The paper describes a new type of calorimeter that can be quickly put into operation for determining absorbed dose at a point in polystyrene. It also describes a unique method of decreasing drifts in electrical signals caused by temperature gradients. Two calibrated thermistors were placed close together between sandwiched polystyrene discs that were immersed in water. The assembly was irradiat...

Carbon dioxide production, water production, and energy expenditure (EE) determined with 2H2(18)O were validated using a room calorimeter. Nine human subjects (5 males, 4 females) resided in the calorimeter for five to seven consecutive 23.5-h days. Daily carbon dioxide and water production and EE were averaged from calorimeter data and compared with 2H2(18)O results for the same period and for...

The ATLAS liquid argon (LAr) calorimeter system consists of an electromagnetic barrel calorimeter and two end-caps with electromagnetic, hadronic and forward calorimeters. The construction of the full calorimeter system is completed since mid-2004. The detector has been operated with LAr at nominal high voltage and fully equipped with readout electronics. Online software, monitoring tools and o...

Due to an expected increase in radiation damage in LHC, we propose to transform CMS Hadronic EndCap calorimeters to radiation hard quartz plate calorimeters. Quartz is proved to be radiation hard by the radiation damage tests with electron, proton, neutron and gamma beams. However, the light produced in quartz comes from Cerenkov process, which yields drastically fewer photons than scintillatio...

The use of chip-scale calorimeters for research and development has increased during the last two decades. The high sensitivity of these devices allows their use for characterization of very small amounts of sample. However, the potential for using them for screening of highly energetic materials (i.e., explosives) has not been fully explored. In this paper, we present the design aspects of two...

Battery thermal management is critical for high-power battery packs commonly used in electric vehicles (EV) and hybrid electric vehicles (HEV). To design battery thermal management systems properly, obtaining accurate heat generation data from battery modules is essential. To measure heat generation from full-size, multiple-cell battery modules, we developed and tested a custom-made calorimeter...

Commercial coin cells with LiNi0.6Mn0.2Co0.2O2 positive electrode material were investigated using an accelerating rate calorimeter and a Tian-Calvet calorimeter. After cycling charging to the selected states of charge (SOCs), studied under thermal abuse conditions heat-wait-seek (HWS) method heating step 5 K threshold for self-heating detection 0.02 K/min. The onset temperature rise, i.e., run...
