1-ID-A is a first optics enclosure (FOE) which houses the front-end separation window, white-beam filter, white-beam slits, high-energy monochromator, white-beam stop, and monochromatic-beam shutter. The equipment in this station is permanent and, generally, does not change from experiment to experiment.

1-ID-B is an experimental station that can take either white beam or monochromatic beam from 1-ID-A. It can be used for experiments, but it is most often used to condition the x-rays prior to transmission to 1-ID-C/E using refractive lenses and/or a high-resolution monochromator.

1-ID-C and 1-ID-E are the primary experimental stations on the 1-ID beamline, with approximate sizes (L x W x H) of 7 x 4 x 3.3 m3 and 10 x 5 x 4 m3, respectively.Only monochromatic beam can be transmitted to these hutches.

Area detectors widely used at 1-ID are given below. The APS detector pool has additional detectors which can be browsed and requested.

Throughout the beamlines, ion-chambers and PIN diodes are situated to provide (semi) continuous monitoring of the direct x-ray beam intensity.In addition, hutches are equipped with a variety of visible-light cameras which can be used to remotely view the experiment.

Available load frames are listed, all of which can be manipulated on stages with respect to the x-ray beam for in-situ studies.In conjunction with users, additional environments (e.g. liquid, inert gas) have been developed which are compatible with one or more of the load frames.For the MTS additional specialized inserts have been constructed to allow for in-grip rotation, and these are listed as well.

There are hundreds of stages used throughout the 1-ID beamline.Default stacks comprising sample manipulation systems in the 1-ID-E hutch are listed below:

Aerotech stack: this sits on an optical table with Y1 (+-25mm) and 2-axis tilt adjustment capability.
