【 摘 要 】

New methods for generating ??????Mo are being explored in an effort to eliminate proliferation issues and provide a domestic supply of ??????mTc for medical imaging. Electron accelerating technology is used by sending an electron beam through a series of ????��??��Mo targets. During this process a large amount of heat is created, which directly affects the operating temperature set for the system. In order to maintain the required temperature range, helium gas is used to serve as a cooling agent that flows through narrow channels between the target disks. Currently we are tailoring the cooling channel entrance and exits to decrease the pressure drop through the targets. Currently all hardware has be procured and manufactured to conduct flow measurements and visualization via solid particle seeder. Pressure drop will be studied as a function of mass flow and diffuser angle. The results from these experiments will help in determining target cooling geometry and validate CFD code results.
