The production and anatomy of a tungsten powder jet

A tungsten powder jet is a potential candidate technology for a particle production target in a future high power (i.e. Multi-MW) particle accelerator based facility, such as a so-called conventional neutrino Super Beam, a proposed Neutrino Factory, or a future neutron source. To test the viability of producing a suitable powder jet a few simple experiments were performed using standard pneumatic conveying equipment and the encouraging results are presented.

Graphical abstractThis paper describes some preliminary studies of the production of a horizontal jet of powdered tungsten undertaken to investigate the viability of such a jet for use as a beam target in a high power particle accelerator (The Neutrino Factory Project).Figure optionsDownload full-size imageDownload as PowerPoint slideUnstable tungsten powder jet leaving a 20 mm ID cylindrical nozzle
