29 mm (1.13") photomultiplier 9125B series data
29 mm (1.13") photomultiplier 9125B series data sheet 6 characteristics 1 description The 9125B is a 29 mm (1.13") diameter, end window photomultiplier with blue-green sensitive bialkali photocathode and 11 high gain, high stability, SbCs dynodes of linear focused design. The 9125WB and 9125QB are variants for applications requiring uv sensitivity. 2 applications wide range of applications spectroscopy x-ray & gamma-ray spectroscopy photon counting of bio- and chemi-luminescent samples 3 features • • • • high gain low operating voltage good SER good pulse height resolution 4 window characteristics 9125B borosilicate spectral range**(nm) refractive index (nd) K Th U (ppm) (ppb) (ppb) 9125WB UV glass 9125QB* fused silica 280 - 630 1.49 170 - 630 1.48 160 - 630 1.46 300 250 100 8500 30 30 <10 <10 <10 * note that the sidewall of the envelope contains graded seals of high K content ** wavelength range over which quantum efficiency exceeds 1 % of peak 5 typical spectral response curves min (1) subject to not exceeding max. rated sensitivity 7 type max 25 28 65 11 1 200 2000 850 1100 3 0.1 1150 0.2 2 100 1 5 6.4 25 100 2 7.5 20 2 ± 0.5 4.5 7.5 4 33 50 100 50 30 2000 60 2000 300 300 202 -30 (2) subject to not exceeding max rated V(k-a) 7 typical voltage gain characteristics % 30 8 20 Q W 100 300 7 10 200 100 B 10 0 10 2,000 1,000 A/ l m quantum efficiency 10,000 500 wavelength nm 700 900 6 10 divider A divider B 10 5 10 1 0.1 4 10 0.2 0.4 0.6 0.8 1.0 1.2 Vk-a (kV) 1.4 1.6 1.8 2.0 gai n • • • • unit photocathode: bialkali active diameter mm quantum efficiency at peak % luminous sensitivity µA/lm with CB filter with CR filter dynodes: 11LFSbCs anode sensitivity in divider A: nominal anode sensitivity A/lm max. rated anode sensitivity A/lm overall V for nominal A/lm V overall V for max. rated A/lm V 6 gain at nominal A/lm x 10 dark current at 20 ºC: dc at nominal A/lm nA dc at max. rated A/lm nA -1 dark count rate s afterpulse rate: % afterpulse time window µs pulsed linearity (-5% deviation): divider A mA divider B mA pulse height resolution: single electron peak to valley ratio 137 Cs with 1” x 1” Nal(T1) rate effect ( Ia for ∆g/g=1%): µA magnetic field sensitivity: the field for which the output decreases by 50 % -4 most sensitive direction T x 10 -1 temperature coefficient: % ºC timing: single electron rise time ns single electron (fwhm) ns single electron jitter (fwhm) ns transit time ns weight: g maximum ratings: anode current µA cathode current nA 6 gain x 10 sensitivity A/lm temperature °C (1) V (k-a) V V (k-d1) V (2) V (d-d) V ambient pressure (absolute) kPa 8 voltage divider distribution k d1 d2 d8 11 ordering information d9 d10 d11 a A 2R R R R B 2R R R 2R 3R 4R 3R R R R 9125B series data sheet page 2 Standard High Pulsed Linearity Characteristics contained in this data sheet refer to divider A unless stated otherwise. 9 external dimensions mm The drawings below show the 9125B in hardpin format, the 9125FLB in flying lead format with temporary B14B base fitted and the 9125FLB in flying lead format. The 9125B meets the specification given in this data sheet. You may order variants by adding a suffix to the type number. You may also order options by adding a suffix to the type number. You may order product with specification options by discussing your requirements with us. If your selection option is for a one-off order, then the product will be referred to as 9125A. For a repeat order, ET Enterprises Limited will give the product a two digit suffix after the letter B, for example B21. This identifies your specific requirement. 9125 window variants W Q UV glass fused silica base variant FL flying lead base with 28.2 max temporary B14B hardpin base options S electromagnetic shielding see drawing below supplied with spectral response calibration M 112 ±3 specification options B A as given in data sheet single order to selected specification repeat order to selected specification Bnn 9.5 max 63 max 70 ±2 12.7 max 0.75 diameter flexible leads, arranged on a 19 mm pcd. temporary B14B base 29 max with electrostatic shielding 29.3 max with electromagnetic shielding conductive coating mumetal* shield (for S option) 10 base configuration (viewed from below) d11 d9 a 7 6 8 9 10 B14B 3 d3 2 d11 d8 5 d7 4 d5 d10 1 ic d6 11 12 14 13 d1 d4 d2 k B14B hardpin base (For 9125B) ‘ic’ indicates an internal connection d9 a 6 7 d3 8 5 9 d8 10 d7 4 d5 3 d10 ic 1 16 15 cl cl d6 11 FL 2 insulating sleeve 12 14 13 d1 *mumetal is a registered trademark of Magnetic Shield Corporation d4 d2 12 voltage dividers k The standard voltage dividers available for all variants of this pmt are tabulated below: flying lead base (For 9125FLB) after removal of temporary base. ‘cl’ indicates cut lead k Our range of B14B sockets is available to suit the B14B hardpin base.
