Support for Rigaku Arc detectors #684

Open dagewa opened 7 months ago

dagewa commented 7 months ago

I have data sets from the two- and three-modular detectors Rigaku HyPix-Arc100 and HyPix-Arc150. Now we support the ROD format (https://github.com/cctbx/dxtbx/issues/11), these data sets can be displayed in dials.image_viewer, but the array is treated as a single panel:

I don't have exact values for the expected angles between panels, except that it should be ~30°

Does it have three flat panels, or three curved panels (like some imaging plates used in neutron crystallography)?

dagewa commented 7 months ago

I was told it is 3 flat panels (with a curved faceplate). I hope this is correct!

BTW, do you have any documentation about the ROD header format? I seem to have lost mine.

I have only those in https://github.com/cctbx/dxtbx/issues/11.

Dug out an old email about the HyPixArc150 that states:

The center module is in the standard "flat" orientation and the 2 neighboring modules are rotated by 38 degrees

dagewa commented 5 months ago

For the HyPixArc100 there are two modules each 19° rotated from the flat configuration, thus 38° between the modules, and it appears to be constructed like 2/3 of the Arc150 detector.
