Description
Challenging requirements are set for the FCC extraction septum magnets.
A scaled up LHC-like beam dump system or a massless architecture are not applicable in terms of maximum field, space reservation and power consumption.
The truncated cosine-theta septa configuration with a target field of 4 T has been proposed to address these requirements maintaining the reliability and availability of the extraction line, The study so far addressed magnetic performance of the magnet cross section such as the magnetic field, the field quality, and estimates for the leak field.
This contribution will additionally present the engineering design concept and provide a first look into the challenges associated with taking the 2D concept to the three-dimensional design.
