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 2022. Beyond the actual requests, it gives back- ground information on the CALICE programme and the calorimetric devices to be tested. CALICE asks in total for 6 weeks of time on beam, mainly dedic- ated to the test of three systems of electromagnetic and hadronic calorimeters taking combined data. The aim of these tests is both of technological and physical nature: to develop and consolidate the common operation of large prototypes of high granular calorimeters and to study the development of had- ronic showers in different materials leading to improved simulations. In the near future, low power continuous readout and the further addition of tim- ing information will extend the area of possible application of highly granular calorimeters to all the main experiments considered for the future of particle physics.
