C-Therm Announces Two Additional Webinars to Fall Schedule

Title: Thermal Conductivity of Diamond-Loaded Glues for the ATLAS Particle Physics Detector

Date: Wednesday, September 15th, 2010
Time: 1PM Eastern / 10AM Pacific
Speakers: Eric Ouellette (University of Victoria)

Description: The ATLAS experiment is one of four large general-purpose particle detectors at the Large Hadron Collider (LHC) at the CERN laboratory in Geneva, Switzerland. ATLAS has been collecting data from the collisions of protons since December 2009, in order to investigate the conditions that existed during the early Universe and the origins of mass, as well as other topics in fundamental particle physics. The innermost layers of the ATLAS detector will be exposed to the most radiation over the first few years of operation at the LHC, in particular the layer closest to the beam pipe, the B-layer. To compensate for its degradation, it will be replaced with an Insertable B-Layer (IBL) around 2016. The design of and R&D for the IBL is ongoing, as the hope is to use the most current technologies in the building of this new sub-detector layer. One topic of interest is the use of more thermally conductive glues in the construction of the IBL, in order to facilitate in the dissipation of heat from the detector. In this paper the measurement and use of highly thermally conductive glues, in particular those that are diamond-loaded, will be discussed. The modified transient plane source technique for thermal conductivity is applied in characterizing the glues across a wide temperature range.

Title: Thermal Conductivity of Magnesium Hydrides

Date: Thursday, October 14th, 2010
Time: 1PM Eastern / 10AM Pacific

Description: Magnesium has a high hydrogen storage capacity but its temperature of operation is too high and the hydrogen sorption kinetics too slow for practical applications. These two aspects have been intensively investigated and many synthesis or processing methods have been proposed. One well known processing method of metal hydrides is high energy ball milling. Through ball milling, particle size reduction, nanocrystalline structure, and formation of metastable phase are obtained. However, the impact of these changes on thermal conductivity is not well known. For practical applications, good thermal conductivity is a key property to achieve acceptable hydrogen sorption kinetics. It is essential to have precise measurement of this parameter as a function of material structure and processing method. In this webinar we will report measurements of thermal conductivity via the modified transient plane source (MTPS) technique of magnesium-based hydrides before and after ball milling and other processing methods.
