Abstract

The tandem accelerator of the Nuclear Structure Facility has been in regular scheduled operation for just over two years at voltages up to 20 MV and with a variety of accelerated ions ranging from hydrogen to iodine.

Operation of the machine is described and the performance of the various components including ion sources for radioactive as well as stable ion species and gas and foil strippers is discussed. Beam optics and beam transmission improvements are described.

An analysis is made of the main factors which are at present limiting the performance and efficiency of the machine. Critical components are identified and improvements to these components are described.

A brief description is given of the experimental areas and of new equipment to be commissioned in the near future.

Corona gradient distribution system variations and homogenization
1988, Nuclear Inst. and Methods in Physics Research, A
The corona current at 5 kV in air was measured for all tube point assemblies in the 14UD at Canberra. Variations in current of plus and minus a factor of three to four were found which imply voltage variations for fixed current of plus and minus 0.6 to 0.8 of the average voltage. Variations were worst at the tube ends, the sites of the major electron suppression fields. All extreme assemblies were regapped to homogenize the gradient. The consistency of the gradient over several months was also monitored and found to be within the intrinsic distribution.
Microsecond mass separation of heavy compound nucleus residues using the Daresbury recoil separator
1988, Nuclear Inst. and Methods in Physics Research, A
The recoil separator at the Daresbury Laboratory is described. An efficient charged particle beam transport system is combined with Wien filters to select heavy ions within a small velocity range at angles around 0° which have been produced by heavy ion induced reactions. The system separates and refocusses particles with a given mass to charge ( $A Q$ ) ratio. Resolution in $A Q$ is 1 in 300. The time taken to determine the atomic mass A and atomic number Z of an individual nucleus passing through the recoil separator is about 10⁻⁶ s. This is fast enough for phenomena associated with the compound nucleus decay to be electronically tagged according to the nuclear species produced. An example using γ-ray detectors around the compound nucleus formation target is given.
