Example of Projects improved/ proposed for BNL also given:

Neutrino:  Dr. Parsa in 1998 started the Neutrino (v) Charge Parity violation (CPV) and extra Long Baseline (L, 2000 km < L < 4000 km) Neutrino (LBN) oscillation Physics and Experiment (LBNE) that envisioned sending very intense neutrino (ν) beam through the earth to a far away underground multipurpose large detector to search for Physics potentials for making precision measurements of all neutrino oscillation parameters, Proton decay and natural sources of neutrino; such as supernova. Very long distance (baseline) is the key to this approach, and provide possibility of observing multiple nodes of the neutrino oscillation probability in appearance and disappearance experiments. Observation of such a pattern will demonstrate oscillatory nature of the flavor changing phenomenon when studied at LBNE, and could provide e.g., information on inside of newly-formed neutron star, and possible observation of black hole formation... LBNE has been high priority fundamental Science project for over a dacade. [Protons from an accelerator e.g., BNL AGS, would hit a target (e.g., Mercury Jet), produce bursts of particles; pions decay to muons which decay to neutrinos π → μ ν; Neutrinos move on through air and earth to the detector direction]. In 2012 DOE approved LBNE with source at FNAL. Later LBNE was renamed DUNE. Member of LBNE and DUNE collaborations.

Ultra-Cold Muons:  Dr. Parsa in 2006, proposed an "Intense Muon Facility" For Multidisciplinary Research. Focus of her LDRD (Lab Director Research and Development) proposal was first to develop an intense source of muons, 10^12 µ± /sec, from the AGS (Alternating Gradient Synchrotron), that would span a broad spectrum of disciplines ranging from nano-technology to life sciences and medical diagnostics showing all of which can be researched using muons. And R & D directed toward the conceptual design of the intense muon research facility (that would address muon production, trapping and cooling). A major goal would be (a final focus device capable of) delivering Ultra-Cold Muons with better than nanometer spatial resolution to the experimental areas. Low energy, high intensity and outstanding resolution are the key features of the envisioned facility that allow novel applications, and scientific discoveries complementary to all BNL Facilities.

Muon Collider:   In 1990 Dr. Parsa started the Muon Collider Physics and Facility research at BNL, that by early 1993 led to "Muon Collider Collaboration" and grew for over a decade. A Muon collider accelerates subatomic particles called muons (μ), and makes them collide, to discover new subatomic forces and particles. Muons are 200 times heavier than electrons; have the same electric charge, emit less light (and lose less energy) than electrons when in circular motion. Smaller beamstrahlung and consequently smaller energy loss open possibility of more particle per bunch and higher luminosity. Small Muon rings for Higgs Factory and Neutrino Factory were also considered. After over a decade, several Proposals and Feasability studies by 2005 the lack of Muon Cooling technology etc., stopped/ postpone the building of μ Collider at BNL (in US). [Muon Collider start with proton accelerator that generate pions (π) from a target; proceeds through phase rotation, (π → μ ν) decay channel; muon cooling; acceleration; storage in collider ring and then to a detector].

Booster:  In 1985 Prof. Parsa joined the U.S. Department of Energy's Brookhaven National Laboratory (BNL). Shortly after she was invited on the new Booster Task force (to improve on earlier Booster accelerator design etc. that twice had failed the construction funding Reviews..). She established a compendium of computer codes and developed analytical formulas she used for Booster, SSC, etc. Dr. Parsa also was the Booster Configuration Manager and Editor of the Booster Design Manual that she completed, passed the Department of Energy's (DOE) funding Review and BNL Received funding in 1986, for Booster Construction. Her Formulations and papers has inclueded e.g., Analytical Method For Treatment of Nonlinear Resonances In Accelerators; Accelerator Dynamics and Beam Aperture; etc. Booster makes it possible for AGS to accelerate and deliver heavy ions into the RHIC (Relativistic Heavy Ion Collider). [Booster accelerates particles (e.g. Protons and Heavy Ions), inject them into the AGS that further accelerates and inject particles into the RHIC].

SSC:   Dr. Parsa developed formulations and codes used for the U.S. SSC (Superconducting Super Collider), e.g., her "Second Order Perturbation In SSC";  "Resonance Analysis For The SSC"; "Linear Aperture, Smear, Variation Of Particle Action And Beam Emittance In SSC"; "Chromatic Perturbation And Resonance Strength In SSC" etc. [SSC a U.S. Particle Collider under construction in Texas, was officially demised in 1993].

Neutrino Diagnostics:   Dr. Parsa has been Chief Scientist and U.S. Team Leader of the (State Department Funded) Projects with Former Nuclear Weapon Scientists from Russia, Ukraine (1999-2005) etc. E.g., one of her 2004 (STCU) proposal was on "Technique for Neutrino Diagnostics of the Fissile Materials in Nuclear Reactor", including antineutrino method of remote control and diagnostics of operating fast neutron reactor. [Antineutrino capture by protons (inverse beta decay) constitutes basis of the detector. By measuring energy of produced positrons, it is possible to reconstruct the antineutrino spectra.].

Professional Activities:   Professor Parsa in addition to Teaching and Research, has been: "Author"; "Referee"; "Editor" and "Editor in Chief" of scientific papers, Manuals, Newsletters, and books; Chief Scientist and Executive Science International LLC (2006- ); Member of professional organizations and collaborations. Has served as Chair, Coordinator, Developer and organizer of Research Programs and Workshops. Elected Member of Executive committee of American Physical Society NY State Section (2001-2005); Chairperson of biweekly BNL seminars 12 years (1987-1999). Elected Chair of: Digital Equipment Corporation User Society Upton Section (1986-1999) and BNL Computer Users Group 13 years; Member of Cyber Administration. etc.
