Hi Michele!
-did you go in steps from 10 to 40 C? did you monitor drifts while doing
that? has the energy range, where you do not observe problems, changed?
In fact I was not planning to do that cause 40ºC
seems to be the monos basal temperature. In addition, I operated n
r idea. In the case
I don't used it right now, I'm sure it'll be useful in my life someday!
:)
Thanks one more time for the valuable help,
Lucas.

Hi,
I commissioned and made
As I recall, your setup down there is similar to mine (ALS 8.3.1), so
perhaps I can be of some assistance.
There are only two things that can cause changes in energy: d and
theta. This is because lambda=2*d*sin(theta). If the change is
entirely due to thermal expansion of the mono crystal,
Dear Mark, thanks for your answer!
Yes, there is an actual change in energy and I guess my problem does not
have a single source!
In the case you know someone who faced/have faced a similar problem
around please tell me.
Brazilian regards,
LS.

Hey Andrew! Thanks for answering!
Does someone have experience in minimize energy instabilities in
beamlines?
Are you sure it's an energy instability and not an intensity one?
It's quite rare to see energy instabilities from a well calibrated
monochromator. All monochromators should be in a clos
Hello all!
Does someone have experience in minimize energy instabilities in

MX2, our new beamline devoted to MX experiments, are facing problems
with energy drifts. As far as we could notice, theses drifts are results
of the contribution from several sources - possibly electron beam
