"Name of your Project"

Q. What are the goals of this R&D project. How does this R&D project address the needs of one or more of the detector concepts?

A. The goal is to propose an Electromagnetic calorimeter having a sufficient high granularity at a reasonable number of channels and at a reasonable cost. The shower granularity should be defined by a restricted number of Si-pad planes while the energy can be measured by larger size scintillator tiles. This is addressed to the LDC concept were alternative detectors made only by silicon pads as active material imply an huge number of channels and an extremely high cost, and , consequently, to the GLD concept.

Q. If there are multiple institutions participating in this project, please describe the distribution of responsibilities.

A. The unique paying institution was INFN. The ITE Warsaw contribution was the Si pad production committed by INFN

Q. Are there significant recent results?

A. Yes ! As it is described in the notes and proceedings of conferences where the results were presented, the prototype was tested in different beam lines giving good results. In particular: the energy resolution is in the range 11-11.5%/sqrt(E) with a negligible constant term, the energy uniformity is at the level of few percents, the position reconstruction is about 2 mm at 30 GeV and the electron hadron separation is better than permille level.

Q. What are the plans for the near future(about 1 year)? What are the plans on a time scale of 2 to 3 years?

A. The lack of human resources due to additional engagements of the involved people imposes, at least on a short time basis, a delay on the expected progress of this project which could be recovered just by fresh injection of new actors in this game.

Q. Are there critical items that must be addressed before significant results can be obtained from this project?

A. It would be fruitful to exploit to the best level the particle to particle separation obtainable with this detector

Q. Is the support for this project sufficient? Are there significant improvements that could be made with additional support?

A. NO ! the financial support was reasonable in the past but it is missing for the future.
