1P28 PHOTOMULTIPLYER TUBE WITH HIGH LIGHT INTENSITY DYNODE CHAIN CIRCUIT IN BRASS HOUSING I TESTED IT AND IT WORKS OK THIS DYNODE BASE CIRCUIT IS TO MAINTAIN LINEAR RESPONSE AT HIGHER LIGHT INTENSITIES. (SEE SCHEMATIC PHOTO) THIS WILL OUTPUT UP TO 8 mA INTO 50 OHMS LINEARLY. (SEE LINEARITY PLOT PICTURE) BNC OUTPUT LINEAR UP TO 400 mv INTO 50 OHMS BNC HIGH VOLTAGE INPUT MINUS 900 VDC MAXIMUM = -900 VDC AS THE NUMBER OF PHOTOELECTRONS INCREASES AT EACH STAGE, AN INCREASE IN ACCELERATION VOLTAGE IS NECESSARY TO AVOID THE PMT GOING INTO NONLINEAR RESPONSE WITH HIGHER INTENSITY ILLUMINATIONS. THE ALL METAL HOUSING IS EXCILLENT FOR RF NOISE SHIELDING. SEE ATTACHED SCHEMATIC FOR DYNODE CIRCUIT CONFIGURATION. MINUS 1250 VDC MAX HIGH VOLTAGE SUPPLY. 7 X 2.25 X 2.25 INCH HOUSING WITH 1.25 X 0.5 INCH PMT APERTURE. THE BASE HAS THREE 1/4-20 THREAD HOLES FOR MOUNTING DYNODE VOLTAGES VDC WITH -900 VDC SUPPLY C TO D1 = 64 D1 TO D2 = 143 D2 TO D3 = 190 D3 TO D4 = 221 D4 TO D7,8,9 = 279 D7,8,9,A TO GND = 50 Payment is due within 5 days of close of auction or date of purchase.
