Applications of LAMBDA Even the best experiment at the best light source is worthless if the employed detection system is not up to the task at hand. This is especially true at current 3rd generation synchrotrons like PETRA III. Several experiments have been successfully conducted utilizing LAMBDA’s unique capabilities.

Rheology

Novel     rheology     experiments     require detectors    that    provide    highest    spatial resolution     at     highest     frame     rates. These    requirements    derive    not    only from     the     transitory     nature     of     the investigated   phenomena,   but   also   from the    uncommon    experimental    layouts which     mandate     compact     detection systems          without          cumbersome supports.   LAMBDA   is   ideally   suited   for this   application   due   to   its   small   form factor     and     limited     supply     lines     in combination with its unique properties.

Lead lettering on fan

LAMBDA 350K GaAs

Below   is   an   X-ray   movie   of   a   computer fan,   taken   at   1000   frames   per   second with    a    GaAs    LAMBDA    detector.    To provide     interesting     contrast,     letters were   taped   to   the   fan   blades.   Thanks to   the   high   sensitivity   and   zero   noise   of the    LAMBDA    GaAs    system,    the    high speed     movie     shows     clear     contrast between   the      fan   blades,   housing   and lettering, despite the short shutter time.

Snowflakes from Indium

LAMBDA 750K Silicon

By   running   a   LAMBDA   silicon   module at   2000   frames   per   second   in   front   of an    X-ray    tube,    we    made    a    movie    of flakes   of   scrap   Indium   foil   in   free   fall.   In real   time,   the   flakes   take   only   60   ms   to cross    the    detector    –    the    movie    is slowed   down   by   a   factor   of   67.   This high-speed   X-ray   imaging   can   be   used to study rapid changes in samples.

High-Z modules

LAMBDA 350K GaAs

X-ray   images   of   a   USB   stick   with   an   X- ray     tube     show     that,     after     flat-field correction,   the   GaAs   LAMBDA   module delivers a high quality image.

Applications

Laboratory Radiography

LAMBDA 750K Silicon

Using   an   X-ray   tube,   we   X-ray   imaged a   sardine   can.   The   LAMBDA   detector shows     high     sensitivity     and     image quality,   with   the   fishbones,   tissue   and scratches   in   the   can   all   being   clearly visible.

Key features:

Effectively zero noise (photon counting) 55 µm pixel size Up to 2000 frames per second Deadtime-free readout 1536 by 512 pixels (85 mm by 28 mm) Energy binning capability

Diamond Anvil Cell

LAMBDA 750K GaAs

At the PETRA-III beamline P02.2 a sample of CeO 2  was placed inside a diamond anvil cell. The X-ray beam had a photon energy of 42 keV; images were taken with 1 ms illumination time.
