Differential scanning calorimetry (DSC) and isothermal calorimetry have been applied extensively to the analysis of light metals, especially Al based alloys. Isothermal calorimetry and differential scanning calorimetry are used for analysis of solid state reactions, such as precipitation, homogenisation, devitrivication and recrystallisation; and solid–liquid reactions, such as incipient meltin...
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 ...
In the past 50 years, calorimeters have become the most important detectors in many particle physics experiments, especially experiments in colliding-beam accelerators at the energy frontier. In this paper, we describe and discuss a number of common misconceptions about these detectors, as well as the consequences of these misconceptions. We hope that it may serve as a useful source of informat...
We report late-time observations of the radio afterglow of GRB 030329. The light curves show a clear achromatic flattening at 50 days after the explosion. We interpret this flattening as resulting from the blast wave becoming transrelativistic. Modeling of this transition enables us to make estimates of the energy content of the burst, regardless of the initial jet structure or the distribution...
In this Tutorial, we present an overview of the development photopyroelectric (PPE) technique from its beginning in 1984 to day. The Tutorial is organized into five sections, which explore both theoretical and experimental aspects PPE detection as well some important spectroscopic calorimetric applications. “Introduction” section, fundamental basics photothermal phenomena state-of-the-art techn...
We provide the theoretical basis of calorimetry for a class active particles subject to thermal noise. Simulating AC-calorimetry, we numerically evaluate heat capacity run-and-tumble in double-well and periodic potentials, systems with flashing potential. Low-temperature Schottky-like peaks show role activity indicate shape transitions, while regimes negative appear at higher propulsion speeds....
