Breakdown characteristics in DC spark experiments of copper focusing on purity and hardness
/ Yokoyama, Kazue (KEK, Tsukuba) ; Fukuda, Shigeki (KEK, Tsukuba) ; Higashi, Yasuo (KEK, Tsukuba) ; Higo, Toshi (KEK, Tsukuba) ; Matsumoto, Shuji (KEK, Tsukuba) ; Santiago-Kern, Ana Rocia (CERN) ; Pasquino, Chiara (CERN) ; Calatroni, Sergio (CERN) ; Wuensch, Walter (CERN)
The breakdown characteristics related to the differences in purity and hardness were investigated for several types of copper using a DC spark test system. Three types of oxygen-free copper (OFC) materials, usual class 1 OFC 7-nine large-grain copper and 6-nine hot-isotropic-pressed (HIP) copper with/without diamond finish, were tested with the DC spark test system.

Tunability and Power Characteristics of the LEBRA Infrared FEL
/ Tanaka, Toshinari ; Hayakawa, Ken ; Hayakawa, Yasushi ; Mori, Akira ; Nogami, Kyoko ; Sato, Isamu ; Yokoyama, Kazue
Application of the infrared (IR) Free-Electron Laser (FEL) was started in October 2003 at the Laboratory for Electron Beam Research and Application (LEBRA) of Nihon University. The FEL system consisted of silver-coated copper mirrors has demonstrated wavelength tunability ranged from 940 to 6100 nm as a function of the electron energy and the undulator K-value. [...]
