The High-Dynamic Double-Crystal Monochromator (HD-DCM)*,** is an opto-mechatronic system with unique architecture, and deep paradigm changes as compared to traditional beamline monochromators. Aiming at unmatching scanning possibilities and positioning stability in vertical-bounce DCMs, it has been developed since 2015 for hard X-ray beamlines at Sirius Light Source at the Brazilian Synchrotron Light Laboratory (LNLS). Two units are currently operational at the MANACA (macromolecular crystallography) and the EMA (extreme conditions) undulator beamlines, whereas a model for extended scanning capabilities in the energy range between 3.1 to 43 keV, the so-called HD-DCM-Lite, is in advanced development stage for two new beamlines, namely: QUATI (quick absorption spectroscopy), with a bending-magnet source; and SAPUCAIA (small-angle scattering), with an undulator source. In this work, online commissioning and operating results of the HD-DCMs are presented with emphasis on: the 10 nrad RMS (1 Hz - 2.5 kHz) pitch-parallelism performance; energy calibration; energy-dependent beam motion at sample; and flyscan with monochromator-undulator synchronization, which is a well-known control challenge at beamlines. To conclude, the Sirius HD-DCM family prospects, including the HD-DCM-Lite, are discussed.

The performance of monochromator is crucial to the performance of a beamline, especially for a 4th genera-tion synchrotron light source. To find out the perfor-mance of the monochromator prototype built for the HEPS project, it was tested at a wiggler beamline of BSRF with water cooling. The cooling of the crystals was measured by rocking curve broadening at different energy and cooling seems to be not enough due to indium foils. The repeatability in 1 hour was about 0.1 eV. The energy drift in 9 hours after the beam hit the beam-line was 0.4 eV at the Cu K edge. The short-term stability was tested with synchrotron beam under various cooling condition, and results between 4.4 nrad to around 400 nrad were observed. In conclusion, some performances are satisfying, but further improvements should be carried out in the future.

  Scientific instruments and utility equipment during the operation of high radiation facilities such as the Advanced Photon Source at the Argonne National laboratory express a challenge to monitor. To solve this, we are developing a self-guided artificially intelligent robot that can allow us to take images to create a thermal and spatial 3D map of its surroundings while being self-driven or controlled remotely. The overall dimension of the robotic vehicle is 20 in length, 7 in width, and 10 in height, which carries a depth perception camera to guide the path, an IR camera for thermography, as well as a cluster of sensors to assist in navigation and measure temperature, radiation, and humidity of the surrounding space. This inexpensive robot is operated by an Nvidia Jetson NanoTM. All controlling and image acquisition programs and routines are written in python for ease of integration with institution-specific operating systems such as EPICS.
