Present Status of KEK Isotope Separation System

The Present Status of the Jaeri/kek Joint Project for High-intensity Proton Accelerators

The high-intensity proton accelerator facility in Japan comprising a 600-MeV linac, a 3-GeV rapid-cycling synchrotron, and a 50-GeV synchrotron, has been officially approved for the construction of its Phase I. The Phase I includes the 1-MW pulsed spallation neutron source, but the 50-GeV ring can be operated up to only 30 GeV. The linac energy is limited to 400 MeV, which is not high enough fo...

Isotope Effects, Isotope Separation and Isotope Fractionation

Electrochemical isotope effect and lithium isotope separation.

A large electrochemical isotopic effect is observed upon the electrodeposition of lithium from solutions of propylene carbonate producing isotopically light metal deposits. The magnitude of fractionation is controlled by the applied overpotential and is largest close to equilibrium. Calculated partition function ratios for tetrahedrally coordinated lithium complexes and metallic lithium predict...

Laser isotope separation of uranium

A research effort was carried out at the Bhabha Atomic Research Centre (BARC), Mumbai, for developing laser-based techniques for enrichment of natural uranium to reactor-grade (2.5% to 3.0% U), with the potential to be economically scalable to industrial production. Three approaches – two molecular, namely CO2 laser-based approach and UF6-based approach, and one atomic, namely Atomic Vapour Las...

The status of the control system of the KEK accelerator test facility

Beam Commissioning for the damping ring of the KEK accelerator test facility (ATF) has been started since January 1997. Control system of the ATF accelerator i s based on the CAMAC-enhanced byte-serial highways handled by the Open-VMS Cluster system. Control software is integrated by using a commercial database application for process control. In this paper we present the status of the ATF cont...
