In order to verify the cold fusion reaction, the pressure in the analysis tube is set to 1 × 10 ^-2 Pa or less and a large amount of helium is contained in a large amount of deuterium (D ₂ ⁺ ) gas. It is necessary to detect (He ⁺ ) gas, but in the above-mentioned type of apparatus, both helium (He ⁺ ) gas and deuterium (D ₂ ⁺ ) gas having close masses are introduced into the analysis tube c. Therefore, it is difficult to measure helium (He ⁺ ).

The present invention introduces a large amount of gas into an analysis tube to remove deuterium gas and increase the partial pressure of helium gas,
It is an object of the present invention to provide an exhaust system capable of performing mass spectrometry suitable for demonstrating cold fusion.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIG. 3. In the figure, reference numeral 1 indicates a reaction chamber at room temperature, and inside thereof, for example, platinum and palladium electrodes An experiment of cold fusion is performed by energizing hydrogen (D ₂ ⁺ ). A mass analysis tube 2 for analyzing the gas generated therein is connected to the reaction chamber 1 by a connection pipe 3 which constitutes a part of an exhaust device 4, and the inside of the mass analysis tube 2 is connected to a gas. An exhaust device 4 for exhausting to a vacuum for analysis is connected. The mass analysis tube 2 contains, for example, a secondary electron multiplier, a filament, a quadrupole electrode, etc., an ionization vacuum gauge 5 is provided outside, and a turbo molecular pump 6 and a solenoid valve are provided inside the mass analysis tube 2. 7 and a rotary pump 8 are connected in series to form an exhaust device 4, for example, 10 ⁻⁸ P
It is evacuated to a high vacuum of a or less.

In the experiment of the cold fusion reaction, the change in the amount of helium gas in the gas generated in the reaction chamber 1 is measured, and when the change can be confirmed, the cold fusion is proved. However, as described above, although the measured value of helium gas tends to be low and the change cannot be clearly measured, in the present invention, the non-evaporable getter pump 9 is interposed in the connection pipe 3. The reaction chamber 1
Most of the deuterium (D ₂ ⁺ ) in the gas inside is adsorbed and removed by the getter pump 9, and the remaining gas in which the deuterium component is reduced is guided to the mass spectrometer tube 2. Therefore, helium (H ⁺ ) The measured value rises and the change becomes clear. The getter pump 9 is a commercially available known getter pump.
It is adsorbed and exhausted at an exhaust speed of about (l / s), and the adsorbed gas diffuses into the inside of the cartridge, the surface of the cartridge can be kept in an active state, and the inactive gas is not exhausted.

The getter pump 9, the turbo molecular pump 6 and the rotary pump 8 are operated to evacuate the inside of the mass analysis tube 2 to 10 ^-8 Pa or less, and instead of analyzing the gas from the reaction chamber 1, the connection pipe As a result of flowing He gas containing 51.4% of deuterium (D ₂ ⁺ ) gas from the end of FIG. 3 as in the case of FIG. 2, the helium gas was analyzed.
The detection results shown in are obtained. According to this, the measured value of deuterium (D ₂ ⁺ ) was significantly reduced from the conventional value by 1 × 1.
0 ^-8 A becomes less negligible, helium (the He ⁺⁾ measurement of increased 8 × 10 ^-8 A more significantly, it is possible to easily detect the change in the measured value of the helium, thus Demonstrate cold fusion reliably.

[0009]

As described above, according to the present invention, since the non-getter pump is interposed in the connecting pipe for guiding the gas generated in the reaction chamber at room temperature to the mass spectrometer, the helium gas generated in the reaction chamber. Can increase the measured value of
Effects such as cold fusion can be demonstrated by clearly detecting the change in the measured value of helium gas that changes when cold fusion is performed in the reaction chamber, and its configuration is relatively simple and can be manufactured at low cost. There is.
