    keyword=BPM/BCM Tests and Commissioning for G2P.

    PM

    First test + commissioning of Hall A G2P BPM system. Figure 1 is pulse beam to hall, with subsequent steering to trip ion chambers.

    Figure 2 is the fast raster at ~ 2uA (demonstrating signal analysis capability). Rx BW = 22kHz.

    Figure 3 is the BCM settings (preliminary) for 1 uA CW F.S. Hall A personnel will tweak as needed. For now, 60,000 cts = 1 uA. We see a noise floor of ~400 cts, rms. This results in an expected detection limit of ~ 7nA for these settings. Figure 4 shows 0-1uA current ramp.

    Target and SL 24 problems. We'll do more when beam restores.
