"In my experiments," Arata wrote, "the vessel with sample is baked and vacuumed. After that, 100 percent pure D2 gas is injected into the vessel. There is no 4He in the injected gas. If not, there would be no point to perform these experiments."
Takahashi provided additional information.
"Arata used a Pd tube regulating D2 gas flow from the 100 atm D2 source to remove any He-4 in the source D2 gas and to control the flow rate," Takahashi wrote. "They believed there remained 'no' He-4 in the D2 flow after filtering through the Pd tube which was set before the cell inlet. For the blank run with H2 gas, no He-4 particles were detected."
Arata confirmed Takahashi's statement and said that, for the blank runs, D2 with no sample, and H2 with sample, no 4He was found.
New Energy Times asked Arata whether he was able to detect the 4He concurrent with the heat generation.
"No," Arata wrote. "Due to the nature of the quadrupole mass spectrometers, it is impossible to detect the 4He evolution in the experiment concurrent with the heat generation. The 4He can only be detected after the finish of experiment."
In the hydrogen experiment, virtually no signal for either helium-4 or deuterium is visible. In the deuterium experiment, a distinct presence of helium-4 is observed with the quadrupole mass spectrometers.
Arata confirmed Takahashi's statement and said that, for the blank runs, D2 with no sample, and H2 with sample, no 4He was found. 試料無し+D2ガス、試料有り+H2ガス では He は検知されずとのこと。
New Energy Times asked Arata whether he was able to detect the 4He concurrent with the heat generation. 発熱の最中のHe発生を同時に測定することは可能かどうかを尋ねたところ、
"No," Arata wrote. "Due to the nature of the quadrupole mass spectrometers, it is impossible to detect the 4He evolution in the experiment concurrent with the heat generation. The 4He can only be detected after the finish of experiment." QMAS測定の性質上それは不可能とのこと、あくまでもHeの検出は発熱実験の後で行うしかないと。
