European Synchrotron Radiation Facility: My name Work at esrf in France, grenoble, which is a research institute which provides 40 x ray bl. Esrf is surrounded by a lot of ri A storage ring provides 40 bl which make imaging by using ccd cameras Tje brilliance of the beam is so high that pixels of the ccd can be saturated by an exposure time of a couple of ms Morever the readout speed of the camera on the marketcompare to this short exposure time gives a poor duty cycle. In the aim to improve this, esrf has developed a fast ccd camera. 4-May-19 The ESRF FReLoN Detector ISG

A Fast Readout Low Noise Camera High Readout Speed Scientific Grade Image Well potential 10 V Photoelectric effect: 1.1 eV/e- Memory zone Multi channels: ATMEL 7899M 1. Crosstalk rate: < 1/216 1 / 60000 grey levels 2. Homogeneous Responses - Real Dynamic Range: 1 / 16000 - Linearity Error: < + / - 0.3 % FS 1 2 4 3 Wich combines both: high speed readout and scientific grade image We chose the muti-channel atmel chip It s 1 image zone of 2k 2k pixels ans 4 readout outputs There are 2 main challenges: To have no crosstalk Example: To get homogeneity response for all the 4 channels Finaly, altrough a high multichannel readout speed we got a real 14bit dynamic range and a linearity error less than 0.3 % fs
