High-resolution electro-magnetic calorimetry with noble liquids

Abstract: 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 transverse electrode structure) and of ATLAS (sampling calorimeter with longitudinal electrode structure), are summariz… Show more

“…It is also the best choice, apart from the price, for low energy, low background experiments, where radiopurity is of prime importance. In fact, xenon is free of long living isotopes whereas natural argon has 39 Ar and 42 Ar ␤-emitting radioisotopes with half lives of 269 and 33 years, respectively. Although the concentration of these isotopes in natural argon is of the order of 10 y21 grg w x 36,37 , it can become a disturbing source of background for experiments searching for very rare events, especially if these events involve a small deposition of energy in the detector medium, as it is the case of the direct detection of dark matter.…”
