Pilatus 1M is a 2D detector from Dectris. Its active area is 16.9 cm x 17.9 cm with pixel size of 172 microns, 981 by 1043 array. The big advantages of this detector are the single photon counting capability, point-spread function of 1 pixel and dynamic range of 20 bits (1:1,048,576). There is its technical sheet and user manual.

Pilatus 1M is on use for BioSAXS experiments at the ESRF from March 2010 to now. It was installed, commissioned and used at ID14-3 beamline and from June 2012 on new updated BM29.


In order to be able to use the Pilatus detector for data collection via BxsCuBE GUI: 1) its chiller should be on, 2) p1m-bm29-1 computer on, 3) detector controller on and 4) its server should be running on p1m-bm29-1 computer as opd29.

How to start it: click on the "penguin" icon named "Start Pilatus camserver" on the left display of agatha (by far the most easest way). Or in any X-term window of nela type: "ssh -X opd29@p1m-bm29-1" complete pwd, change directory: "cd p2_det" and start camera server: "./runtvx .

If one wants to use VNC viewer on p1m-bm29-1 computer, you need to tape:

  • on p1m-bm29-1> x11vnc -display :0.0 -rfbport 5900 -shared -forever -bg
  • on nela> vncviewer p1m-bm29-1:0.0

Note the intermodule gaps (7 pixels ~ 1.204 mm in X and 17 pixels ~ 2.924 mm in Y direction) and beamstop shadow, which are masked out when producing 1D curves by radial integration.
