(Utrecht U. ; Nikhef, Amsterdam ; Utrecht U.) ; Chujo, Tatsuya (Tsukuba U. (main)) et al.
A silicon-tungsten (Si-W) sampling calorimeter, consisting of 19 alternate layers of silicon pad detectors (individual pad area of 1~cm$^2$) and tungsten absorbers (each of one radiation length), has been constructed for measurement of electromagnetic showers over a large energy range. The signal from each of the silicon pads is readout using an ASIC with a dynamic range from $-300$~fC to $+500$~fC. [...]

Development and characterization of a large area silicon pad array for an electromagnetic calorimeter
/ Mukhopadhyay, Sourav (Bhabha Atomic Res. Ctr. ; HBNI, Mumbai) ; Chandratre, Vinay B. (Bhabha Atomic Res. Ctr. ; HBNI, Mumbai) ; Muhuri, Sanjib (Calcutta, VECC ; HBNI, Mumbai) ; Singaraju, Rama N. (Calcutta, VECC) ; Saini, Jogender (Calcutta, VECC) ; Nayak, Tapan K. (Calcutta, VECC ; Bhubaneswar, NISER ; CERN)
We present the research and development work of the first version of a 6*6 array of silicon pad detectors, carried out in India, for the proposed forward calorimeter (FOCAL) as part of the ALICE collaboration upgrade program at CERN. The primary motivation is to develop a large area silicon pad array realizing the challenging requirements of high-energy physics experiments such as low leakage current, high breakdown voltage and evaluate its performance as an active layer in the prototype silicon tungsten (Si-W) electromagnetic (EM) calorimeter.

Large area Gas Electron Multiplier (GEM) detectors have been the preferred choice for tracking devices in major nuclear and particle physics experiments. Uniformity over surface of the detector in terms of gain, energy resolution and efficiency is crucial for the optimum performance of these detectors. [...]

Isothermal compressibility of hadronic matter formed in relativistic nuclear collisions
/ Mukherjee, Maitreyee (Bose Inst., Kolkata) ; Basu, Sumit (Wayne State U.) ; Chatterjee, Arghya (Calcutta, VECC) ; Chatterjee, Sandeep (AGH-UST, Cracow) ; Adhya, Souvik Priyam (Calcutta, VECC) ; Thakur, Sanchari (Calcutta, VECC) ; Nayak, Tapan K. (Calcutta, VECC ; CERN)
We present the first estimates of isothermal compressibility (\kT) of hadronic matter formed in relativistic nuclear collisions ($\sqrt{s_{\rm NN}} = 7.7$ GeV to 2.76~TeV) using experimentally observed quantities. \kT~is related to the fluctuation in particle multiplicity, temperature, and volume of the system formed in the collisions.

New generation high-energy physics experiments demand high precision tracking and accurate measurements of a large number of particles produced in the collisions of lementary particles and heavy-ions. Silicon-tungsten (Si-W) calorimeters provide the most viable technological option to meet the requirements of particle detection in high multiplicity environments. [...]
