Acceleration of polarized protons in the energy range of 5 to 25 GeV is particularly difficult: the depolarizing resonances are strong enough to cause significant depolarization but full Siberian snakes cause intolerably large orbit excursions and are not feasible in the AGS since straight sections are too short. Recently, two helical partial snakes with double pitch design have been built and installed in the AGS. With careful setup of optics at injection and along the ramp, this combination can eliminate the intrinsic and imperfection depolarizing resonances encountered during acceleration. This paper presents the accelerator setup and preliminary results.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

This grant covered an umbrella program of research in high-­‐energy particle physics at Southern Methodist University during the period 2004-­‐2013. The experimental program evolved during that time. At its early stages it included research on the CLEO experiment at CESR (Coan, Stroynowski, Ye), D0 experiment at Tevatron (Kehoe), preparation for the BTEV experiment at Fermilab (Coan) and construction and commissioning of the Liquid Argon Calorimeter for the ATLAS experiment at LHC (Stroynowski, Ye). In the last three years the program concentrated on the ATLAS experiment at LHC (Kehoe, Sekula, Stroynowski, Ye), D0 experiment at Tevatron (Kehoe) and NOvA experiment at Fermilab (Coan). Professor Sekula had a short-­‐term independent grant for which he is submitting a separate report. The theoretical physics program included work on non-­‐perturbative methods in the light cone representation (McCartor (deceased)), lattice calculations (Hornbostel), and determination of parton distribution functions (Olness). A summary of the accomplishments emphasizing results from the past three years is provided separately for each of the tasks.
