Fig.1 Schematic layout of the mirror chamber with the inclined nipple COOLING AND TEMPERATURE MONITORING The total power on the first optical element will be 13.5 W. Of this total power roughly 3 W will be absorbed on the mirror due to the mirror reflectivity. Nevertheless, it is recommendable that a soft mirror water cooling system should be adopted. Copper plates could be placed side way the mirror and forced on it elastically. 200/300µm thickness In-foil could be inserted between the Copper plates and the mirror to improve the thermal conductivity. Copper tubes for water circulation have to be brazed on the Copper plates. Water connections are admitted in vacuum only if enclosed in guard vacuum devices. In alternative a cooling system by means copper braids could be considered. The cooling media will be demineralized water delivered from the main cooling system of the beamline. The inlet pressure is 0.6 MPa but the design and the production must ensure no leakage between air and vacuum and between air and water with a water working pressure of bzp@uj.edu.pl Page 6 of 55

Threads should comply to metric standard. All ion pumps shall be supported by support structures in a manner that allows the pumps to be removed without dismounting the chambers. All motor driven motions must be equipped with high duty limit switches and, where necessary, encoders. Use of carbon containing materials in vacuum should be reduced to minimum. The Contractor will mount and align mirrors in all three mirror units at Solaris after/during the Site Acceptance Tests. The installation and SAT of the three mirror chambers will be performed by the Contractor SUPPORT SYSTEM FOR MIRROR CHAMBERS To sustain the mirror vessels, a vibration-free and stiff supports must be provided.

Assuming 140mm distance between Horizontal Exit Slit and VES, the HES device will be placed at mm from the source and the x-ray beam at that distance (the beam is focalizing approximately 140 mm downstream HES) is a rectangle of 0.17 mm (H) x max 0.42 mm (V). The vertical beam dimension depends on the C ff constant used on the monochromator. HES mechanism have to define the horizontal beam dimension at the plane of the vertical slits. HES unit will be equipped with two horizontal Tungsten blades coated with UHV compatible fluorescent material YAG (e.g. P43) or YAG:Ce on the upstream side.

19 A cylinder placed longitudinally with a DN63CF for x-ray entrance and a DN63CFR (rotatable) for the beam exit. The vacuum chamber entrance and exit flanges axes will be aligned on a plane placed at 1320 mm from the nominal ground level (to be confirmed by Solaris in 4 weeks after contract signing). The flange to flange overall length could be 400 mm. The parameters related with external dimensions for the vertical exit slit chamber listed in the specification as well flange size for the slit mechanism should be considered as a conceptual one. In the same chamber downstream vertical blades the DN40CF flange for diagnostic mounted on vertical or horizontal stage should be provided. The distance from VES blades to the exit flange of the chamber should be minimized and keep as short as possible and should not exceed 300mm. The vacuum chamber would be connected to a support table by means three or four adjustable support feet. The support feet will allow the chamber to be 3D adjusted within ±10 mm with an accuracy 50 µm. The support feet must also allow rotating the whole chamber around its vertical axis within at least ±1 with a resolution of 50 µrad. There must be a reference surface to align the slit with a water-level on the outside. This surface must be parallel to the slit within ±50 µrad. Survey points for the height and longitudinal positions are required. The table and the chamber will be mounted on a linear slide that will allow finding the real vertical focal plane changing its position along the beam. The requested stroke is ±100 mm from the nominal position and two long welded bellows have to compensate the longitudinal chamber movement. A free vibration and stable granite girder has to support the linear slide and the chamber. The chamber will not be pumped directly. To reduce pumping impedance the upstream and the downstream flanges will be DN63CF and DN63CFR respectively, and the welded bellows will be DN63CF / DN63CFR, according to the rule that for each component, downstream flanges are always rotatable. Both bellows should be delivered by Contractor Cooling and temperature monitoring VES blades do not need of cooling system nor thermocouples. HES blades do not need of cooling system nor thermocouples (if chamber equipped also with HES mechanism) VACUUM General vacuum requirements The materials, manufacturing processes, components and handling operations should be compatible with UHV procedure. A final base pressure 5 x mbar with a 300 l/s ion pump after baking with a temperature that not exceed 150 C and a total Helium leak rate 2 x mbar l/s are required.

To sustain the VES chamber, a vibration-free and stiff granite support must be provided. 3D adjustment feet have to be provided with a lateral and vertical stroke of ±15mm and a resolution of 0.1 mm. The adjustment feet have to be placed in such a way a pitch, roll and yaw regulation of ±1 could be achievable.

Other solution can contain concrete/granite block mounted on a fixed metal plate allowing horizontal lateral adjustment of the concrete/granite block ±15mm with an accuracy 0.2mm. The vertical adjustment in the range ±10mm should be possible in means that base metal plate before of gluing should have possibility for vertical adjustment MOTORIZATION The stepper motors must be approved by Solaris for compatibility with the control system Tango and motor controllers IcePAP adopted in the Solaris.
