Dear user,
If the beam is monocromatic, the second peak may be due to cuK-alpha 2 radiation ro if not so, it may be due to k-beta radiation.For K-beta line, you may use a ni filter to absorb it. For k-alpha , you may change the divergient slit of the primary side ( 0.2mm or 0.4mm slit ) or the detector slit ( 0.1mm to 2mm) to cut the unwanted peak.It is also helpful to do the fine adjustment for the monocromator repeatedly to get the ultimate result.
Thanks

Dear all,
We are recently installing a XRD, and there is a huge peak occurred in the
3-7deg (2T) which is masking the useful signals from the sample. How can we
eliminate the big peak there?
We use 40kW, 30mA CuKa x-ray, divergent and receving slits are used,
many thanks,
stephen Chui
