2. 太赫兹探测系统
太赫兹探测系统三频率范围内优化，包括为THz总体范围。该系统采用一个更/ NbN超导热电子测辐射热计（出演）安装在一个硅/锗透镜和低噪声低温冷却高电子迁移率晶体管（HEMT）放大器。scontel可提供最快的太赫兹接收机，具有灵敏度与最佳检测系统。
Scontel提供了两种类型的冷却系统（操作需要低温超导探测器）：
1) Liquid Helium Cryostat.
This allows for using THz detectors without expensive cryogen-free equipment. The storage dewar filled with 1 or 2 liters of helium allows for over 5 or 7 hours correspondingly of uninterrupted operation of the system. Operating temperature of the system is 4.2 K
2) Cryogen-free system.
The Closed-Cycle Refrigerator is a cryogen-free cooling system which does not use liquid helium (the operating temperature is below 2.5 K). This type of detection system would be ideal for those who want to avoid handling with liquid helium. A particular advantage is that closed-cycle refrigerators can operate continuously for months from just an electrical power source.
