  2. Problem: What are the signals to be readout from the LTA? • Beam Line (Carol Johnstone) • Beam Properties Measurements (CJ) • Cryogenics (Barry Norris) • A. H2 • B. He • Experiment • A. Absorbers (Mary Anne Cummings, Edgar Black) • B. RF Cavities (Al Moretti) • C. Solenoid (Al Moretti)

  3. Beam Line Elements # signals • 750 KeV Chopper 1 • dipole magnets currents 5 • quad magnet currents 13 • stripping foil 1 • collimater positions - 2 units 8 • ion chamber 1 (in front of beam dump)

  4. Beam Properties Measurements # signals • Tune Parameters ? data set • Beam Position Monitors 20-40 • Toroid Beam Current Monitor 1 (slow response) • Fast Beam Current Monitor 1 (fast response) • Beam Loss Monitors 5-10
