Yes!
It's an X-ray diffractometer!
It's
used by chemists, geologists and biologists to measure X-rays
diffracted from a crystal to calculate the positions of the atoms
it's made of.
Thanks to Michael
H. Dickman for contributing this gizmo! Here he is with
the X-ray diffractometer at Jacobs University, Bremen, Germany |
A
single (very tiny) crystal is mounted on the slender vertical
post at the center of the diffractometer. X-rays are generated
by a tube in the square metal box at the left and are aimed
at the crystal by the hollow metal tube (collimator) to the
left of the crystal. The box on the right detects the diffracted
X-rays. The tube coming down from the top cools the crystal
to -100 C using very cold nitrogen. More information about X-ray
diffraction is online
here. |
