Abstract
The very forward region of a detector at the International Linear Collider (ILC) is particularly challenging area for instrumentation. Forward calorimeters should provide luminosity measurement with the high precision, tuning of the beam parameters, detector hermeticity at lowest polar angles and shielding of the central detectors from backscattered particles. High-energy electron identification is particularly important to veto Standard Model background to new particle searches. In addition, extreme radiation hardness in required for the innermost calorimeter due to several tens of TeV depositions of beamstrahlung remnants per bunch crossing.
