Project P6

Very Forward Calorimetry

Participants: DESY, UHH, AGH, LNF; IFJ; ESR: 2 × 3 yrs (contact person: W. Lohmann, DESY)

One of the functions of the ILC forward calorimeters is to measure the luminosity delivered by the machine with an accuracy of better than 10^-3 resulting in mechanical precision requirements on the micrometer level. The calorimeters are exposed to e⁺e⁻ pairs from beamstrahlung, a new phenomenon at the ILC. They have to be equipped with radiation hard sensors and fast and low power FE electronics to allow feedback for beam tuning. Both calorimeters must be compact and finely segmented to reach the required performance.

There is already a close collaboration between AGH Cracow, IFJ Cracow and DESY within the ILC-FCAL and EUDET projects. In this framework, the ESRs will work on the following topics: Monte Carlo studies to optimise the shape and granularity of the calorimeter, sensor development for both calorimeters (Silicon, GaAs and CVD diamond), sensor performance studies in the laboratory and test beam, development of ultra-thin sensor planes for both calorimeters, integration of sensor planes and FE ASICS, preparation of a fully equipped prototype module for performance studies in the EUDET test beam.

AGH Cracow will focus the activities on the development of the FE ASICS (see P11) and DESY on the sensor development and sensor plane tests. Monte Carlo simulations and integration of sensor planes and FE ASICs will be done in a common effort.
