Beam Center Corrected
This is a follow up to the post Is the Beam Center Correct? which shows how to determine if your beam center is correct. Today, we will be looking at how correct the beam center if it is wrong.
The computer screen is not as clear as I would like, but think you will be able to follow along (watching the video full screen should help). The audio is a little hard to hear at the end since I am speaking directly behind the camera. Anyway, I would love to hear your thoughts.
Here is the post on the format of a comm file. We also had a post on the overview of using ipmosflm, which should help you follow along with this post if you get stuck. When I bring up ‘previous set’ am referring to the offset seen in the Is the Beam Center Correct? video.
I would love to hear some feedback on this! Can you follow along? Do you like having videos? I would also love hear suggestions on screen recording software (linux or windows).

Hey Sean, why don u try one of those softwares which captures ur screen as video.. For example Camstudio.. its good.. you can even zoom into a limited areas of the screen..

i like the video idea, but for this example it was way too small to see. the audio was fine.
as for beam centering, what if you don’t have ice rings?

Hi chempilot,
Thanks for the feedback. If you don’t have ice rings you can select ‘Beam (select point)’ which will allow you place the beam center directly. I like to use the backstop or detector layout/pattern as a reference.
