Abstract: FIELD: photoelectron multiplier tubes for spectrometric and radiation-monitoring instruments. SUBSTANCE: method involves preliminary processing of emitters out of multiplier tube by antimony, mounting emitters in cesium vapors, evacuating cesium recess and generating photo cathode. Emitters are made from aluminum-magnum alloy. Preliminary activation of emitters, which are mounted in separate bulb, includes their heating under temperature 380± 20 C for 1.5-2 hours under pressure less than 1 101•10 -4  Pa, their cooling and subsequent heating under said pressure in cesium vapors under temperature 240±10 C for 15 minutes. Then bulb with emitters is heated up to 420+20 C. Then emitters are oxidized by oxygen under pressure 13 Pa in two steps, which duration is 15 minutes for each step and which are separated by 15 minutes. Then bulb is cooled down to room temperature, emitters are evacuated from bulb and first seven-eight emitters are covered by antimony layer under pressure which is not greater than 7•10 -3  Pa. When all emitters are mounted in photoelectron multiplier tube, said tube is heated under temperature, which is not greater than 250 C and pressure (1.3-2.6) 10(1,3-2,6)•10 -4  Pa during 2-2.5 hours. Final activation of emitters is performed in cesium vapors under same temperature until leakage current exceeds 1 mA. EFFECT: increased functional capabilities.

Title: Method for power supply of electrorocket plasma engines
Inventor: GALAJKO VLADIMIR N
IPC: H05H1/54
Filed: 1992-02-10
Granted: 1994-02-28
Abstract: FIELD: engines. SUBSTANCE: when plasma is in an irregular mode of high-conductivity a step current of engine burning is formed. The first current step is generated by adding the current of a voltage converter shifted into a mode of a current limiter, and a discharge current of capacitive power accumulator which is preliminary charged by the same converter with the charge current limitation. If the increase of plasma conductivity after the capacitive accumulator is discharged continues, then the current limiter mode of the voltage converter is also maintained and this corresponds to the second current stage. The value and durability of the current action is set as a function of plasma conductivity. When the normal conductivity of the plasma is restored the voltage converter is shifted to the voltage source mode and a nominal current is set which corresponds to the third stage. The method provides nonstop working mode of the plant, reduces the number of on-off cycles and the working medium consumption, and excludes voltage converter overload. EFFECT: improved reliability and service life.
