Annual Report 1996
Dr. Martin Edmund Sevior 

Teaching for 1996 
• Lectured the course 640-009 Medical Physics A. 

• Lectured the course 640-363 Particle Physics. 

• Lectured the course 640-354 Nuclear Physics. 

• Responsible for Lecture demonstrations. 

• Responsible for 2nd Year lab Optics development. 

Research for 1996 
• Leader of the project “Threshold measurements of the and reactions and chiral symmetry.” The analysis of the data from this TRIUMF experiment to make the world’s best measurements for these reactions was completed in 1996. 

• I am co-spokesman for TRIUMF experiment E719 “Search for the d’ dibaryon”. This experiment collected data in 1996. I was responsible for directing part of the data analysis for the experiment. 

• I am spokesman for TRIUMF experiment E781 “Investigations of the  p.p.   invariant mass distributions of Nuclear ( p.+,p.+p.- ) reactions with the CHAOS detector.” Approved by TRIUMF EEC at medium priority in 1996. 

• I am co-spokesman for TRIUMF experiment E778 “ p.▒. p Differential Cross Sections in the Coulomb-Nuclear Interference Region.” Approved by TRIUMF EEC at high priority in 1996. 

• Supervised Caroline Poulsen in her Ph. D. topic “Investigation of like-sign dilepton production at NOMAD”. The focus of this research project has narrowed to measuring the branching ratio for D0  «.k0 p.- ╡.+ n.╡. . This work is almost completed. 

• Supervised Ivan Williams research into high quality dosimetry for radiation therapy. 

• Supervised Yutaka Shoji’s Masters research project into the use of the reaction  19 F(n, a. ) 16 N as a means of producing high energy electrons. This project has gone some way to completing its goal of the development a novel high energy electron source.
