直流電漿產生器一直是研究基本電漿性能便宜且方便的良好實驗對象。 本論文設計了一種直流電將設備系統。 選擇氬氣作為電漿源，並使用油壓式真空幫浦輔助擴散式泵浦來達到高真空。 在產生電漿時，直流放電被用來從金屬絲表面引發熱電子發射，然後引起電子雪崩。 為了增加電漿密度，使用了上千個永久磁鐵來形成多極磁場，該多極磁場可防止電子和離子直接與真空室的壁（不銹鋼）碰撞。 通過自製的電路放大器和Langmuir探針測量電漿密度和電子溫度。 信號發生器會激發離子聲波，為測量Landau阻尼和等離子波回波做準備。

DC plasma generators have always been inexpensive, but convenient experimental apparatus to investigate basic plasma properties. This thesis designs a system of a DC plasma device. The plasma source was selected as argon gas, and an oil rotary vacuum pump assisted by a diffusion pump is used to achieve a high vacuum. In generating plasmas, the DC discharge is employed to induce thermionic emission from the metal filament’s surface which then causes the avalanche of electrons. In order to increase plasma density, a thousand permanent magnets are employed to form a multi-pole magnetic field, which prevents electrons and ions getting lost to the wall (stainless steel) of the vacuum chamber directly. The plasma density and electron temperature are measured by a self-made circuit amplifier and a Langmuir probe. Ion-acoustic waves are excited by the signal generator to prepare for the experimental studies of ion acoustic wave (IAW) Landau damping and plasma waves echo.
