4. within the first few hour, the count sometimes drops to zero again: repeat step 2 and 3; once it stabilizes it seems to only rarely have issues afterward.

3. Put the sample at th=165; you can play with the energy to check for alignment; eg if measuring Ni:
|
|
|
- vortex(865) # center vortex window to Ni-L2,3
|
|
|
- energy(855) # tune energy to Ni-L3 edge => lots of count is on the sample

- mono(845) # go below resonance => counts goes away |
