Electro-Calorimetry

High-resolution electro-magnetic calorimetry with noble liquids

Electromagnetic calorimeters with noble liquids and their limits in resolution are discussed. The origins of “initial” current measurement in calorimetry are retraced and the performance and first results of the NA48 calorimeter (quasi-homogeneous calorimeter with longitudinal electrode structure) are presented. Results of the prototype calorimeters of KEDR (quasi-homogeneous calorimeter with t...

Gravitational Calorimetry

I generalize the quasilocal formulation of thermodynamics of Brown and York to include dilaton theories of gravity as well as Abelian and Yang-Mills gauge matter fields with possible dilaton couplings. The resulting formulation is applicable to a large class of theories including two-dimensional toy models and the low energy limit of string theory as well as to many types of matter such as mass...

Micromegas for imaging calorimetry

Gaseous detectors have been used in sampling calorimeters for several years and still remain an attractive option for future collider experiments. The use of Micromegas chambers as active elements of a hadronic calorimeter was proposed a few years ago and stirred up exciting developments of this technology. Basic building blocks of large size chambers acting as signal generating and processing ...
