AMS Systems
The first compact AMS system based on the 500 keV Pelletron tandem accelerator has been shipped and accepted at the Center for Applied Isotope Studies. This system is equipped with the 134 sample multi-cathode SNICS source for high throughput. The system had a guarantee of 0.5% precision. However, 0.3% precision was exceeded in most cases. This is a carbon only system based on the work done at ETH/PSI in Zurich.
Last December, we accepted an order for a second compact AMS system for Adam Mickiewciz University in Poznan, Poland. The ship date is scheduled for October, 2001.
A versatile, 3 MV Pelletron tandem based AMS system is nearing completion on-site at the Institute for Applied Accelerator Analysis in Kanagawa, Japan. This system is also equipped with the 134 sample MC-SNICS for both high throughput and high precision.
Also last December, an order was accepted for a 5 MV Pelletron tandem based AMS system for the Scottish Universities Environmental Research Center near Glasgow. This system is designed for AMS applications involving a wide variety of isotopes including chlorine. The ship date is schedule for April, 2002.
These systems bring the total number of dedicated AMS Pelletron systems to ten with an additional twelve Pelletron systems being used for AMS for a significant amount of their beam time.
PIXE and RBS
Presently in manufacture is a 3 MV single-ended Pelletron for the Guelph Scanning Proton Microprobe Laboratory at the University of Guelph. This is the group, under the direction of Professor J.L. Campbell that developed the PIXE analysis software GUPIX. This systems is scheduled for shipment in July, 2001.
A 1.7 MV Pelletron tandem equipped with the Model RC43 analysis endstation is presently in manufacture for the University of Durham in the U.K. This complete RBS system will be under the direction of Professor Randal W. Richards at the Interdisciplinary Research Centre in Polymer Science. It is scheduled for shipment in October, 2001.
Earlier this month a small ion beam system capable of positive hydrogen ions and negative hydrogen ions was shipped to the Marshall Space Flight Center in Alabama. It will be used for testing an antimatter trap experiment.
Over the years, NEC has converted a number of the older style rubber belt Van de Graaffs to the Pelletron charging system. Recently, the Model FN in the Physics Department at the University of Notre Dame Nuclear Structure Laboratory was converted and accepted. Presently in manufacture is an EN conversion for the Rafter Radiocarbon Laboratory at the Institute of Geological and Nuclear Sciences in New Zealand. It is scheduled for shipment near the end of April, 2001.
These conversion will bring the total number of FN’s converted to ten and the Rafter EN will be the fourth EN converted. These conversions result in less maintenance and greater terminal voltage stability.
