Abstract

Summary form only given. The cathode life test facility (CLTE) has performed real-time life testing of various thermionic cathode types since 1980. The facility originated at Rome Laboratories, Griffiss AFB. In 1992, it was moved to it present location at NSWC Crane, Crane Indiana. Since its inception, the facility has accumulated approximated 4 million total life test hours on cathodes of at least eighteen different types. Historically, the most popular cathodes under test have include reservoir cathodes, designated MK (Siemens), RV and V (CPI), and impregnated cathodes, Designated M (Semicon and Hughes), TM (CPI) and MMM (CPI). In addition, smaller numbers of more exotic cathode types have also been tested. Most cathodes are life tested at loadings of 1, 2, and 4 A/cm/sup 2/ in continuous emission mode. However, a number of cathode (e.g. cathode with 10 A/cm/sup 2/) have been tested with applied filament power only, due to limitation on the test stations available. A summary of the cathodes tested over the entire life of facility is given and the result obtained is compared. Test vehicle configuration and methods of data collection and analysis are reviewed. Emphasis is placed on comparing different cathodes by type and loading. The usefulness of data is discussed.

只提供摘要形式。自1980年以来，阴极寿命测试设备(CLTE)进行了各种热离子阴极的实时寿命测试。该设备起源于格里菲斯空军基地的罗马实验室。1992年，它被转移到它现在的位置在NSWC克雷恩，克雷恩印第安纳州。自成立以来，该设施已累计对至少18种不同类型的阴极进行了大约400万小时的寿命测试。从历史上看，最流行的阴极测试包括储层阴极，指定为MK (Siemens)， RV和V (CPI)，浸渍阴极，指定为M (Semicon和Hughes)， TM (CPI)和MMM (CPI)。此外，还测试了少量更奇特的阴极类型。在连续发射模式下，大多数阴极在1、2和4 A/cm/sup 2/的负载下进行寿命测试。然而，由于可用的试验站的限制，许多阴极(例如10 a /cm/sup 2/的阴极)仅用应用的灯丝功率进行了测试。总结了在设备的整个使用寿命中所测试的阴极，并对所得到的结果进行了比较。回顾了试验车辆的配置和数据收集和分析方法。重点放在比较不同类型和负载的阴极。讨论了数据的有用性。
