Description
The CALICE collaboration is currently developing an engineering
prototype of an analog hadron calorimeter for a future linear
collider detector. It is based on scintillating tiles that are
individually read out by silicon photomultipliers. The prototype
will contain about 2500 detector channels, which corresponds to one
calorimeter layer and aims at demonstrating the feasibility of
building a detector with fully integrated front-end electronics. The
SiPM signals are read out by the SPIROC chip, which is an
auto-triggered, bi-gain, 36-channel ASIC developed to measure the
charge from one to 2000 photoelectrons and the time with a 100 ps
accurate TDC. The concept and engineering status of the calorimeter
prototype, the different subcomponents, the DAQ system, the
functionality of the SPIROC, as well as results from the DESY test
setups are reported here.
