Description
The strive towards lower emittance in 4th generation light sources often restricts the dynamic aperture and lifetime, creating challenges for injection efficiency and commissioning. Once a circulating beam is established, BPM calibration, BBA and other optics corrections can be applied. However, with a limited DA, it can be difficult to establish a circulating beam at the start of commissioning. To address this problem, we have developed a lattice design that allows for both low emittance optics (for standard user beam operation) and what we have called “commissioning optics” which is a set of lattice parameters that allows for larger dynamic aperture and Touschek Lifetime at the temporary cost of larger horizontal emittance.
