Abstract

The neutron Fourier diffractometer FSS (Fourier Strain Scanner) was used between 1990 and 2010 at the FRG-1 stationary reactor at the GKSS research center (Geesthacht, Germany) for the study of residual stresses in structural materials and industrial products. In 2010, the FRG-1 reactor was finally decommissioned. In this regard, the FSS diffractometer was transported to the Frank Laboratory of Neutron Physics of JINR (Dubna, Russia) in 2014 and installed on channel no. 13 of the IBR-2 pulsed reactor. The results of upgrading the instrument and further prospects for its development are presented.

IBR-2 反应堆的中子傅里叶应力衍射仪 FSS：升级结果和进一步发展前景

摘要

中子傅里叶衍射仪 FSS（傅里叶应变扫描仪）于 1990 年至 2010 年间在 GKSS 研究中心（德国 Geesthacht）的 FRG-1 固定反应堆中用于研究结构材料和工业产品中的残余应力。2010 年，FRG-1 反应堆终于退役。对此，FSS衍射仪于2014年运至JINR（俄罗斯杜布纳）中子物理弗兰克实验室，安装在1号通道。13 的 IBR-2 脉冲反应器。介绍了仪器升级的结果和进一步的发展前景。
