We have produced and tested scintillator strips by injection molding method. The newly fabricated scintillator strip stability for ILC scintillator ECAL is studied. Here we report a stability test using beta ray source for more than 3 months. The measured MIP peak position has tendency of gradual change of -0.013%/day.
We have studied the dimple shape for scintillator strips of ILC ECAL....
A highly granular silicon-tungsten electromagnetic calorimeter (SiW-ECAL) is the reference design of the ECAL for International Large Detector (ILD) concept, one of the two detector concepts for the detector(s) at the future International Linear Collider. Prototypes for this type of detector are developed within the CALICE Collaboration. The technological prototype addresses technical...
The Silicon-Tungsten ECAL (SiW-ECAL) of ILD will require about 10,000 detector slabs of 1.4 to 1,8 m in length. For the ease of building and testing, the slabs are made of stitched detector elements of 18×18 cm², composed of a Front-End Board (FEB), hosting the readout ASICs for 1024 channels, on which the Silicon sensors are glued.
Various types of detector elements have been successfully...
The traditional purpose of the ECAL of the ILD experiment is to measure neutrals
(especially photons but also the interacting neutral hadrons) while tracking the
charged particles for particle flow algorithms.
A highly granular Silicon-Tungsten ECAL (SiW-ECAL) is particularly suited for these tasks.
The SiW-ECAL faces many technical challenges: the main ones have been solved,
some...
