Instrumentation Developments and Beam Studies for the Fermilab Proton Improvement Plan LINAC Upgrade and New RFQ Front-End

Fermilab is developing a Proton Improvement Plan (PIP) to increase throughput of its proton source. The plan addresses hardware modifications to increase repetition rate and improve beam loss while ensuring viable operation of the proton source through 2025. The first phase of the PIP will enable the Fermilab proton source to deliver 1.8e17 protons per hour by mid-2013. As part of this initial upgrade, Fermilab plans to install a new front-end consisting of dual H- ion sources and a 201 MHz pulsed RFQ. This paper will present beam studies measurements of this new front-end and discuss new beam instrumentation upgrades for the Fermilab linac.

Transverse beam shape measurements of intense proton beams using optical transition radiation

A number of particle physics experiments are being proposed as part of the Department of Energy HEP Intensity Frontier. Many of these experiments will utilize megawatt level proton beams onto targets to form secondary beams of muons, kaons and neutrinos. These experiments require transverse size measurements of the incident proton beam onto target for each beam spill. Because of the high power levels, most beam intercepting profiling techniques will not work at full beam intensity. The possibility of utilizing optical transition radiation (OTR) for high intensity proton beam profiling is discussed. In addition, previous measurements of OTR beam profiles from the NuMI beamline are presented.
