Dear Leszek, All,

I want to remind you the steal of the backward HCal cannot be magnetic steal it needs to be stainless steal, so the fringe fields are correctly mitigated and the forces on the magnet are well blanced, so the change below is in correct as the lfHCal steel is magnetic.

Thanks Elke

Dear Colleagues

I prepared the configurations to test and optimize in this branch:

https://github.com/eic/epic/tree/negative-HCal-dev

Updates include switching from StainlessSteel -> Steel235 (same as LFHCAL). More description is here (added to links collection document)

https://docs.google.com/document/d/1i-5gqpS0KCXaxNDYvr4c0Ye8lKtaU0_1jiYp90TtqqA/edit?usp=sharing

We can in principle test more if you have other ideas. The list is already long, but we can pick the most important ones. Feel free to let me know.

Best regards, Leszek
