One of the original investigators, Dr. K. Masuda, transferred to Nagoya University. This research was made by E. Shibamura and Prof. N. Hasebe. Prof. Hasebe also transferred from Ehime University to Waseda University on September 1998. Also, the office of Shibamura moved from Urawa-city to Koshigaya-city at the end of March 1999. After the middle of 1998 the major experiment was made at Waseda University.A parallel plate type gridded ionization chamber was made in thick enclosure made of stainless steel. A low-noise charge-sensitive preamplifier was made and tested. The noise was about 350 electrons at no load and less than 500 electrons at load of 40 pF, which was satisfactory.By the end of fiscal year 1998, vacuum system including gas-filling system was prepared and ionization signal was observed for ionizing radiation. The electron drift velocity was observed in pure Xe gas.After 1999, electron drift velocity and diffusion constant of electrons in High pressure Xe gas was measured. Some of the results in electron drift velocity will be published in Jpn. J. Appl. Phys. Vol. 42 (2003) 333-334 with the title "Measurement of Electron Drift Velocities in the Mixture of Xe and He for a High-Pressure Xe Gamma-Ray Detector".

最初的研究者之一K博士增田，转学到名古屋大学。这项研究是由E。Shibamura和N.长谷部1998年9月，长谷部教授也从爱媛大学转到早稻田大学。此外，1999年3月底，Shibamura的办公室从浦和市搬到了越谷市。1998年年中以后，在早稻田大学进行了主要实验，在不锈钢厚外壳内制作了一个平行板式栅网电离室。研制了一种低噪声电荷敏感三极管。噪声在无负载时约为350个电子，在负载为40 pF时小于500个电子，这是令人满意的。到1998财政年度末，准备了包括充气系统在内的真空系统，并观察到电离辐射的电离信号。1999年以后，又测量了电子在高压氦气中的漂移速度和扩散常数。电子漂移速度的部分结果将发表在Jpn上。J.Appl.Phys.Vol.42（2003）333-334，标题为“Measurement of Electron Drift Velocities in the Mixture of H2O and He for a High-Pressure H2O Gamma-Ray Detector”。
