Sector 34ID has two undulator sources and five x-ray enclosures (also called hutches or stations): the first optical enclosure (FOE) 34ID-A, the second optical enclosure (SOE) 34ID-B, the coherent diffraction imaging experiment station 34ID-C, the third optical enclosure (TOE) 34ID-D, and the micro-diffraction station 34ID-E.

Undulator Sources

34ID has two undulators, positioned in tandem along a 5-meter straight section along the ring. Their horizontal directions are separated by 1 μrad. The upstream undulator produces the outboard beam, which eventually goes to 34ID-C for coherent diffraction imaging experiments. The downstream undulator produces the inboard beam that serves micro-diffraction at the E-hutch.

34ID-A

The first optical enclosure has the following components:

• Front-end exit mask, window, and collimator
• Two sets of white-beam slits, one for each x-ray beam
• A few Bremsstrahlung Collimators
• A white-beam deflection mirror that further deflects the 34ID-C beam by 10 mrad in the outboard direction. The deflection would provide enough separation between the two x-ray beams at the C-station so experiments can be performed there without too much spatial constraints
• A white-beam mask/stop for the outboard deflected/transmitted beam
