CARBON WIRE HEATING DUE TO SCATTERING IN THE SNS

In the SNS, the 2.5 MeV H- beam from the RFQ will be accelerated in the Linac to 1 GeV, and then injected into the High Energy Beam Transport (HEBT). After passing through HEBT, the electrons are stripped during injection into the Accumulator Ring. The proton beam will be accumulated in the Ring for around 1000 turns before ejecting to the Ring to Target Beam Transport (RTBT). The filling time of the Ring will be 1 ms and the extraction pulse length from the ring will be 695 ns, with a repetition rate of 60 Hz. The baseline power per pulse of the proton beam is 1 MW, with the possibility of a 2 MW upgrade. Carbon wires will be used to measure beam profiles throughout the facility. Wire heating due to beam scattering by the carbon wires has been analyzed from the RFQ through to the RTBT. We present results from this analysis
