Lambda comes in different flavours.

Developed at CERN’s laboratories, LAMBDA is based on the Medipix3 readout chip.

It is designed for synchrotron experiments requiring high spatial resolution, high sensitivity and extremely high speed.

LAMBDA is ideally suited for these applications:

  • XPCS
  • Time-resolved measurements
  • Ptychography
  • SAXS
  • Diamond anvil cells and imaging.

Single-photon-counting circuitry means that LAMBDA provides effectively noise-free operation. This is critical for achieving high image quality during fast measurements and for discriminating against fluorescence.

LAMBDA’s small pixel size  (55 µm) means that it offers the best high-resolution imaging available, with flexible in-pixel circuitry.

LAMBDA modes

LAMBDA supports a variety of modes:

  • High-speed readout mode up to 2,000 fps & no dead time between images
  • 24-bit counter depth mode 1 ms readout time between images
  • Energy binning mode photon hits are divided into two user-defined energy bins.

This can be used, for example, to discriminate between the first beam harmonic and higher harmonics.

The LAMBDA readout electronics were developed at DESY. They can read out a large 750K module at 2,000 fps using high-speed optical links.
