Instruments and Methods: A Simple Thermal Ice Drill

Instruments and Methods Towards radiocarbon dating of ice cores

A recently developed dating method for glacier ice, based on the analysis of radiocarbon in carbonaceous aerosol particles, is thoroughly investigated. We discuss the potential of this method to achieve a reliable dating using examples from a midand a low-latitude ice core. Two series of samples from Colle Gnifetti (4450ma.s.l., Swiss Alps) and Nevado Illimani (6300ma.s.l., Bolivian Andes) demo...

Nuclear Instruments and Methods

Computational Physics Numerical modeling represents an important tool to fulfil the objectives of the group and two domains of application are presently covered: Calculation of radiation fields and Modelling of cold plasmas for material processing. Along with these applications, the group is also involved in improving the available computational capacity with the build up of a Beowulf cluster f...

Thermal Simulation and Experiment of Lunar Drill Bit in Vacuum

Drilling samples of lunar soil is an important and indispensable part of China’s lunar exploration project. The drill bit temperature during the drilling process is one of the key concerns for scholars, especially for the hard lunar rock drilling in vacuum. In this article, the simulation analysis of drilling in atmosphere and vacuum is conducted. Moreover, a fiber grating temperature measuring...

The Chronos Thermal Drill and Sample Handling Technology

Nuclear Instruments and Methods in

In digital X-ray sensors, pixel complexity is limited by the instabilities of amorphous silicon transistors or by the lack of homogeneity of their polycrystalline silicon counterparts. Here, we present a novel approach to the fabrication of thin-film transistors, based on the use of silicon nanowires grown in porous alumina templates. Transistors made from silicon nanowires are essentially stud...
