A Liquid Hydrogen Target for the Precision Measurement of the Weak Mixing Angle in Møller Scattering at SLAC
AbstractA 150 cm long liquid hydrogen target has been built for the SLAC End Station A E-158 experiment. The target loop volume is 55 liters, an the maximum target heat load deposited by the electron beam is ~700 W. The liquid hydrogen density fluctuation with full beam current (120 Hz repetition rate, 6 × 1111 electrons/spill) on target is at the 10-5 level, which fulfills the requirement for a precision measurement of the weak mixing angle in the polarized electron-electron scattering process.

NotesThe PDF file can be best viewed using Adobe Reader 4.9 or greater.
The PDF version of this document was distilled from a PostScript file most likely created from LaTeX source which used Type 3 fonts. The resultant PDF may be unreadable on the screen at the default viewing magnification (fonts will appear bitmapped, jagged), though the type will be legible at higher magnifications.
Despite the cosmetic problems resulting from the use Type 3 fonts in the original source file, such PDF files print without problems; likewise, the onscreen text is searchable and selectable.
