NLaK Sample in holder in monochromator.
NLaK sample in X-Ray setup. We decided to do first set of measurements using only NLaK sample placing it in the centre of the X-Ray setup shelf, directly under the source. That allows to be sure about the dose rate.
Calibration of X-Ray setup was done using dosimeter with 15mm radius circular sensor, since dose depends on the area we normalized dose for NLaK piece (28x8 mm). Dose for 7.5 s using dosimeter on shelve 8 was measured to be 81.4 R, so for NLaK it should be ~25R.
We used monochromator to quantify influence of irradiation by measuring transmission. We also had Fused Silica plate used as reference to normalize NLaK measurements. Below one can see that the beam of monochromator nicely fits in samples.

We don't see much of a scattering of the beam:
