fast_ring when having harmonic cavities in the lattice about at HOT 4 CLOSED

Hi @TeresiaOlsson ,
I've had similar comment from another user, most likely the same issue.
Could you please send me your script by email? I'll take a look.

Normally, get_timelag_fromU0 should be find a solution with multiple RF systems

Thank you :)

I have attached my files. The script is super simple but I have some parts at the end of the lattice file which maybe could be the cause.

    # Turn cavity and radiation on
    ring.enable_6d()
    
    # Set cavpts to point to main cavities
    ring.cavpts = ring.get_uint32_index('CAV*')
    
    # Set only main cavity phases
    ring.set_cavity_phase(cavpts=ring.cavpts)
