Inventory

The CORA Asset model for the ARPES branch of ESM modelled today: the planned device tree and what still needs confirming.

This cut models the XF:21IDA/B/C optics and the XF:21ID1-ES ARPES endstation; the XPEEM/LEEM branch and the simulated devices are deferred (see Model). It is the cross-cutting reference view of the Source walk and the Sample and Detector pages, authored from the same beamline.yaml descriptor.

ESM introduces one new family (ElectronAnalyzer, since graduated once SST earned the 2nd SES), graduates Manipulator into the catalog (its 2nd UHV manipulator after SIX), and reuses the rest, including the graduated GratingMonochromator (its 3rd PGM). Control handles are filled from the profile collection; no vendor Models are bound.

The Asset tree

Root Asset ESM (tier = Unit, facility_code = nsls2); sub-systems nest below by parent_id.
