LAMBDA is a next-generation pixel detector for X-rays, based on Medipix3 technology. It is a photon-counting detector, making it effectively noise free, and it offers a high frame rate of up to 24,000 frames per second (with no readout deadtime) and a small pixel size of 55 µm. It is available in a wide variety of sizes and configurations for different applications, and can be equipped with different sensor materials to allow high detection efficiency even at high X-ray energies. The system also has “colour imaging” capabilities, where X-rays hitting the detector can be divided into two energy ranges. Developed by DESY for use at the PETRA-III synchrotron, the system is designed for high reliability, and has external triggering and gating capability for synchronisation with the rest of the experiment. It can be easily integrated into common beamline control systems.
DETECTOR SIZES
We offer a range of detector sizes, ranging from 256 by 256 pixels to up to 10 megapixels area. The systems are designed to be compact and lightweight – for example, the LAMBDA 750k weighs approximately 2 kg. As well as our standard systems listed below, larger systems (above 1 megapixel) can be custom-built with different geometries – for example, a long narrow detector, or a non-rectangular layout. In our LAMBDA-Flex design, one or more compact sensors of 256 by 256 pixels are connected to the readout electronics by flexible cables. These sensors can be freely positioned, making them ideal for experiments with limited detector space, such as RIXS.
To reduce air scattering in experiments at lower X-ray energies, we also offer systems that can be operated in vacuum. The in-vacuum options are described in more detail on the AMBER product page.
