DESCRIPTION:Speakers: Cecilia Casadei (MAX IV Laboratory)\nThe rise of 4th
  generation sources\, including the MAX IV Laboratory 3 GeV ring\, has ena
 bled new possibilities to study dynamics using crystallography. The MicroM
 AX beamline is a new beamline focussed on providing optimal X-ray characte
 ristics for serial (SSX) and time-resolved (TR-SSX) crystallography at MAX
  IV [1]. The beamline emphasizes a flexible sample environment for standar
 d and bespoke experimental setups while also supporting high-throughput si
 ngle crystal data collections at the BioMAX beamline which has operated si
 nce 2017 [2]. \nThe MicroMAX user program opened in May 2024 and has perfo
 rmed experiments with SPINE-based fixed targets\, high-viscosity extrusion
  and microfluidics and single-crystal oscillation data collections. Sample
  handling and positioning is supported by the MD3-up micro diffractometer\
 , Oxford cryojet\, and ISARA automated sample mounting platform (including
  crystallization plates). Time resolved techniques are enabled by a nanose
 cond pump laser (210-2600 nm)\, Celerotron X-ray chopper (0\,8-70% duty cy
 cle) and one of either an Eiger2 X 9M CdTe photon counting hybrid pixel de
 tector or Jungfrau 9M Si integrating hybrid pixel detector (on-loan from P
 SI). \nOptical elements allow for a beamline flux from 10^13 photons/s (0.
 1% bandwidth double crystal monochromator) to more than 10^14 photons/s (1
 % bandwidth multilayer monochromator) with an optimal 1x1 μm beam focus u
 sing beryllium lenses/K-B mirrors. Beamline controls are from within MXCuB
 E\, with additional live feedback and CrystFEL autoprocessing pipelines to
  provide immediate feedback and rapid map generation. Sample pre-character
 ization is supported by an offline laser and spectroscopy lab in the secon
 dary experimental hutch and dedicated sample environment and preparation l
 abs.\nHere we present the current status of MicroMAX beamline and recent d
 evelopments in sample preparation and data handling under a variety of exp
 erimental contexts. This work emphasizes the technical developments for a 
 highly flexible TR-SSX end station in context of SSX/TR-SSX experiments al
 ready being conducted by the MicroMAX user community.\n\nMicroMAX is funde
 d by the Novo Nordisk Foundation under the grant number NNF17CC0030666.\n\
