SUMMARY:Determining the Ejection Rate and Energy Spectrum of Protons after 
	Muonic Capture on Alumnium
DESCRIPTION:Featuring John Quirk\n\nPart of the PhD Final Oral Exams.\n\nDi
	ssertation Committee:  James Miller\, Robert Carey\, Shyam Erramilli\, Mart
	in Schmaltz\, Chris Grant\n\nAbstract:\n\nObservation of neutrinoless muon-
	to-electron conversion in the presence of a nucleus would be unambiguous ev
	idence of physics Beyond the Standard Model. Two experiments\, COMET at J-P
	ARC and Mu2e at Fermilab\, will search for this process in the next few yea
	rs. These experiments will provide upper-limits on this branching ratio up 
	to 10\,000 times better than previously published.\nCOMET/Mu2e developed a 
	joint venture\, the AlCap Experiment\, to measure particle emission spectra
	 from muonic interactions in a number of materials. As a major source of da
	mage and background hits in COMET/Mu2e detectors\, AlCap measured the charg
	ed particle and neutron spectra following nuclear capture on the candidate 
	target materials aluminum and titanium\, as well as in a number of structur
	al and shielding materials capable of producing other backgrounds. Addition
	ally\, COMET/Mu2e are exploring schemes for determining the number of muon 
	stops via AlCap’s measurement of the photon spectra following both atomic
	 and nuclear capture. AlCap performed three data-taking campaigns between 2
	013 and 2015 at the Paul Scherrer Institut in Switzerland\, each geared tow
	ards different measurements\, of photon\, neutron\, and charged particle em
	ission due to interactions of muons stopping in materials. During the final
	 campaign\, AlCap collected heavy charged particle data. In this thesis\, I
	 present a measurement of the proton emission spectrum from the most recent
	 campaign and compare with the results of previous and current parallel ana
	lyses. I also discuss the impact on Mu2e.
