Abstract

A fusion-product source, utilizing a 150 kV Cockraft-Walton linear accelerator, has been refurbished to provide a reliable nuclear diagnostic development tool to the national inertial confinement fusion (ICF) research program. The accelerator is capable of routinely generating DD reaction rates at approximately 10(7)/s when using a 150 kV, 150 microA deuterium (D) beam onto an erbium (Er) or titanium (Ti) target doped with D, and D(3)He reaction rates at approximately 5 x 10(5)/s when using a using a 120 kV, approximately 100 microA D beam onto a Er or Ti target doped with (3)He. The new accelerator is currently being used in a number of projects related to the national ICF program at the OMEGA Laser Fusion Facility [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)], which includes the wedge range filter charged-particle spectrometry program [F. H. Seguin et al., Rev. Sci Instrum. 75, 3520 (2004)] and the magnetic recoil neutron spectrometer [J. A. Frenje et al., Rev. Sci. Instrum. 72, 854 (2001)].

摘要

一个利用150 kV考克饶夫-瓦尔顿线性加速器的聚变产物源已进行翻新，为国家惯性约束聚变（ICF）研究计划提供一个可靠的核诊断开发工具。当使用150 kV、150 μA的氘（D）束轰击掺杂有D的铒（Er）或钛（Ti）靶时，该加速器能够常规产生约10(7)/秒的DD反应率；当使用120 kV、约100 μA的D束轰击掺杂有(3)He的Er或Ti靶时，能够产生约5×10(5)/秒的D(3)He反应率。这台新加速器目前正在用于与欧米茄激光聚变设施[TR·博埃利等人，《光学通讯》133, 495(1997)]的国家ICF计划相关的多个项目中，其中包括楔形范围滤波器带电粒子能谱测量计划[FH·塞金等人，《科学仪器评论》75, 3520(2004)]和磁反冲中子谱仪[JA·弗雷涅等人，《科学仪器评论》72, 854(2001)]。
