Very forward detectors for ILC and CLIC detectors — •Olga Novgorodova — DESY, Zeuthen, Germany — BTU Cottbus, Cottbus, Germany

The instrumentation of the Very Forward Regions in experiments at future linear e+e- colliders is a challenge due to high radiation fields and high rates. Two calorimeters are forseen to perform a fast and a precise luminosity measurement and and extend the detector coverage to very low polar angles. For the calorimeter near the beampipe dedicated GaAs:Cr sensors with very good radiation tolerance were developed. For the luminometer, outside the strong radiation field, silicon sensors are forseen. Two prototypes of sensor planes are assembled with specially developed front-end and ADC ASICS with different feedback schemes of the front-end ASIC. The performance of the full system was studied with a 4 GeV electron beam at DESY. A report of the testbeam results on relevant parameters will be given.
