METAL PACKAGE PHOTOMULTIPLIER TUBE
R7400U SERIES
Compact size (16 mm diameter, 12 mm seated length), Fast Time response (rise time 0.78 ns)
The R7400U series is a subminiature photomultiplier tube with a 16 mm diameter and 12 mm seated length. A precision engineered 8-stage electron multiplier (composed of metal channel dynodes) is incorporated in the TO-8 package to produce a noise free gain of 700,000 times (R7400U). The R7400U series also features excellent response time with a rise time of 0.78 ns. Various types of the R7400U series are available with different spectral response and gain ranges, including those selected specifically for photon counting applications. Hamamatsu also provides a hemispherical lens input option to the series (R7401 and R7402), effectively doubling the active area.

FEATURES
World's smallest photomultiplier tubes assembled in a TO-8 metal package (1/7th of the Hamamatsu R647). The necessary components are built into a TO-8 package while retaining full photomultiplier tube performance to create a new generation of photosensors. Photon counting type: R7400P. The R7400P is specially selected on account of low noise and high gain for use in photon counting applications. Hemispherical lens window types: R7401 (bialkali), R7402 (multialkali). The hemispherical lens window doubles the effective input area to 12 mm in diameter.

D Type Socket Assemblies E5770/E5780
The E5770 and E5780 are compact socket assemblies incorporating a voltage divider circuit comprised of resistors and capacitors. These socket assemblies are designed to provide the output signal directly from the anode of the metal package photomultiplier tube.
Grounded Electrode Anode/Cathode Anode 2.8 M Divider Resistance (Total) Maximum Linear Output of Photomultiplier Tube (DC Mode) 13 A Output Signal Cathode Grounded Anode Grounded Pulse -- DC/Pulse DC/Pulse
Type No. E5770 E5780
* When the E5770 is used with the anode at a positive high voltage, the negative high voltage (-HV) terminal should be grounded and a positive high voltage applied to the ground terminal. In this arrangement, a high voltage differential is generated between the output and an external amplifier, so use a decoupling capacitor that can withstand a high voltage. ** In the E5780, the shield of the signal output cable is connected to the grounded cable, so the E5780 can be used only for negative high voltage operation. Consult our sales office when the E5780 is needed for positive high voltage operation. PC-board Mounting Type E5770

METAL PACKAGE PHOTOMULTIPLIER TUBE R7400U SERIES
WARNING: HIGH VOLTAGE
The metal package photomultiplier tubes are operated by applying a high voltage. Use extreme caution to avoid electrical shock and damage to the peripheral equipment and be sure to provide adequate safety measures as needed. As safety measures, an insulation cover is fitted to the metal package which is electrically connected to the photocathode. When operated with the cathode at a high voltage (anode HIGH VOLTAGE ground scheme), the metal package will be at this same high voltage level. Removing the insulation cover is extremely dangerous, so never attempt to remove it from the package.
RELATED PRODUCTS PHOTOSENSOR MODULES H6779/H6780/H5784 SERIES
The H6779/H6780 series are new light sensor modules including the compact photomultiplier tube, (METAL PACKAGE PMT) and operating power supply. It features low voltage operation (+15 V) and low power consumption (Approx. 450 mW for H6779/H6780). Compared with current light sensors, it has several advantages like high sensitivity, wide dynamic range and fast time response. These are featured by the PMT and the Cockcroft-Walton high voltage power supply. The H5773/H6779 series are on-board types which facilitates mounting directly on a printed circuit board and the H5783/H6780 series have a cable output. H5784 series are cable out type with an amplifier of DC to 20 kHz bandwidth. These versions accept direct light input or an optical fiber with the optional fiber connector of E5776.
