“…We successfully developed micro channel plate photomultiplier tubes (MCP-PMTs) [8][9][10][11], R10754-07-M16 (N), with Hamamatsu Photonics K.K. The MCP-PMT has dimensions of 27.6 Â 27.6 Â 13.1 mm 3 , an effective area of 22 Â 22 mm 2 , and 4 Â 4 anode pads, each having a size of 5.6 Â 5.6 mm 2 .…”

“…The impact damages the photocathode and shortens its usable life. One approach to limit this damage is to apply a thin window film on the top surface of the MCP closest to the photocathode [ Kishimoto et al ., ]. The film must be thick enough to serve as a barrier to the ions, yet thin enough to allow input electrons with energies of ~100–200 eV from the photocathode to enter the pores.…”

Microchannel plate fabrication using glass capillary arrays with Atomic Layer Deposition films for resistance and gain

Microchannel plates (MCPs) have been used for many years in space flight instrumentation as fast, lightweight electron multipliers. A new MCP fabrication method combines a glass substrate composed of hollow glass capillary arrays with thin film coatings to provide the resistive and secondary electron emissive properties. Using this technique, the gain, resistance, and glass properties may be chosen independently. Large‐area MCPs are available at moderate cost. Secondary emission films of Al2O3 and MgO provide sustained high gain as charge is extracted from the MCP. Long lifetimes are possible, and a total extracted charge of 7 C/cm2 has been demonstrated. Background rates are low because the glass substrate has little radioactive potassium 40. Curved MCPs are easily fabricated with this technique to suit instrument symmetries, simplifying secondary electron steering and smoothing azimuthal efficiency.

“…The route followed by the Belle-II Collaboration involved the use of a thin (5-10 nm) aluminium oxide film acting as an ion barrier [70] in MCP-PMTs with Chevron configuration. The film may be placed between the photocathode and the first MCP, with however a strong reduction of the photoelectron collection efficiency from 60 to 35%.…”

a b s t r a c tA micro-channel plate is an array of miniature electron multipliers that are each acting as a continuous dynode chain. The compact channel structure results in high spatial and time resolutions and robustness to magnetic fields. Micro-channel plates have been originally developed for night vision applications and integrated as an amplification element in image intensifiers. These devices show single-photon sensitivity with very low noise and have been used as such for scintillating fiber tracker readout in high-energy physics experiments. Given their very short transit time spread, micro-channel plate photomultiplier tubes are also being used in time-of-flight and particle identification detectors. The present paper will cover the history of the micro-channel plate development, basic features, and some of their applications. Emphasis will be put on various new manufacturing processes that have been developed over the last few years, and that result in a significant improvement in terms of efficiency, noise, and lifetime performance.
