Presentation
- Yue Hao provided a brief update on the status of the EIC Virtual Accelerator, tentatively named EICVIBE (EIC Virtual Beam Environment). The lattice can be imported from the MAD-X design and follows the general structure of the ongoing PALS standard. Implementation using XSuite is currently in progress.
- Dr. Will Bergan reported on the design features, error analysis, and tracking results of the Rapid Cycling Synchrotron (RCS) for the EIC.
Discussions
- Jean-Luc commented on the generalization of virtual accelerator development. While the current work is machine-independent, the broader community need for virtual accelerators—particularly in the context of the machine learning era and digital twin roadmaps—remains insufficiently defined.
- Giovanni noted that machine-readable YAML output may present performance issues for online modeling. EICVIBE plans to connect directly with simulation engines in Python, reserving ASCII output solely for recording purposes.
- Georg, Yongjun, and Scott discussed the spin performance and nonlinear dynamics challenges of the RCS, particularly the sawtooth effect at 18 GeV due to synchrotron radiation. It remains unclear whether a ramping setup of the correctors can resolve this issue. Large orbit corrections could significantly reduce the dynamic aperture. While there appears to be no immediate need for a feed-forward algorithm during the ramp, ramping strategies may need to be refined based on data from previous cycles.
