| Get and interpret data from survey. | Dave Kashy, S. Kuhn | ||
Target |
Fabricate and test backup Banjo windows | Dave Kashy | |
| Final improvements on sensors, controls and feedback loops | M. Seely, C. Keith | Dave Kashy | |
| Finalize µwave system (remote control, optimize parameters). Finalize LabVIEW programming. Write up operation procedures, training. | D. Crabb, M. Seely | Christiana Martin, Renee Hutchins, Raffaela Devita, ODU group | |
| Runplan | Simulation: Acceptances, reconstruction, resolution. Need to establish agreement with measured E1 data and then implement target field, position and materials. Main goals: simulated proton and deuteron inclusive spectra for dilution factor determination and radiative/resolution corrections. Study reconstruction for exclusive channels. | S. Kuhn | Dale Conwell
Junho Yun (ODU) Sebastian Kuhn |
| Determine count rates vs. Q2, W, E, B for H and Al from E1 run. Estimate nuclear effects from E2 results. Needed as input for previous item. Also study effects of different trigger thresholds/configurations. | S. Kuhn | Many E1 collaborators

| DAQ/Online | Read out BPM's, Beam scint.'s, Faraday cup scalers keyed to helicity changes every 2 seconds. Calibration raster magnets vs. BPMs using fast readout (add to event-by-event data stream). | Chip Piller, Arne Freyberger, Dieter Cords | Sergei Boiarinov, Tony Forest, Mehmet Bektasoglu |
| Online diagnostics and asymmetries; implement new target position + Bfield for online RECSIS (roads). | Sergei Boiarinov? | Tony Forest, Franz Klein | |
| Trigger: 2nd level, tight C*EGN(in)*EGN(out) plus several loose, prescaled ones. Push data rate! | Dave Doughty, online group | ||
Analysis |
Reconstruction (vertex, phi, theta, secondary particles, m.sc., radiation). False Asymmetries. Dead time effects. Trigger and detection/cut efficiencies. M.Sc. and secondaries from hits of structure. Physics (pion, charge symmetric) and other background (Møller). Dilution. Nuclear Effects. Radiative corrections. From asymmetries to g1 or A1. | Spokespersons | Spokespersons,
