed.\n- Running with the minimum amount of unavoidable MAD-X errors is prefered.\n\n## Studies\n\n- *LHC* - The flagship collider of the 21st century\n    - *Coupling RDT Bump* - Creates closed coupling bumps in the LHC IR2 and Arc12. For Beam2, a model twiss for clockwise orientation is created and then tracking is performed using the correct counterclockwise sequence of Beam2.\n    - *Sextupole RDT Bump* - Creates closed sextupole RDT bump in Arc12.\n    - *Injectionenergy with misaligments and correction* - Realistic model of the LHC at injection energy with misaligments and nonlinear correction.\n    - *Kmod simulation* - Simulating K-Modulation in one Q1 quadrupole.\n    - *Tracking with ACD* - Setup for AC-dipole in LHC and subsequent tracking.\n    - *Model Creation with ACD* - Setup for twiss outputs taking in consideration the effect of AC dipoles.\n- *FODO Testlattice* - Small FODO lattice for benchmarking theories and scripts\n    - *Lattice Setup* - Setting up basic lattice and return twiss.\n    - *Phase Trombone* - Setting up basic lattice, match tunes via a phase trombone and return twiss.\n    - *Phase Error Propagation* - Setting up basic lattice, examine phase error under different boundary conditions\n- *PETRA3* - PETRA III, DESY's brilliant X-ray light source\n    - *Model Creation* - Creates model twiss files with AC-dipole and tune selection.\n\n## Authors\n\n* **pyLHC/OMC-Team** - *Working Group* - [pyLHC](https://github.com/orgs/pylhc/teams/omc-team)\n\n## License\n\nThis project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpylhc%2Fmess","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpylhc%2Fmess","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpylhc%2Fmess/lists"}
