MCC Beam Parameter Table
Beam Parameters
| Energy | 1–11 GeV |
| Spread | (1–5)E-4 (energy dependent, see MCC link above) |
| Current | 1–120 µA |
| Emittance | 2E-9 mrad |
| Spot Size | 300 µm |
Beam Diagnostic Elements
| Beam Position Monitors | Transmission Line BPM (M15) with SE electronics. Resolution ≈ 20 µm at I ≈ 10 uA |
| Beam Current Monitors | 1 Unser (PCT) monitor with absolute accuracy of ±300 nA. Two RF cavity monitors tuned to 1.497 GHz with linearity of <0.5% |
| SuperHarps | Destructive wire scanner; good for emittance measurements. |
Beam Polarimeters
| Moller Polarimeter | Uses Moller scattering of the electron beam off electrons in a thin magnetized iron target. Moller polarimeters are mostly useful for low to mediem energies and low beam intensity. |
| Compton Polarimeter | Uses Compton scattering (e-ɣ), where the electron beam is sent through a magnetic chicane and scattered from a photon beam. Compton polarimeters are mostly useful for medium to high energies and high beam intensity. |
