ST0.1 Samples fork

K- and L- edge materialsfor both low and high

energy photons,attenuator test materials

for high energywavefront preservation

Fifteen 5x5 mm sample slots available at any time,

rapid turn around

Revision Three in progress, a combination calorimeter

and acoustic-impulsemonitor for measuringphoton pulse energy.

YAGXRAY pop-in currentlyresides here, the YAG screen

will be added to the bottom ofthis monitor.

ST0.3 Rotary B4C Target

Allows inspection of B4CMPS shutter without interruption

of photon experiments.

Better optical setup, nomirror required.
