Injection Carbon Stripping Foil Issues in the Sns Accumulator Ring*

چکیده

We are reporting the results of studies on issues related to the injection stripping foil in the Spallation Neutron Source (SNS) accumulator ring. The problems related to foil heating and foil lifetime, such as current density distribution and temperature distribution in the foil, are investigated. The impact of injection errors on the beam losses at the foil is studied. The particle traversal rate and the beam losses due to scattering in the foil are summarized. Finally, SNS end-to-end simulation results of the foil-missing rate, the foil-hitting rate and the maximum foil temperature are presented.

Simulation of the Accumulation Process in the Itep Twac Storage Ring

Fully stripped heavy ion beam of a nearly relativistic energy and a super high intensity is supposed to be accumulated in the storage ring of ITEP-TWAC Facility that is under construction at ITEP on the base of existing accelerators. Nonliouvillean multiturn injection technique is elaborated to store in the accumulator ring as much as one thousand batches, which are accelerated in the booster s...

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 o...

Lorentz Laser-Assisted Stripping (Lolas) for H/H Injection into Proton Drivers

We discuss the main components of schemes for Lorentz laser-assisted stripping (abbreviated Lolas henceforth) proposed for injection into proton driver accumulators: H → H + e Lorentz stripping, H→H(n) laser excitation, H(n)→p + e Lorentz stripping. We mention results obtained in practice of H beam transport and storage and of experiments addressing physics of the H ion, of the H atom and of va...
