PPT-8th DITANET Topical Workshop on Beam Position Monitors, 16-

1 BPM Signal Processing with Diode Detectors Marek Gasior Beam Instrumentation Group CERN Outline Why using diode detectors for processing BPM signals Diode detectors in systems for which the signal amplitude is not that important two examples. Prototype . tested. in 2005. Modified. monitor . installed. in 2006. For the non-destructive measurement of the circulating beam . emittance. , ionisation profile monitors (IPM) are widely used in low energy accelerators. In such devices an electrostatic field accelerates the ionisation products from the beam-residual gas interaction towards a micro-channel plate (MCP). Either the electrons or the ions can be used for beam profile detection and when these particles reach the MCP, secondary electrons are produced, amplified and accelerated on to a readout device..
