NASA Scientific and Technical Aerospace Reports

synchrotron phase (SPD), and fast phase error (FPERR), provide consistent information on the energy match and can be used
for an injection match tuning.

The Sudbury Neutrino Observatory (SNO) is an underground heavy water Cherenkov detector for studying solar
neutrinos. SNO is capable of performing both flavor sensitive and flavor blind measurements of the solar neutrino flux. The
first charged current (CC) measurement is found to be:(psi)(sub SNO)(sup CC)((nu)(sub e))= 1.75(+-) 0.07(stat.)(sub
-0.11)(sup+0. 12)(sys.)(+-) 0.05 (theor.) x 10(sup 6) cm(sup -2)s(sup -1) and the elastic scattering fluxes (ES) is:(psi)(sub
SNO)(sup ES)((nu)(sub x))= 2.39(+-) 0.34(stat.)(sub -0. 14)(sup+0.16) (sys.) x 10(sup 6) cm(sup -2)s(sup -1). The(psi)(sub
SNO)(sup CC)((nu)(sub e)) result, when combined with the high statistics elastic scattering (ES) measurement from
Super-Kamiokande, provide a strong evidence for solar neutrino flavor transformation (3.3(sigma)). The deduced total solar
neutrino flux is in good agreement with standard solar model predictions. No significant distortion in the energy spectrum is
observed.

A new test stand for testing LHC interaction region (IR) quadrupole magnets at the Fermilab Magnet Test Facility has
been designed and operated. The test stand uses a double bath system with a lambda plate to provide the magnet with a
stagnant bath of pressurized He II at 1.9 K and 0.13 MPa. A cryostated magnet 0.91 m in diameter and up to 13 m in length
can be accommodated. This paper describes the system design and operation. Issues related to both 4.5 K and 1.9 K operations
and magnet quenching are highlighted. An overview of the data acquisition and cryogenics controls systems is also included.

Report No.(s): DE2004-821068; ANL-AFCI-091; No Copyright; Avail: National Technical Information Service (NTIS)
This report deals with the validation of an ADS dynamic behavior through the TRADE program. We first describe the
motivations behind the TRADE project. This includes the types of ADS experiments to be performed and their necessity, beam
trips issues, representativity of the experiment, and steps to be taken in the validation procedure. Then we perform the
characterization of the TRADE core using deterministic methods. The general core description is given. A number of results
related to the core criticality and modeling with different geometries are presented. Finally we report the experimental results
of the recent critical measurements including the control rod calibration, determination of the critical configurations and fluxes
in the core.
