Applications

Overview

The Photek family of Multi-Anode PhotoMultipler Tubes (MAPMT) utilise Microchannel Plate (MCP) electron multipliers to provide the world’s fastest MAPMTs, with individual pulse risetimes to 175 ps and Transit Time Spread (TTS) to 30 ps rms.

 

There are multiple configurations to choose from, depending on requirements:

 

MAPMT253

A 59 mm tileable square format, with a 53 x 53 mm active area, with standard configurations of 64, 256, and 1024 anodes.

 

MAPMT226

A ruggedised 80 mm package with a 26.5 x 26.5 mm active area having 256 anodes.

 

Both variants can be customised with unique anode patterns and connectors.

Specifications

Photocathodes Response

Available photocathodes on fused Silica window.

Optical fibre optic window will reduce sensitivity and no response below 300nm

Average Single Photon Pulse

Average of 50 single photon pulses
measured on 5 GHz, 20 GS/s LeCroy oscilloscope,
using sin(x)/x interpolation and illuminated using a
Photek LPG-405 pulsed laser.
