Most of the building services in E5 are provided through hubs with unified connection panels. The building services provide HVAC and lights as well as several distributed utilities for specific usage, such as primary vacuum (backing and rough), de-mineralized cooling water, compressed, clean, dry air, gaseous nitrogen at room temperature, communication networks, drainage, and exhalation exhaust.

The large size of this experimental hall (about 50m extendable up to 110m for the future use of the 10PW kilo-Joule class laser) enables the use of very long focal lengths for laser-matter interaction and allows for various possibilities such as testing a multi-stage electron acceleration approach and, most important, the use of magnetic undulators for the future perspective of generating X-ray radiation in the so-called XFEL scheme.

The E5 experimental hall covers a wide range of user needs based on the LWFA method. The LUX beam line is dedicated to users interested in the irradiation of various samples through the most advanced techniques; the HELL platform is a flexible experimental area mainly dedicated to users who want to test innovative concepts or simply to use the most advanced technologies for accelerating electrons by lasers at multi-GeV level.

HELL Experiment

The HELL platform is located in the southern part of experimental hall 5 (E5). The beam path is adapted to accommodate two laser beams simultaneously: L3 and L4 (both at 1 PW power level), with L4 also available in a non-compressed version, coming from the eastern wall. The future use of the L2 (also 1 PW-class) laser beam is not excluded. The distribution for the L4 10PW will be available only in a late phase.

LUX Beamline

The Laser-driven Undulator X-ray source (LUX) beam line is aimed at providing users with few-nm and few-fs X-ray pulses, enabling samples to be studied within a highly interesting water window region and providing high contrast especially for biological samples. In addition, two auxiliary beams with pulse durations  of <30 fs and <7 fs (with ultrabroad spectrum) will be synchronized with the X-ray pulse with precision of a few fs, to enable excellent pump and probe experiments.

Electron acceleration driven by high peak power femtosecond lasers was theoretically predicted in 1979 by Tajima and Dawson [5]. The brilliant idea to use laser-driven plasma-waves was experimentally demonstrated more than a decade ago, and presently this technique is used on a daily basis in many laboratories worldwide.
