1 Mechanical Design of an Ultra-High-Vacuum Compatible Compact Hard X-ray Monochromator with Artificial Channel-Cut Crystal Mechanism D. Shu, S. Narayanan, and Alec Sandy Experimental Facilities Division, Advanced Photon Source, Argonne National Laboratory, Argonne, IL 60439, U.S.A. Abstract A compact ultra-high-vacuum (UHV)-compatible x-ray monochromator has been designed and constructed at the Advanced Photon Source (APS) 8-ID beamline for coherent small angle x-ray scattering applications [1]. The monochromator is designed for a small gap between the two crystals (~3 mm) which helps in maintaining a nearly constant spatial offset while changing energy with a single sine-bar mechanism. The sine-bar mechanism is driven by an UHV-compatible linear motion stage with HR-U piezoelectric servomotors from Nanomotion Incorporation. The piezo-electric motors operate under closed loop with encoder feedback to a resolution of 10 nm. An UHV-compatible artificial channel-cut crystal mechanism [2] was integrated in the monochromator to allow that the two independent crystals can be super polished to state-of-the-art for preserving the beam brilliance whereas the same is not feasible with a channel cut crystal. Mechanical designs for the UHV-compatible artificial channel-cut crystal mechanism and the sine-bar mechanism with piezoelectric servomotor drivers are presented in this paper.

2 INTRODUCTION Beamline 8-ID-I [1] at the Advanced Photon Source (APS) requires a doublebounce Ge(111) monochromator to produce a coherent beam with the appropriate longitudinal coherence for x-ray photon correlation spectroscopy (XPCS) measurements. The monochromator should be mechanically stable so that spurious monochromator motions do not corrupt the fluctuating scattered x-ray signal arising from the sample. Moreover, XPCS is a brilliance-limited technique so the monochromator must preserve the beam brilliance by having highly polished diffracting faces. Unfortunately, the latter has not proven possible with either the current 8-ID-I traditional channel-cut design or an enhanced Z-step channel-cut crystal [2]; they both produce spatially inhomogeneous (and statistically indistinguishable from each other) monochromatic beams. INTRODUCTION Specifically, Fig. 1(a) shows the monochromatic beam produced by our legacy monochromator measured 5- meters downstream of the monochromator via a Roper Scientific CoolSnap HQ pixels area detector and Zeiss tube-lens system that yields 0.7 micron-per-pixel resolution. Evidently, the beam incident on the collimating slits that select a coherent fraction of the monochromatic beam is already very non-uniform leading to decreased optical contrast and a decreased XPCS signal-to-noise ratio (SNR) [3]. Fig. 5. Old and new Ge(111) monochromatic beams measured with a As such, we embarked on a new artificial channel-cut monochromator design that CoolSnap HQ (0.6 µm/pixel) area detector. facilitates polishing of the diffracting faces while preserving and enhancing the mechanical stability provided by our current monochromator.

5 Monochromator Sine Bar Structure and Driver Detailed cross-sectional side and front views showing the mechanical and vacuum design of the artificial channel cut monochromator. In the center and right panels the pink x-ray beam is incident from the right and the monochromatic beam is transmitted to the left. Referring to this figure, a precision hollow shaft (2) supported by two sets of shaft bearings inside a precisely machined rigid housing permits stable angular rotation of the crystal by means of the sine-bar mechanism. The sine bar (6) is mounted to the shaft (2) with maximized rigidity, permitting the 236-mm-long sine bar to have a 13º rotation range. Using a hardened ruby ball (7) as a precision contact point, the sine-bar arm is driven by a commercial UHV-compatible ceramic-motor-driven linear positioning stage (8) that has 10 nanometer closed-loop linear resolution based on an UHV-compatible linear grating encoder on the stage [5], yielding high angular resolution (42 nrad, theoritically) of the artificial channel-cut assembly. The artificial channel-cut crystal mechanism (4) is attached to front of the sine bar, which is cradled with the high-stiffness precision shaft. The entire assembly, including the channel-cut crystal cage (see below), is contained in a compact UHV vacuum chamber (1) eliminating the use of bellows to transmit the motion and thereby any residual vacuum forces. Water cooling is provided by bellows-insulated cooling lines (3, 5). [8] Monochromator Sine Bar Structure and Driver
6 Monochromator Sine Bar Structure and Driver Achieving the mechanical and vacuum design requirements required incorporation of several novel UHV-compatible motion stages. Chief among them is an UHV-compatible linear slide assembly comprised of a precision slide from Alio Industries, piezoelectric actuators from Nanomotion, an encoder from Renishaw, and an ACS Motion SPiiPlus stand-alone Ethernet servo controller. The combination delivers exceptionally precise closed-loop positioning in vacuum over extended length scales and velocity ranges.

8 UHV-Compatible Artificial Channel-Cut Crystal Mechanism Monochromator Control System An important control requirement was ensuring that this new monochromator sine bar driver assembly could be seamlessly integrated into Beamline 8-ID s VME-based-EPICS beamline control system. This was completed by creation of an EPICS 3.14 device driver so that a standard EPICS motor record can communicate over Ethernet with ASCPL+ command sequences exposed by a socket layer hosted on the ACS Motion SPiiPlus motion controller. Aside from allowing us to integrate this motion into our control system, the Ethernet-based architecture permits ready access to specialized servo tuning, motion-profile-creation,, using ACS Motion s SPiiPlus MMI Windows based application without switching delicate cabling. [8]

Old and Fig. new a Ge(111) monochromatic beams Fig. measured b with a CoolSnap HQ (0.6 µm/pixel) area detector. Fig. b shows the Ge(111)-monochromatized beam (7.35 kev) produced by the new monochromator. Evidently, its transverse intensity profile is considerably more uniform than that produced by the traditional channel-cut monochromator previously installed in Beamline 8-ID-I (Fig. a). In particular, the variance of the recorded intensities in the center range X and Y < 67 microns is 50% less in Fig. (b) as compared to that in Fig. a. Moreover, the intensity in Fig. a varies rapidly over considerably smaller length scales versus that in Fig. b with negative implications for the stability of the overall set-up (since the smaller length scale (~ 25 micron) roughly corresponds in size to typical collimating apertures [1]). [8]
10 Test Results and Discussion In conclusion, we have designed and implemented an artificial channel cut monochromator to deliver stable, monochromatic and maximally brilliant x-ray beams to XPCS experiments performed at Beamline 8-ID-I. We expect that increased beam uniformity will contribute to enhanced measurement stability and to decreased x-ray-beam brilliance both of which will increase the SNR for XPCS measurements and, consequently, the range of sample dynamics that can be probed. Future commissioning activities will probe the effect of the horizontal-bounce mirror (see Table 1) on the intensity variation displayed in Fig. b. [8] Acknowledgments Many thanks to: M. Sprung, J.
