A compact tritium AMS system

Advanced Tritium Recovery System

LLE Review, Volume 89 25 Introduction As part of the U.S. Inertial Confinement Fusion Program, LLE plans to implode deuterium–tritium (DT)–charged microspheres. These microspheres are filled with high-pressure deuterium and tritium gas under cryogenic conditions. The spheres are then stored and transferred as needed to the target chamber (located in an adjacent room) under vacuum and at tempera...

AMS - A Case-Based Service Support System

Compact Modeling of Emerging Technologies with VHDL-AMS

This paper deals with the compact modeling of several emerging technologies: first, the double-gate MOSFET (DG MOSFET), and second, the carbon nanotube field-effect transistor (CNTFET). For CNTFETs, we propose two compact models, the first one with a classical behavior (like MOSFET), and the second one with an ambipolar behavior (Schottky-barrier CNTFET). All the models have been compared with ...

The Ams Time of Flight System

The Time of Flight (TOF) system of the AMS experiment provides the fast trigger to the detector and measures the crossing particle direction, velocity and charge. AMS was operated aboard of the shuttle Discovery on June 1998 (NASA STS-91 mission) and will be upgraded and installed on the International Space Station at the end of 2003, for 3 years of data taking. The performances of the TOF duri...

A new bomb-combustion system for tritium extraction

Quantitative extraction of tritium from a sample matrix is critical to efficient measurement of the low-energy pure beta emitter. Oxidative pyrolysis using a tube furnace (Pyrolyser) has been adopted as an industry standard approach for the liberation of tritium (Warwick et al. in Anal Chim Acta 676:93-102, 2010) however pyrolysis of organic-rich materials can be problematic. Practically, the m...
