| PHOTOMULTIPLIER TUBE R446 Multialkali Photocathode Sensitive to 870 nm 28 mm (1-1/8 Inch) Diameter, 9-Stage, Side-On Type The R446 features high quantum efficiency, high current amplification, good S/N ratio and wide spectral response from UV to near infrared. The R446 employs a UV-transmitting glass envelope for UV sensitivity extension. The R446 is well suited for use in broad-band spectrophotometers, atomic absorption spectrophotometers, chromatographs, NOx analyzers and other precision photometric instruments.

B: The light source is a tungsten filament lamp operated at a distribution temperature of 2856K. Supply voltage is 100 V between the cathode and all other electrodes connected together as anode. C: Red/White ratio is the quotient of the cathode current measured using a red filter (Toshiba R-68) interposed between the light source and the tube by the cathode current measured with the filter removed under the same conditions as Note B. D: The value is cathode output current when a blue filter (Corning CS 5-58 polished to 1/2 stock thickness) is interposed between the light source and the tube under the same condition as Note B. E: Measured with the same light source as Note B and with the voltage distribution ratio shown in Table 1 below.

G = Gain. f = Bandwidth of the system in hertz. 1 hertz is used. S = Anode radiant sensitivity in amperes per watt at the wavelength of peak response. I: The rise time is the time for the output pulse to rise from 10 % to 90 % of the peak amplitude when the entire photocathode is illuminated by a delta function light pulse. J: The electron transit time is the interval between the arrival of delta function light pulse at the entrance window of the tube and the time when the anode output reaches the peak amplitude. In measurement, the whole photocathode is illuminated. K: Hysteresis is temporary instability in anode current after light and voltage are applied.

TIME 0 5 6 7 (minutes) F: Measured with the same supply voltage and voltage distribution ratio as Note E after removal of light. G:Measured at a supply voltage adjusted to provide an anode sensitivity of 100 A/lm. H: ENI is an indication of the photon-limited signal-to-noise ratio. It refers to the amount of light in watts to produce a signal-to-noise ratio of unity in the output of a photomultiplier tube. li TPMSB0002EA Hysteresis = lmax. li lmin. x 100 (%) (1)Light Hysteresis The tube is operated at 750 V with an anode current of 1 A for 5 minutes. The light is then removed from the tube for a minute. The tube is then re-illuminated by the previous light level for a minute to measure the variation. ((2)Voltage Hysteresis The tube is operated at 300 V with an anode current of 0.1 A for 5 minutes. The light is then removed from the tube and the supply voltage is quickly increased to 800 V. After a minute, the supply voltage is then reduced to the previous value and the tube is re-illuminated for a minute to measure the variation.
