Seminars
Multidisciplinary seminars are an important mechanism for dissemination of new research findings, stimulation of fresh ideas and formation of unexpected research collaborations. This is particularly true in a multidisciplinary research environment like the Australian Key Centre for Microscopy and Microanalysis. The Key Centre invites presentations from leading researchers, from a wide variety of fields, around the world. The diverse staff and user-base of the Centre means that these talks often catalyse interdisciplinary collaborations. The seminar series also provides a forum for young, rising researchers to share their research.

Building Parameters to Meet the Ambient Needs of Aberration-corrected, High-resolution Transmission Electron Microscopes
Mike E. Lee and Jan H. Neethling, Physics Department, Nelson Mandela Metropolitan University, Port Elizabeth, South Africa
Wednesday, 4 November 2009, 10:00–11:00 am, room 236, Madsen Building F09, Electron Microscope Unit
The improvement of the spatial resolution for transmission electron microscopes (TEMs) and scanning electron microscopes (SEMs) has resulted in the increased sensitivity of these instruments to the ambient conditions. More recently, the introduction of aberration-corrected (Cs-corrected), high-resolution TEMs (HRTEMs) with sub-Ångström resolution has resulted in the need to construct purpose built facilities for these instruments. The ambient conditions which will critically influence the performance of the HRTEM include parameters such as vibrations (vertical and horizontal, frequency and amplitude), magnetic fields (AC and DC), air flow and temperature, electrical stability and ground loops. In this paper we will firstly discuss the origin of these parameters (external and internal) and their influence on the performance of the HRTEM. Secondly, the building design factors which will minimise the adverse ambient conditions will also be discussed as part of the design process for the HRTEM building at our institution in South Africa.
