Flowing Tungsten Powder for Possible Use as the Primary Target at a Muon Collider Source
نویسندگان
چکیده
The use of a liquid metal jet [1] as the primary target at a muon collider source is not yet an established technique. Among possible alternatives, we are investigating the use of a jet of tungsten powder. We first considered metal-powder slurries, based on the example of a commercial zinc paint with density 3 g/cm. For a muon collider target, both high atomic number and high density are desirable. Both tungsten and tungsten carbide powders are readily, and are apparently used in slurries in some industrial applications. After a somewhat negative experience with slurries, we investigated dry powder, following a suggestion by Colin Johnson at the Targetry Mini Workshop in Princeton, Feb. 28, 1998. Better success was achieved, as reported below, but much work is still needed before a powder target would be a viable option for the primary target

Carbon and Mercury Target Systems for Muon Colliders and Neutrino Factories*
A high-power target is required to convert a powerful MW-class proton beam into an intense muon source or neutrino source in support of physics at the intensity frontier. The first phase of a Muon Collider or Neutrino Factory program may use a 6.75-GeV proton driver with beam power of only 1 MW. At this lower power it is favorable to use a graphite target with beam and target tilted slightly to...
متن کاملThe Potential of Fluidised Powder Target Technology in High Power Accelerator Facilities
This paper describes the potential of fluidised powdered material for use as a particle production target in high power particle accelerator based facilities. In such facilities a multi-MW proton beam is required to interact with a dense target material in order to produce subatomic particles, e.g. neutrons for a neutron source or pions for a so-called conventional neutrino beam, a neutrino fac...
متن کاملTarget Options and Yields for a Muon Collider Source
Efficient production and collection of a large number of muons is needed to make a muon collider viable. Target options are considered to maximize pion yield and to provide target survivability for 8 and 30 GeV primary beams of approximately 10 protons per pulse at 15 Hz. Realistic Monte-Carlo simulations are performed for targets of different configurations and dimensions in a high-field solen...

One very important problem of future high-power colliders, such as the muon collider, is to create an effective and reliable target system that is able to withstand a harsh environment and generate effective high-flux muon beams. Liquid metal jets (pulsed or continuous) are proposed as potential target candidates. Such a proposal poses two critical problems: penetration of a free liquid jet ins...

An update is presented on a conceptual design for a pion production target station using a rotating cupronickel band and that was originally proposed for use at a muon collider facility with a 4 MW pulsed proton beam. After reviewing the salient design features and motivations for this target, ongoing studies are described that are attempting to benchmark the thermal stresses and radiation dama...
