Experimental Runs

Muonic hydrogen research at TRIUMF has evolved for over a decade, making continual progress in improving the measurements and understanding the physics. Of nearly a dozen series of experimental runs performed up to now by the Collaboration, some of which have or will have resulted in Master's, as well as Ph.D. theses [179,30,199,203], the runs analyzed for this thesis are the first two with tritium used in the target, which are summarized in Table 4.1.

¹ See Section 3.2.2 the for description of diffusers.

² Each detector had a Cu collimator with an opening of 13.9 mm$\times$50 mm.
