PM17 | Development of a Permanent Magnet Residual Gas Profile Monitor With Fast Readout | 134 |
|
||
Modern ion accelerators and storage rings require very fast beam profile measurements (turn-by-turn) with highest resolutions. We propose a new residual gas monitor, which will operate on secondary electrons whose trajectories are localized within ∅ 0.1 mm filaments along 0.1 T uniform magnetic field lines excited by a permanent magnet. The best way to adopt the resolution of 0.1 mm into the data acquisition system is the use of a CCD camera with upstream MCP-phosphor screen assembly. To realize a fast turn-by-turn beam profile measurement a photodiode readout by a 100-channel amplifier/digitizer is foreseen. |
