Schematic drawing of the soft matter CDI/XPCS setup of EH1. The setup is very similar to the standard CDI/XPCS setup in EH2. It is mounted on a 5-axis optical table from IDT. In front of the sample position, it features a pair of slit from JJ X-Ray (IB-C30-HV). These slits are ~700mm apart. The first slit defines the size of the X-ray beam and the second slit acts as a guard to suppress most of the slit scattering of the first slit. Between the slits, an in-vacuum (retractable) monitor unit is installed. The sample chamber is based on a DN100 (6" flange OD) UHV cube. The cube is mounted on a 4-axis Huber tower (X, Y, Z and RZ). The cube is fully vacuum integrated using DN (2.75" flange OD) bellows along the X-ray beam direction.
Multiple different sample inserts have been developed to be housed in the sample chamber (transmission and reflection setups, which are listed under EH2/Standard Setup/Sample Inserts). The sample position is followed by a DN100 (6" flange OD) 6-way cross. This 6-way cross allows e.g. to mount in-vacuum detector (e.g. diodes) as well as a vacuum pumping system. The last piece of the sample environment is a DN100 gatevalve before the scattered signal is transported to the end of the hutch in a 4" ID tube. There the tube diameter increases to 8" ID and the beam transport continues to the detector stage in the 2nd experimental hutch. By using a detector position at the end of EH2, a sample-to-detector distance of ~21.3 m is possible.
The setup is modular and it is envisioned that components can be removed from the IDT 5-axis table to make room for more complicated experimental setups. The optical table is equipped with a 1.50x1.00m<sup>2</sup> breadboard (mounting holes are M6 on a 25x25mm<sup>2</sup> grid). All optical tables at P10 are designed to have a 600mm distance between X-ray beam and table top surface.
