Summary
The CALICE Collaboration
The CALICE collaboration is performing R&D for the construction of
highly granular central calorimeters for a future dectector to be
operated at the International Linear Collider (ILC). In the past
five
years the collaboration has successfully desgined, constructed and
operated in test beams a protoype Si-W calorimeter involving
approximately 10000 pads. The test beam results have delivered
valuable information allowing the improvement of the layout of the
active part for the next generation of prototypes, namely a full
scale
calorimeter module being studied as part of the EUDET program. A
detector unit up to 1500mm long is currently under construction.
Aspects like mechanical rigidity and thermal heat dissipation will be
investigated. A particular novel feature of this prototype is the
integration of the very front end electronics into the layer
structure
of the calorimeter. The electronics will be power pulsed with
on-times
suited to the expected bunch structrue of the ILC, in order to meet
the requirements of a minimal heat dissipation of the ASICS) of the
order of 1 MicroWatt per circuit.
