Sector 7 Overview
XOR7 has constructed two beamlines at Sector 7 of the APS:
- 7-ID: an insertion device beamline based on an APS Type-A Undulator
- 7-BM: a bend magnet beam line for fuel spray research (in construction)
Overview of 7-ID
7-ID comprises four large experimental enclosures designated A, B, C, and D.
In 2004, a laser enclosure was also added (7ID-E).
Enclosure 7-ID-A is the first optics enclosure and houses a polished Be window,
an empty x-ray filter unit, a pair of white beam slits, a water-cooled double
crystal diamond monochromator (Kohzu HLD4), and a P4 mode shutter. The beamline
vertical offset is 35 mm.
Enclosure 7-ID-B is a white-, or monochromatic-beam experimental enclosure.
It is equipped with two precision motorized table for alignment and positioning
of experimental equipment. This station is used for white-beam imaging
experiments.
Just downstream of 7-ID-B is a mini-enclosure housing the P5 unit. This acts as
a white beam stop and offset mono-beam shutter to pass monochromatic beam into
downstream enclosures C and D. Continuing downstream, a mono-beam transport takes
monochromatic beam into enclosures C and D. Enclosure C houses a large Huber
6-circle Diffractometer and two optical tables to set up users' experiments.
A streak camera is also available for ultrafast time-resolved detection
(ps resolution). A fs-laser housed in 7ID-E is delivered in 7ID-C to the
diffractometer and streak camera for time-resolved experiments. Synchronization
is achieved in pump-probe geometry utilitizing the RF bunch clock signal brought
from the APS control room on an optical fiber. A commercial diode-pumped
Ti-Sapphire femtosecond pulsed laser is used in both 7ID-C and 7ID-D.
Contiguous to C, enclosure D is instrumented with a 4-circle diffractometer and
a microprobe station for Atomic Physics experiments. A small optical table is
also available for users' experiments.
Status of 7-ID
All three enclosures 7-ID-B, C, and D are operational and accepting General Users
since 2002.
Overview of 7-BM
7-BM comprises two contiguous enclosures, 7-BM-A and B. 7-BM-A is the first
optics enclosure designed to house a white beam slit, double-crystal multilayer
monochromator, a P6 shutter, and a flat mirror. Enclosure B is an experimental
station intended for time-resolved imaging of fuel sprays. 7-BM-B will house two
precision motorized tables for alignment and positioning of experimental equipment,
and advanced choppers and area detectors.
Status of 7-BM
The 7BM beamline has been dedicated to fuel spray research. It is currently under
construction.
