Microchannel Plate Detectors
A microchannel plate (MCP) is an array of 104-107 miniature electron multipliers oriented parallel to one another (fig. 1); typical channel diameters are in the range 10-100 μm and have length to diameter ratios (α) between 40 and 100. Channel axes are typically normal to, or biased at a small angle (~8°) to the MCP input surface. The channel matrix is usually fabricated from a lead glass, trea...
متن کاملLow Intensity Beam Diagnostics with Microchannel Plate Detectors
A non destructive low intensity ion beam profile monitor has been designed and tested. The system is based on a MCP that detects the residual gas ionization produced by the ion beam. The detector is coupled to a phosphorous screen for the readout of the vertical and horizontal density profiles. Experimental results have shown that the system is able to detect beam intensities as low as 10 pps w...
متن کاملCross Strip Anode Imaging Readouts for Microchannel Plate Detectors
We have developed a novel microchannel plate readout scheme, the cross strip anode. The cross strip anode has a coarse (0.5mm) multilayer metal and ceramic cross strip pattern that encodes event positions by direct sensing of the charge on each strip and subsequent determination of the charge cloud centroid for each event. Event position encoding is accomplished with chip level preamplifiers on...
متن کاملDetermining time resolution of microchannel plate detectors for electron time-of-flight spectrometers.
The temporal resolution of a 40 mm diameter chevron microchannel plate (MCP) detector followed by a constant fraction discriminator and a time-to-digital converter was determined by using the third order harmonic of 25 fs Ti:sapphire laser pulses. The resolution was found to deteriorate from 200 to 300 ps as the total voltage applied on the two MCPs increased from 1600 to 2000 V. This was likel...
متن کاملMicrochannel plate cross-strip detectors with high spatial and temporal resolution.
The cross-strip imaging readout employs charge division, and centroiding, of microchannel plate charge signals detected on two orthogonal layers of sense strips to encode event X-Y positions and times. We have developed cross-strip detectors and fully parallel channel position encoding electronics. The front-end amplifiers utilize two 32-channel pre-amplifier ASICs that send signals to a full 6...
