This page is currently under construction!Theoretical motivation for use of recoil proton polarimetry at electron accelerators arose in the 1980s. More will be written about this later.
S. Nanda was the CEBAF FPP contact staff member during the initial formulation of the project. The draft design for a Hall A FPP with wire chambers was done largely by J. M. Finn of College of William & Mary. This design is discussed in the CEBAF Hall A Conceptual Design Report, pages A7-13 to 16, 1990. A project to study the possible use of scintillating fiber technology was headed by C. Perdrisat of William & Mary, with help from S. Majewski and the detector group of CEBAF. The idea to use straws arose in discussions between F. Barbosa, S. Majewski, and S. Nanda of CEBAF and R. Gilman of Rutgers. Further discussions with Seogh Oh of Duke University were very helpful.
Initial prototyping and development tests were done at CEBAF in 1991 by Rutgers people R Gilman, Gerfried Kumbartzki, Qian Sun (UG), and Mahesh Yadav (G), aided by CEBAF people Sirish Nanda of Hall A, Brian Kross, Stan Majewski, and Randy Wojcik of the detector group, and Steve Christo of Hall B. Qian Sun also did much of the initial simulation coding. Fernando Barbosa of the electronics group provided several test straws and much helpful information. The collaboration thanks CEBAF for providing prototyping funds.
R. Gilman did the initial conceptual design for the straw chambers, based largely on the design of the Brookhaven EVA detector straws, and discussions with Fernando Barbosa of CEBAF, who had been involved in the EVA straw chamber construction. This system was proposed to the National Science Foundation for funding in 1992. C. Perdrisat of William & Mary was principle investgator (PI) of proposal PHY 9213864, which funded construction of the front chambers. R. Gilman of Rutgers was PI of proposal PHY 9213869, which funded construction of the rear chambers, and the carbon analyzer. C. Glashausser and R. Ransome of Rutgers were co PIs on the Rutgers grant. The collaboration thanks M Montag and Brookhaven National Laboratory for permission to use their mold for the construction of the gas caps.
The Rutgers faculty / staff involved in this project included Asso. Prof. Ronald Gilman, Prof. Charles Glashausser, Dr. Gerfried Kumbartzki, and Asso. Prof. Ronald Ransome. Their coworkers included visitors, postdocs, and many undergraduate and graduate students.
Louis Bimbot, from Orsay, worked primarily on the FPP while a visitor at Rutgers for two years. He was involved in the initial design and construction efforts, including setup of the clean room. Paul Rutt was the lead postdoc on the project, primarily responsible for many aspects of the construction at Rutgers. Ed Brash, worked with the Los Alamos chamber and, after moving to CEBAF, was responsible for the CEBAF software and contact with CEBAF.
Graduate students involved in the project included Sorin Bastea, Jeff Brusoe, Xiao-Qinq Wu, J Xiong, and Mahesh Yadav. David Beatty worked on the Los Alamos chamber as a graduate student, then later rejoined us to work on the CEBAF EPICS control software as a postdoc.
Warren Brown, a high school teacher from New Jersey, worked with the FPP group for two years, funded by Research Corporation Partners in Science grant HS0331.
Rutgers undergraduates involved in the project, and listed on grant reports, included the following: Joe Carraha, Ted Farnum, Keith Filarowitz, Nicola Guidara, Yilu He, Christopher Mauger, Dean Micale, ? Nielson, Peter Sotory, David Wolinski, and Yu Zhou. Rutgers undergraduates paid from the operating grant included: Mustafa Ali, Phil Black, Sita Chopra (short term), Ramu Gudapati, Matthew Hill, Mustafa Kapadia, Brian Kowiak, Norma Lucero, Brad Price, and Qian Sun. The Rutgers Work Study program paid Oleg Teytelboym and Polina Mednikova. REU students included Oskar Liivak and David Wolinski in 1992, and Matthew Hill and John Lissikatos in 1995. Both Brad Price and David Wolinski did seniors honors projects related to this work. Also ? Myrnyj worked on construction of the clean room.
