The beamline

The TomoWISE beamline as five areas you can jump to: the three stations the beam passes through, plus the controls that drive them and the resources they draw on. Design-phase.

The beamline divides into two kinds of thing. Along the beam, in order, sit the three stations: the Source that delivers and conditions the beam, the Sample stage that places the specimen in it, and the Detector that records what comes through. Cutting across all three are the two shared concerns: the Controls that drive the hardware, and the resources the beamline draws on. Two access-gated hutches contain it: an optics hutch (sources, front end, optics) and an experiment hutch (both endstations and the detector).

The stations are containment trees of apparatus (Asset.parent_id); controls relate to that apparatus sideways, by controller_id, and a resource is a Supply in its own right. So the list reads as one row of peers, but the first three share an axis the last two cross.

Stations

  • Source: the shared beam delivery. Two switchable insertion devices (CPMU14 undulator, 3T3PW wiggler) feed a front end of masks and a heat absorber, then an optics hutch of filters and a multilayer monochromator (MLM), then the safety shutters. The operation mode selects source, filters, and whether the MLM and KB optics are in the beam.
  • Sample: the sample stage, two stations sharing the detector. The microtomography station (~45 m) carries the rotary stage, sample positioning, laminography tilt, sample-side slits and fast shutter, and a slip ring; the nanotomography station (~49 m) adds the KB mirror pair and a six-axis sample manipulator on a granite support.
  • Detector: one gantry on 7 m floor rails serves both stations (45 m to the 52 m hutch wall), carrying interchangeable microscopes (MicLFOV, MicHR) composed as the Microscope Assembly, and four shared cameras.

Shared

  • Controls: the MAX IV Tango/Sardana control stack and the rotary-stage-master trigger scheme.
  • Resources: the continuously-available supplies a run needs (photon beam, cooling water, vacuum); carried in the descriptor, with no operations page yet in this design phase.

  • Inventory: the full planned CORA Asset model (every device by parent_id, with Families, target Models, and pending confirmations). The hutch PSS permit signals are MAX IV facility signals, not yet named (see Open questions).
