EBSL8 Overview

EBLS8 is the upgrade project for ID29. It consists in the construction and commissioning of a new ID29 dedicated to Serial Macromolecular Crystallography experiments. The new beamline will provide an extremely high flux density over a wide energy range. Single diffraction images will be collected from micro-crystals at room temperature in a short exposure time, opening new perspectives for time resolved studies.

ID29 Beamline overview.

Two new endstations, EH1 and Eh2,  are being built in the Chartreuse Hall extension, at more than 100 meters from the source.
The new beamline will deliver a photon flux density up to 1016 ph/s/µm2 in a 0.5 x 0.5 µm2 at the sample position.

EH1 endstation is optimised for serial crystallography experiments on fixed target supports and viscous extruders, while EH2 is dedicated to development and prototyping of new methods.

Overview of the experimental hutches, control cabin and sample preparation lab.

The beamline will be equipped with its own sample preparation laboratory with direct access to EH1 and a data analysis room where data can be processed either on-line or off-line.

The new source

The new Extremely Brilliant Source permits to dramatically reduce the horizontal emittance and increase the photon flux delivered to the sample

The initial commissioning will be performed with the current undulator source (an in-vacuum U21 and an in-air U35), but future upgrade of the source considers the use of cryogenic permanent magnet undulators (CPMU).

Flux with the different sources currently available and under consideration for the future.

Monochromator

The monochromator system is using a double multilayer mirrors system. The presence of different coatings will allow the rapid change of energy and bandwidth.

Chopper system

A major component of the new beamline is the novel design of a chopper system that runs synchronously with the storage ring clock. Due to the high flux density a chopper is required to produce a pulsed X-ray with exposure time in the micro-to-millisecond time range.

Detector

Due to the extremely high photon flux ID29 will be equipped with a new generation of integrating detector designed for experiments at Free Electron Laser: the Jungfrau 4M  that combines single photon sensitivity to a dynamic range of four order of magnitudes.
