Construction and characterization of a short-period undulator for a laser-plasma driven light source — •Maximilian Trunk, Irene Dornmair, Christian Werle, Florian Holy, and Andreas R.

Laser-plasma accelerators provide high accelerating gradients and are therefore promising candidates as drivers for next generation brilliant light sources. The LUX experiment, developed and operated by the LUX junior research group at the University of Hamburg and situated at DESY, aims at producing spontaneous undulator radiation from laser-plasma generated electron beams. The BEAST II undulator is based on permanent magnets and is designed and built for in-vacuum operation in the lux beamline. It features an extremely short period length of 5 mm, a gap of 2 mm and consists of 100 periods. Already for an electron beam with a kinetic energy of 400 MeV, the produced X-ray radiation is expected to reach the water window with a wavelength of 4 nm. The contribution will cover the design, construction and manufacturing of the BEAST II undulator.
