Description
The future PETRA IV synchrotron radiation facility at DESY, Hamburg will be a 4th generation light source in the 2.3km long PETRA tunnel, with first light in 2032. It comprises 8 straight sections and 8 arcs with 288 girders and space for 72 insertions.
The hybrid 6 bend achromat accelerator lattice aims for as much periodicity as possible to maximise symmetry, which is beneficial for beam dynamics, and minimise cell design variants. However, straight sections each fulfilling differing functions such as injection, rf acceleration or photon generation, more than a dozen variants of insertion devices, and differing tunnel cross sections introduce substantial variability of girders, cells, and arcs, increasing the engineering effort.
We have set up an engineering process, supported by a set of automated tools, that establishes a rapid, reliable translation of the lattice to the positions of all components that act on the beam. More than 6000 individual beamline elements are positioned in this way.As part of the process, we analyse girder variants to minimise the number of different mechanical designs for magnets, vacuum, and other systems, and to facilitate logistics processes.A managed change process ensures that lattice updates are systematically propagated to the engineering design.
