Title：Design of a Long Baseline Neutrino Experiment at BNL

Speaker：Dr. W. T. Weng，BNL

Moderator: Prof. QIN Qing

Time: 14:00, December 18, 2014

Place: Room C305

Abstract:

After a brief introduction of neutrino physics researches performed at BNL from 1962 to 2014, my role in the AGS Expt. 704 in 1977 on neutrino oscillation search by multi-turn fast extracting proton beam at 1.5 GeV will be described. The addition of AGS Booster in 1992 raised the AGS intensity to 7*10**(13) per pulse which allows the consideration of 1 MW beam from the AGS for long base line neutrino oscillation experiment to Homestead mine in South Dakota, 2,400 miles from BNL. If successful, the experiment can address the problems of both mass hierarchy and CP violation in neutrino sector.

The results of the study of “The AGS-Based Super Neutrino Beam Facility”, led by W. Marciano, M. Diwan and W. T. Weng performed in 2003 to 2006 at BNL, will be described. The design of the AGS complex for 1 MW operation and related accelerator improvement issues require the addition to the existing facility a new SPL of 1.0 GeV, increase rep rate of the AGS, and a new target and beam delivery system to Homestead.

At the end of my talk, the speaker will comment on my interactions with IHEP since 1979 and over the last 35 years which witnessed the dramatic growth of IHEP.
