| < < | A compact and highly granular electromagnetic calorimeter at ILC is one of the key requirements for PFA high precision jet reconstruction and realization of ILC physics potential. R&D of silicon-tungsten calorimeter is the goal of this project. We plan to finalize the optimization of the ECAL geometry (dimensions and number of layers), to build and to test a detector (so-called "active sensor unit", or ASU) with 1024 channels per PCB serving 4 silicon sensors with 16x16 pixels, improve the DAQ software and to work on integration of several ASUs into one ILC full-scale detector. In parallel, we plan to test various designs of silicon sensors and their radiation hardness. | |||||||
| > > | A compact and highly granular electromagnetic calorimeter is one of the key requirements for PFA high precision jet reconstruction, and for full realization of ILC's physics potential. The aim of this project is R&D of a silicon-tungsten calorimeter. The main aim is to further develop the "technical prototype", in which different technical approaches to detector construction are tested and compared. Aspects to be investigated include improvements in electrical design, thinner front-end boards, and silicon sensors of varying thickness. Several beam tests of this prototype are foreseen during the year. An important milestone is to develop a "long slab", chaining several unitary elements to make a large detector element, as will be needed in a full detector. Physics analyses which make significant use of the ECAL will be further studied, with an emphasis on the reconstruction and use of tau lepton decays to probe for new physics. An important aspect will be to quantify how different ECAL design choices (which may, for example, involve significantly different costs) impact such analyses. | |||||||
