Development of radioactive beams at LAMPF for a high precision test of the standard model and as a step towards an IsoSpin Laboratory

PDF Version Also Available for Download.

Description

This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Producing high yields of isotopically pure beams of radioactive heavy ions is the technical challenge facing the IsoSpin Laboratory (ISL). The main objective of this project is to design, fabricate, install, and make operational a thin-target, He- jet system at LAMPF to provide high-intensity {sup 125-139}Cs isotopes for an atomic parity nonconservation (PNC) experiment and as a robust production source for radioactive beams. The Cs-PNC experiment itself would take several years beyond the successful completion of the developments outlined ... continued below

Description

This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Producing high yields of isotopically pure beams of radioactive heavy ions is the technical challenge facing the IsoSpin Laboratory (ISL). The main objective of this project is to design, fabricate, install, and make operational a thin-target, He- jet system at LAMPF to provide high-intensity {sup 125-139}Cs isotopes for an atomic parity nonconservation (PNC) experiment and as a robust production source for radioactive beams. The Cs-PNC experiment itself would take several years beyond the successful completion of the developments outlined in this project. The experiment outlined in this project. The experiment seeks to measure the 6S-7S PNC transition rate for this series of Cs isotopes. From the ratios of these rates measured in the different isotopes, a fundamental test of the standard model can be made at the level of 0. 2{percent}. Herein, we describe the successful operation of a thin- target, He-jet system operating at primary beam intensities of up to 700 {mu}A with production yields of 10{sup 7} to 10{sup 8} atoms/s for a wide range of nonvolatile and Cs radioisotopes. 7 refs., 3 figs.
