Radiation Detectors, Bases & Stands.

Geiger-Mueller Detectors

GP 25 - NOTE: Substitute GP35 after January 2012

A complete detector assembly utilizing a 25 mm diameter end-windowed GM tube for Alpha, Beta, Gamma detection. The plastic stand includes a sample tray and features 10-slots with 1 cm spacing for performing inverse square law experiments and holding radiation absorbers.

The GM probe is easily removed from the stand for safe storage, hand-held applications or replacement.

ORDER: GP25

Component Parts.

  • GM25 GM Probe, 25mm end window with BNC connector.
  • GMS25 10 position stand with sample tray (P/N GMT01).
  • BNC3 BNC/BNC cable, 3-ft.


GMT01 Sample Tray

GM 25 - NOTE: Substitute
GM35 after January 2012

Replacement GM tube. 25 mm end window, 2 mg/cm2, Typical 100-150v plateau, 150 microsecond deadtime, BNC connector.
25 mm OD, x 90 mm L.

ORDER: GM25

GP 35

Similar to the GP 25 but with a 35 mm Geiger tube for added sensitivity and improved counting efficiency.

ORDER: GP35

Component Parts.

  • GM35 GM Probe, 35mm end window with BNC connector.
  • GMS35 10 position stand with sample tray (P/N GMT01).
  • BNC3 BNC/BNC cable, 3-ft.

GM 35

Replacement GM tube. 35mm end window, 2 mg/cm2, Typical 100-150v plateau, 200 microsecond deadtime, BNC connector. 35 mm OD, x 223 mm L.

ORDER: GM35

Splitter Box

SB100

The SB100 Splitter Box enables the use of a single connector NaI detector with the UCS30 Universal Computer Spectrometer. Two MHV connectors accept the NaI detector Input and the High Voltage Input, respectively. The BNC Signal Out connector goes to the Input connector on the back of the UCS30.

ORDER: SB100

 

 

Signal Combiner Box

SC100

The SC100 Signal Combiner Box enables the use of a dual cable NaI detector with the ST160, ST360 and ST370 line of computer-controlled counters. Connectors include an MHV Detector High Voltage Input, BNC Signal Detector Input (both from the NaI detector) and an MHV ST360 Scintillation Input to the counter.

Scintillation Detectors

SPA 38

The SPA 38 provides a complete detector assembly for gamma spectroscopy applications. The 38x38 mm NaI(Tl) crystal includes PMT and voltage divider as an integral assembly. The probe is supplied complete with a 10-position sample stand, lead shield and cables for connecting directly to the spectrometer. Resolution is typically 7% @ 662 keV.

ORDER: SPA38

Component Parts.

  • SDA38 Scintillation detector, 38x38mm with with voltage divider.
  • GMS38 position stand with sample tray and LS038 lead shield.
  • BNC6 and MHV6 cable assemblies.
