Edgeless Si sensor modules for SIRIUS Synchrotron Light Source

ADVACAM Oy is proud to supply Medipix3 1x6 edgeless modules to Pi-Tecnologia (PITEC) for their PIMEGA detectors. This groundbreaking technology is being used at the Brazilian Synchrotron Light Laboratory (LNLS), in Campinas, São Paulo State, in Brazil.

As stated by the LNLS website, the new brazilian synchrotron lightsource will be the largest and most complex scientific infrastructure ever built in Brazil and one of the first fourth-generation synchrotron lightsources of the world.

The Synchrotron Light Source is a large machine, capable of controlling the movement of charged particles, typically electrons, to produce Synchrotron Light.

What is a Beamline?

According to LNLS, the synchrotron light is guided to experimental stations, called Beamlines (image above), installed around the Storage Ring. It is in the beamlines that the radiation passes through the samples to be analysed.

Synchrotron Light Sources can accommodate several beamlines, and experiments are carried out using different techniques, such as Spectroscopy (from Infrared to X-rays), X-ray scattering, crystallography, tomography and others.

The Cateretê (Coherent And TimE REsolved scatTEring) group is responsible of the CATERETÊ beamline. The synchrotron light source will be optimised to perform Coherent X-ray Diffraction Imaging (CXDI) and X-ray Photon Correlation Spectroscopy (XPCS). Among its applications are the investigation of the dynamics of biological phenomena and nanoscale structures in the areas of petroleum, catalysts and polymers, as well as in solving problems of the food, pharmaceutical and cosmetic industries.

The CATERETÊ beamline will provide unique capabilities in biological and soft materials imaging and dynamics experiments with particular focus on the application of coherent X-ray scattering and diffraction techniques. Coherent X-ray diffractive imaging (CXDI) and X-ray photon correlation spectroscopy (XPCS) experiments will be at the heart of the activities planned at the Cateretê beamline, but also time-resolved small angle X-ray scattering, which will benefit of the high flux of the source. The Cateretê beamline will operate from the tender X-rays, 3 keV up to 12 keV, for imaging of biological and nanomaterials, making the most of the coherence properties of the radiation provided by Sirius.

Edgeless silicon sensor modules and PIMEGA detectors

Pi-Tecnologia (PITEC) has partnered with LNLS to execute this project.

ADVACAM produces Medipix3 1x6 edgeless modules for these innovative projects. Each module is composed of 6 pcs of MPX3-RX V2 readout ASICs and a large 14 mm x 85.5 mm monolithic edgeless sensor. The thicknesses of the manufactured edgeless sensors were 300 µm and 675 µm.

PIMEGA-135D detector composes of 6 pcs of edgeless sensor modules tiled closely to each other to avoid inactive image area. The detector has 2,359 kpx (1536 x 1536) and cover a detection area of 85 mm x 85.5 mm. The high frame rate operation is essential in the synchrotron application and the PIMEGA-135D is able to operate at 2,000 frames per second.
