<p dir="ltr">A BPM has unique features that differentiate it from a 2D detector. For starters, it has no 2D image. It has scaling information for each sensor (the gain and offset of the current amplifiers, in the most common design), each of which has a host of settings to be documented. The various fields and assumptions of NXdetector are a poor fit to describe BPMs.</p>

Hi Eugen,<br>
A BPM is essentially a 2D detector and so it should follow
NXdetector. In fact, wouldn't it make sense to just use NXdetector
to represent a BMP?<br>
<br>
Cheers,<br>

Hi folks,<br>
I have currently a request for storing data from a beam position
monitor within a NeXus file.<br>
As we currently have no base class to store such data and beam
position monitors are rather common<br>
I made a small draft for a new base class NXbpm (see the attached
PDF). <br>
It is currently in a very early stage. I guess the best approach
would be that we try this at<br>
DESY and discuss this during the next NIAC meeting in two years. <br>
<br>
Can you guys please have a look on the draft and let me know if
there are some things I have missed <br>
or if you have some good ideas about items to add or do
differently?<br>
<br>
best regards<br>
Eugen<br>
