| Cn cellenee cn. £leEtroni 10WP7 The type 10WP — is o 10-inch electrostatic focus and magnetic deflection cathode -ray tube suit - able for rador applications. A low-voltage electrostatic focus lens is employed, designed to operate at of near cathode potential to afford substantially automatic focus, independent of accelerator volt - age variations. In addition, the 1OWP — employs a high resolution electron gun, MECHANICAL DATA BASE: Small Shell Duodecal 6+ Pin 6) CAP: Recessed Small Cavity 2 TERMINAL CONNECTIONS: Pin | Heater Pin 11 Cathode Pin 2 Grid #1 Pin 12 Heater Pin 6 Grid #4 Cap” Grids #3 ond #5 i Pin 10Grid #2 (Collector ) © =—— / ELECTRICAL DATA KLS%H GENERAL CHARACTERISTICS : Oe) 10WP7 10WP14 10WP19 Phosphor 7 #14 #19 Fluorescence Blue Blue Orange BOTTOM VIEW Phos phorescence Yellow Orange Orange Persistence Long Medium-long Long Focusing Method Electrostatic Electrostatic Electrostatic Deflecting Method Magnetic Magnetic Magnetic Deflection Angle 50 50° 500 HEATER CHARACTERISTICS: Heater Voltage 6.3 volts Heater Current 0.610% amps.

  • At or near this rating, the effective resistance of the collector supply should be adequate to limit the collector input power to 6 watts, The screen of the 10WP19 can be permanently damaged should the current density be permitted th rise too high, To prevent buming, minimum beam current densities should be employed. A Collector, Grids $3 and 45 are connected internally and referred to as Collector, Brilliance and definition decrease with decreasing collector voltages. In general, collector voltage should not be less than 7,000 volts. # Cathode should be returned to one side or to the mid- tap of the heater transformer winding. © With grid #1 voltage adjusted to produce a collector current of 100 iA, with the pattern adjusted for best overall focus, Measured with a 525-line interlaced and synchronized 6X 8 inch pattern, with interlaced line blanking (current measured before applying blanking ). © Visual extinction of focused 6X 8 inch raster pattern. @ Measured with a 525-line interlaced and synchronized pattern with interlaced line blanking. Pattern width adjusted to 90% of minimum useful screen diameter, Ib- 100 YA., measured before applying blanking. Line width is the merged raster height divided by the number of lines (262.5 ) (measured in center of tube face). To avoid damage to the screen of the 10WP19, it is recommended that the screen current be not more than 50 JA. when measuring line width, The line width under this condition will be 0,016 inch maximum (current measured before applying blanking }. Oi The center of the undeflected, focused spot will fall within a circle of 1/2-inch radius concentric with the center of the tube face, with tube shielded.
