	The focusing of X-ray nanoprobe at TPS relay upon the special designed Montel mirrors and its adjustment holder. The holder includes two major parts: (1) fundamental-position alignment part and (2) relative-position adjustment part. The fundamental-position alignment part has the ability to adjust the two mirrors together in 6 DOF., such as X, Y, Z, pitch, roll, and yaw. These translation stages have several-tens mm travel range and nm resolution, while the rotational stages have 40 mrad azimuthal angular range and 0.1~0.01 µrad resolution. The relative-position adjustment part can further adjust the two mirrors to minimize the focal spot. During the pre-alignment process, one of the mirrors can be manual adjusted by micrometer heads in three translation directions with several mm travel range and micro-meters resolution. These micrometer heads also provide this mirror three rotational degree of freedoms with sub-mrad resolution. For the further alignment in vacuum, the additional four piezo-motor actuators can precisely adjust the other Montel mirror in the Y and Z direction with several nm resolution, and its pitch and roll with 1 urad and 0.05 urad resolution, respectively.

TUPE16	Design of A Leaf Spring Bender for Double Laue Crystal Monochromator at SSRF	ion, SRF, synchrotron, optics	198
	H.L. Qin, K. Yang SSRF, Shanghai, People’s Republic of China L. Jin, H. Zhang, W. Zhu SINAP, Shanghai, People’s Republic of China
	A leaf spring bender geometry for water-cooled double Laue crystal monochromator (DLM) is presented. The DLM will be employed to acquire high energy mono-chromatic X-ray (60keV to 120keV) on the ultra-hard applications beamline at SSRF. A compact bending mechanism is designed in order to get horizontally fo-cused high energy monochromatic X-ray as small as 0.5mm. The bender applies a piece of thin asymmetric crystal and a pair of leaf springs which push the crystal to a sagittally bent radius as small as 1 meter by a pair of symmetry moments. An optimized crystal geometry is achieved by taking into account the meridional and sagit-tal bendings coupled and defined by the anisotropic elas-ticity of the asymmetric crystal. Furthermore, thermal slope error and structural stress of the bent crystal are analyzed by finite element method (FEA).

WEPE26	Upgrade the Beamline PF-AR NW14A for the High-Repetition-Rate X-Ray Pump-Probe Experiments	ion, laser, experiment, optics	351
	S. Nozawa KEK, Ibaraki, Japan
	We report the upgrade of the x-ray pump probe system to high repetition rate at the beamline PF-AR NW14A. A 400 fs high-repetition rate fiber laser system (Amplitude, Tangerine) was newly installed. The fiber laser system, which is operated at 1030 nm fundamental wavelength, is capable of reaching up to 0.1 mJ pulse with a repetition rate of 400 kHz. A higher harmonic generation system enlarges the spectral range from UV to mid-infrared. To increase the laser power density at a sample position, the x-ray was additionally focused by a polycapillary lens (Polycapillary Optics, XOS). The synchronization of X-ray and laser pulses is based on the RF master clock of the storage ring. The delay between the laser and the X-ray is controlled by changing the emission timing of the laser with a Trigger & Clock Delay Module (84DgR5CO1, CANDOX). The high repetition rate system increases experimental efficiency 400 times.

WEPE36	Design, Construction and Commissioning of Two Highly Integrated Experimental Stations for Micro-Focusing Macromolecular Crystallography Beamlines at NSLS-II	ion, experiment, synchrotron, diagnostics	363

	Funding: This work is supported by the US National Institutes of Health and the US Department of Energy. We present the final engineering design and first commissioning results of two highly integrated experimental stations for the micro-focusing (FMX) and the highly automated (AMX) MX beamlines at the NSLS-II. These beamlines will support a broad range of biomedical structure determination methods. The experimental stations are designed and fabricated in-house to meet the challenging requirements resulting from the small beam size of 1 µm and the extremely short working distance of only 190 mm from the beam exit window to the FMX focal spot. The compact beam conditioning unit contains, within 140 mm, a beam position monitor, an attenuator, primary slits, an intensity monitor, a sub-millisecond shutter, and secondary slits. The diffractometers consist of an interchangeable dual axis air bearing-based goniometers with a target sphere of confusion of 100 nm, an on-axis microscope, an x-ray fluorescence detector and dynamic beam shaping slits. The end stations are integrated in a compact space on a granite machine bed with high modularity for future upgrades and extensions. Real-time autonomous robotic systems are being implemented for high through-put cryogenic sample handling.

FRBA02	The Nanobender: A New X-Ray Mirror Bender With Nanometer Figure Correction	ion, optics, controls, vacuum	413

	Over time X-Ray mirrors are demanded for better focusing, closer to sample refocusing, spot size as well as better beam uniformity at sample position. Based on the experience of ALBA Phase I beam lines a new alter-native design of a mirror bender* is proposed. The system includes two main functionalities: the mirror bender mechanism and mirror figure error correc-tion. Both mechanisms are based on the introduction of a force constrain on the mirror surface instead of a geometrical one. As being based on a force mechanism they could reach high resolution and especially for the correctors which can achieve nanometre resolution. The correctors are designed to provide high force stability in the mirror side, eliminating the crosstalk between bending and figure correction, and minimizing the sensitivity to drifts. With such controlled deformation of the mirror substrate it is possible to obtain the desired surface figure not only to correct mirror figure errors but also to adapt it to the incident wavefront, thus becoming adaptive system. The mechanical solutions are presented which are able to correct mirror surfaces with a resolution of 1 nm reaching slope errors below 100 nrad. * Patent Registered
