Presentation Transcript

  1. LIQUID METAL TARGET High Z metals planned to use, such as BiPb, Mercury. BiPb has melting temperature 154oC. Hg has boiling temperature 354oC Hg or BiPb Jet velocity~10m/s Profile of jet~ 1.5x4 mm2 Hg jet uses latent heat of vaporization Flange diameter 2¾” Calculations show absolute feasibility of this approach

  2. FULLY ASSEMBLED UNIT Cryo plumbing Lens with shield Hg or BiPb target unit Collimator Flange diameter 2 ¾ in

  3. MODELING OF PULSED HEATING As soon as the temperature profile is known, the thermal pressure pTcan be expressedwhere characterizing the ratio of the thermal pressure to the specific thermal energy called Grüneisen coefficient. Instant position of the bunch moving in the target, at the left (one frame from movie) Isotherms after the bunch passage, at the right.
