The SDHCAL
is a stainless steel hadronic sampling calorimeter made with glass resistive plate chambers (GRPC
) with embedded readout electronics as sensitive medium it is the first technological prototype of a particle flow algorithm (PFA
) oriented calorimeter developped within the CALICE
collaboration.
The SDHCAL
has been designed for the ILD
detector of the International Linear Collider project (ILC
). For ILD
, an ingenious mechanical structure avoiding cracks has been designed. This design implies variable length for the sensitive medium with a maximum size of 0.9x3m^2. The challenges for this design are to obtain GRPC response homogeneity for large area, an active detector with a thickness of only a few mm including the embedded low power consumption electronics and all the services on one side of the detector.
A technological prototype meeting all the above challenges has been conceived as a demonstrator. It is made with a stainless steel selfMsupporting structure able to hold up to 50 GRPC
cassettes. A cassette is 11mm thick and is a steel cover containing the GRPC and the embedded electronics.
