“…The noise measurement of the high gain state is extracted from dark frames taken under experimental conditions (not shown) and typical values for the Equivalent Noise Charge (ENC) are 320 and 240 electrons in CDS gain low or high, respectively. For the other gain states the noise is higher, but still below the Poisson limit (Mezza et al, 2016a).…”

The European XFEL is an extremely brilliant Free Electron Laser Source with a very demanding pulse structure: trains of 2700 X-Ray pulses are repeated at 10 Hz. The pulses inside the train are spaced by 220 ns and each one contains up to 10 12 photons of 12.4 keV, while being ≤ 100 fs in length. AGIPD, the Adaptive Gain Integrating Pixel Detector, is a hybrid pixel detector developed by DESY, PSI, and the Universities of Bonn and Hamburg to cope with these properties.It is a fast, low noise integrating detector, with single photon sensitivity (for E γ 6 keV) and a large dynamic range, up to 10 4 photons at 12.4 keV. This is achieved with a charge sensitive amplifier with 3 adaptively selected gains per pixel. 352 images can be recorded at up to 6.5 MHz and stored in the in-pixel analogue memory and read out between pulse trains. The core component of this detector is the AGIPD ASIC, which consists of 64 × 64 pixels of 200 µm × 200 µm. Control of the ASIC's image acquisition and analogue readout is via a command based interface. FPGA based electronic boards, controlling ASIC operation, image digitisation and 10 GE data transmission interface AGIPD detectors to DAQ and control systems.An AGIPD 1 Mpixel detector has been installed at the SPB 1 experimental station in August 2017, while a second one is currently commissioned for the MID 2 endstation. A larger (4 Mpixel) AGIPD detector and one to employ Hi-Z sensor material to efficiently register photons up to E γ ≈ 25 keV are currently under construction.

“…The laser intensities were calibrated by measuring the photo-current from a 320 µm thick planar silicon diode and then converting to equivalent number of 12.4 keV photons per pulse. A detailed introduction to the experimental setup and conversion from laser intensity to photons can be found in [18,20]. Figure 5(a) shows the dynamic range for a specific channel using HG0 and G0.…”

A: Gotthard-II is a 1-D microstrip detector specifically developed for the European X-ray Free-Electron Laser. It will not only be used in energy dispersive experiments but also as a beam diagnostic tool with additional logic to generate veto signals for the other 2-D detectors. Gotthard-II makes use of a silicon microstrip sensor with a pitch of either 50 µm or 25 µm and with 1280 or 2560 channels wire-bonded to adaptive gain switching readout chips. Built-in analog-to-digital converters and digital memories will be implemented in the readout chip for a continuous conversion and storage of frames for all bunches in the bunch train. The performance of analogue front-end prototypes of Gotthard has been investigated in this work. The results in terms of noise, conversion gain, dynamic range, obtained by means of infrared laser and X-rays, will be shown. In particular, the effects of the strip-to-strip coupling are studied in detail and it is found that the reduction of the coupling effects is one of the key factors for the development of the analogue front-end of Gotthard-II.
