DESCRIPTION:Speakers: Jie Nan (MAX IV Laboratory)\nThe rise of 4th generat
 ion sources\, including the MAX IV Laboratory 3 GeV ring\, has enabled new
  possibilities to study dynamics using crystallography. The MicroMAX beaml
 ine is a new beamline focussed on providing optimal X-ray characteristics 
 for serial (SSX) and time-resolved (TR-SSX) crystallography at MAX IV [1].
  The beamline emphasizes a flexible sample environment for standard and be
 spoke experimental setups while also supporting high-throughput single cry
 stal data collections at the BioMAX beamline which has operated since 2017
  [2]. \nThe MicroMAX user program opened in May 2024 and has performed exp
 eriments with SPINE-based fixed targets\, high-viscosity extrusion and mic
 rofluidics and single-crystal oscillation data collections. Sample handlin
 g and positioning is supported by the MD3-up micro diffractometer\, Oxford
  cryojet\, and ISARA automated sample mounting platform (including crystal
 lization plates). Time resolved techniques are enabled by a nanosecond pum
 p laser (210-2600 nm)\, Celerotron X-ray chopper (0\,8-70% duty cycle) and
  one of either an Eiger2 X 9M CdTe photon counting hybrid pixel detector o
 r Jungfrau 9M Si integrating hybrid pixel detector (on-loan from PSI). \nO
 ptical elements allow for a beamline flux from 10^13 photons/s (0.1% bandw
 idth double crystal monochromator) to more than 10^14 photons/s (1% bandwi
 dth multilayer monochromator) with an optimal 1x1 μm beam focus using ber
 yllium lenses/K-B mirrors. Beamline controls are from within MXCuBE\, with
  additional live feedback and CrystFEL autoprocessing pipelines to provide
  immediate feedback and rapid map generation. Sample pre-characterization 
 is supported by an offline laser and spectroscopy lab in the secondary exp
 erimental hutch and dedicated sample environment and preparation labs.\nHe
 re we present the current status of MicroMAX beamline and recent developme
 nts in sample preparation and data handling under a variety of experimenta
 l contexts. This work emphasizes the technical developments for a highly f
 lexible TR-SSX end station in context of SSX/TR-SSX experiments already be
 ing conducted by the MicroMAX user community.\n\nMicroMAX is funded by the
  Novo Nordisk Foundation under the grant number NNF17CC0030666.\n\n[1] Gon
