SUMMARY:DETERMINING THE EJECTION RATE AND ENERGY SPECTRUM OF PROTONS AFTER 
	MUONIC CAPTURE ON ALUMINUM
DESCRIPTION:Featuring John Quirk\n\nPart of the Departmental Seminars.\n\nD
	issertation Committee:  James Miller\, Robert Carey\, Shyam Erramilli\, Mar
	tin Schmaltz\, Chris Grant\n\nAbstract:\n\nObservation of neutrinoless muon
	-to-electron conversion in the presence of a nucleus would be unambiguous e
	vidence of physics Beyond the Standard Model. Two experiments\, COMET at J-
	PARC and Mu2e at Fermilab\, will search for this process in the next few ye
	ars. 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 spectr
	a from muonic interactions in a number of materials. As a major source of d
	amage and background hits in COMET/Mu2e detectors\, AlCap measured the char
	ged particle and neutron spectra following nuclear capture on the candidate
	 target materials aluminum and titanium\, as well as in a number of structu
	ral and shielding materials capable of producing other backgrounds. Additio
	nally\, COMET/Mu2e are exploring schemes for determining the number of muon
	 stops via AlCap’s measurement of the photon spectra following both atomi
	c and nuclear capture. AlCap performed three data-taking campaigns between 
	2013 and 2015 at the Paul Scherrer Institut in Switzerland\, each geared to
	wards different measurements\, of photon\, neutron\, and charged particle e
	mission due to interactions of muons stopping in materials. During the fina
	l campaign\, AlCap collected heavy charged particle data. I will present an
	 overview of the Mu2e experiment\, and a summary of the experimental setups
	 and performances during the AlCap campaigns. My preliminary results of the
	 proton emission spectrum from the most recent campaign will be presented a
	nd compared to the results of previous and current parallel analyses\, as w
	ell as the impact on Mu2e.
