Very low noise electronics for ILC-calorimeters and ultra fast microwave circuits for dia­mond detectors.

CVD-diamond sensors, polycrystalline as well as single crystal, are promising candidates for the high in-beam intensities projected for FAIR and for TOF (time-of-flight) applications in experiments at FAIR. In the absence of appropriate electronics from other applications, ultra fast microwave analogue pre-amplifier and discriminator circuits have to be developed.

Likewise, the more than 100 000 channels of the front-end electronics for the silicon luminosity detector LumiCal of the for­ward calorimeter (FCAL) for the ILC pose a number of major challenges, like dynamic range, speed, noise, particle occupancy, linearity, signal amplitude, resolution and power consumption. Prototypes of discrete electronic components as well as integrated front-end and ADC conversion ASICs will be designed, produced and tested. A prototype digital readout system will be developed for LumiCal. The devices will be tested extensively on the respective detectors. The digital components will be developed and built in close collaboration with the company Evatronix. The EST and ER will closely work together with the respective detector experts on one side and the analogue circuit designers on the other.
