摘要

TRIUMF BL1B中子和质子设施已经升级，改进了中子生产转换器的屏蔽，以提供更高的中子强度。该设备既可以提供用于设备测试的准直波束，也可以提供用于系统测试的大面积波束。FLUKA计算优化了屏蔽效果，确定了中子能谱和横向剖面。通过活化测量来确定不同位置的中子通量。

Intensity Upgrade to the TRIUMF 500 MeV Large-Area Neutron Beam

The TRIUMF BL1B neutron and proton facility has been upgraded with improved shielding of the neutron-production converter to provide higher neutron intensities. The facility can provide both collimated beams for device testing and large-area beams for systems testing. FLUKA calculations were performed to optimize the shielding and to determine the neutron energy spectrum and transverse profiles. Activation measurements were done to confirm the neutron flux at different positions.
