SLAC E154 Target

Target Pictures and Drawings

• Picture of cells scanned at 150 dpi* and 300 dpi* respectively from Mike Romalis.
• SLAC Publications has made a color EPS drawing* of the target showing various coils and lasers.
• A similar diagram of E154 target with lasers, coils, etc* by Mike Romalis.
• There is also a schematic drawing* of the polarized Helium-3 target by Todd Smith.
• Or you may prefer the cartoon drawing* by MCC Operators.

Target Polarization Measurements

• He-3 and water NMR signals* with fits.
• Equipment setup* for detection of Electron Paramagnetic Resonance used for frequency shift polarimetry.
• Typical frequency shift data* with fit.
• A simple schematic showing how optical pumping* works.
• Data on pressure broadening* of Rb resonance lines used to determine He-3 density.
• Typical Spin-up* of Picard during the run with a fit.

Target Notes
