Proposal for SPS beam time for the CALICE calorimeter prototypes

This note contains the requests of the CALICE collaboration for beam test time at the CERN SPS for the year 2011. Beyond the actual request it gives background information on the CALICE programme and the calorimetric devices to be tested. CALICE asks for in total 20 weeks of time on beam mainly dedicated to test two prototypes of 1 m^3 each. The programme comprises, however, also important technical tests with smaller devices. All expected results constitute vital input to the documents expected from the linear collider detector community in the course of the years 2011 and 2012.
