FY08 parameters for the injection, acceleration, and extraction of gold ions and deuterons in the booster, AGS, and RHIC

A Gold ion with charge eQ has N = 197 Nucleons, Z = 79 Protons, and (Z-Q) electrons. (Here Q is an integer and e is the charge of a single proton.) The mass is m = au - Qm{sub e} + E{sub b}/c{sup 2} (1) where a = 196.966552 is the relative atomic mass [1, 2] of the neutral Gold atom, u = 931.494013 MeV/c{sup 2} is the unified atomic mass unit [3], and m{sub e}c{sup 2} = .510998902 MeV is the electron mass [3]. E{sub b} is the binding energy of the Q electrons removed from the neutral Gold atom. This amounts to 0.332 MeV for the helium-like gold ion (Q = 77) and 0.517 MeV for the fully stripped ion. For the Au{sup 31+} ion we have E{sub b} = 13.5 keV. These numbers are given in Ref. [4]. The deuteron mass [3] is 1875.612762(75) MeV/c{sup 2}.

Condition of Texas Pavements: Pavement Management Information Systems Annual Report, 2008-2011 (open access)

Condition of Texas Pavements: Pavement Management Information Systems Annual Report, 2008-2011

Annual report describing the condition of Texas pavements based on distress ratings and ride quality measurements from the Pavement Management Information System (PMIS) during fiscal years 2008-2011. "The report includes the percentage of lane miles in 'Good' or better condition, trends for the major highway systems (IH, US, SH and FM) and pavement types (ACP, CRCP and JCP), trends for pavement distress types and maintenance level of service information" (p. ii).
