COUNTER The MCP should be kept in vacuum or dry nitrogen gas atmosphere during long periods of storage. SAMPLE LONG SCALE MCP ASSEMBLY + PHOSPHOR SCREEN When outgassing from the MCP occurs, baking the MCP at 350 C maximum in a vacuum system is recommended. In addition electron bombarding may be effective. + LINEAR IMAGE SENSOR TMCPC0038EA REFERENCE 1) Japan Academic Promotion Society, 141th Committee on Micro Beam Analysis: “Micro beam analysis” Asakura Shoten, 293 (1985) HAMAMATSU PHOTONICS K.K., Electoron Tube Center 314-5, Shimokanzo, Toyooka-village, Iwata-gun, Shizuoka-ken, 438-0193, Japan, Telephone: (81)539/62-5248, Fax: (81)539/62-2205 U.S.A.: Hamamatsu Corporation: 360 Foothill Road, Bridgewater.
