Vintage Geiger-Muller counter MSTR-4 radiation detector tube NOS

Description: X-ray counter MSTR-4 Also, this product can be called: MSTR 4, MSTR4, MSTRch, mstr-4, mstr 4, mstr4, mctp-4. Photo made with Tesla coil - its have unique teal color of glow, so you can use it as detector tube or as spectral glowing tube. MSTR-4 self-extinguishing X-ray counter, with a copper cathode, a glass balloon and a mica end window. Symbol: MSTR-4 counter, where: M - copper cathode. C - self-extinguishing counter. T - end window. R - for x-ray structural or x-ray spectral studies. 4 - indicates the region of the spectrum for which this counter is intended. Also on the site zapadpribor.com similar X-ray counters are presented. Specifications MSTR-4: The counting start voltage is 1200 V. Operating voltage - 1350 V. The smallest length of the plateau is 200 V. Load resistance - from 8 MΩ to 15 MΩ. The largest parasitic capacitance allowed in the input circuit of the counting and measuring device is 25 pF. The active resistance of the input of the counting device is 1 MΩ. The greatest slope of the MSTR-4 plateau is 0.05%/V. The highest counting rate is 25,000 pulses/min. The surface density of the entrance window mica is 5.9 mg/cm2. The registration range is from 0.3 keV to 3 keV. Dosimetric characteristics: - Nmax=3 104; - Nf=65. Ambient temperature - +5° С to +35° С. Dimensions: - length - 180 mm; - width - 40 mm. Weight - no more than 50 g. MSTR-4 X-ray counters (Geiger counters) are capacitors in which the space between the electrodes is filled with gas. At high field strengths, a self-sustained discharge occurs in the capacitor if a charged particle enters the detector volume. The meter balloon is a glass tube with a layer of copper deposited on the inner surface, which serves as a cathode.
