The Pilatus 6M-F detector, which is installed on ID23-1 and ID29 beamlines, has an active area of 424 x 435 mm2 (2463 x 2527 pixels, which are 172 microns in size).

The readout time per frame is 3ms and the maximum speed is 25Hz. In this way 25 images per second are collected while operating in shutterless mode, allowing to collect a complete dataset in a few minutes.

Data quality is usually higher than the one collected on a CCD thanks to absence of readout noise, zero background counts, zero point spread and no shutter synchronization. Furthermore the 20bit dynamic range permits to collect high and low resolution pass at once.

How to collect the best data

In order to obtain higher data quality collect data in fine slicing (i.e. Oscillation range smaller than half of the estimated mosaicity). Usually an oscillation range of 0.1 degree is a good choice, in combination with low Transmission. It is recommended to use the Characterization in MXCuBE2 to obtain the best data collection plan, with adequate transmission, resolution and oscillation range.

Image visualisation

ALBULA VIEWER is a fast and easy-to-use program supplied by DECTRIS, that displays PILATUS and allows optimal visualization of your data. 

Diffraction images can be viewed with adxv (version 1.9.7 or superior) or MOSFLM (version 7.0.7 or superior) and iMOSFLM
