25 years ago, the Berlin low-temperature groups at the Physikalisch-Technische Bundesanstalt (PTB), the Hahn-Meitner Institute and the Freie Universität initiated the Berlin Low-Temperature Colloquium to strengthen their collaboration and to discuss new developments and trends in low-temperature physics and cryogenic techniques. Several workshops have been held in the framework of this colloquium bringing together experts from academic institutes, universities and industrial companies active in the fields of low-temperature physics and metrology.
Following the low-temperature physics and metrology symposia held by PTB and the Helmholtz Zentrum Berlin HZB (founded by merging the former Hahn-Meitner Institute and BESSY) in May 2007 and December 2009, this workshop is dedicated to this anniversary.
Meanwhile, the European Microkelvin Collaboration, a project funded by the European Commission which was introduced in the 2009 workshop by its coor-dinator Mikko Paalanen, is in its final stages and the workshop will give an opportunity to review and disseminate results obtained so far and to discuss the activities towards creating an integrated European virtual laboratory in microkelvin physics and technology.
This workshop is intended to initiate discussions and networking activities within the European low-temperature community and to identify future demands on low-temperature metrology.
Cooling techniques Thermometry Sensors Quantum gases, fluids and solids Magnetism and properties of solids Quantum electron transport Superconductivity
Presentations will be given as talks and posters.
If you would like to give a presentation at the workshop, please submit a brief summary to margit.kleinsorge@ptb.de.
Deadline for contributions: 23 November 2012.
In conjunction with the workshop we invite companies concerned with the field of low-temperature technology to exhibit their product portfolio. Please contact the workshop office for more information.
Workshop starts on Thursday at noon Social gathering on Thursday evening Presentations continue on Friday For those interested in a lab tour and further discussions, PTB colleagues are available on Friday
The workshop is organized by the Physikalisch-Technische Bundesanstalt (PTB), Germany's National Metrology Institute, and the Helmholtz Zentrum Berlin. It takes place at the historical PTB campus which is located within walking distance of the Kurfürstendamm, a well-known shopping street in central Berlin, and the station Zoologischer Garten, right in the heart of Berlin's “City West”.
