Paper Abstract

Thomson parabolic spectrograph (TPS) is a well known device, which is broadly used by researches of energy spectrums of ionic components of plasma [1]. In the recent years this device induces a new interest of researchers in connection, that for iones registration a micro-channel plate (MCP) [2-4] is used now in this particular device. That measure increased up to several ranges sensibility of registration in comparison with traditional photo film and, besides this fact, it permitted to strobe TPS and research temporary evolution ofionic spectrum ofimpulse sources. Ion research in strongly accurate electron beams at the expense of TPS has been conducted in Sukhumi physical-technical institute [5]. Here as register was used one exposure camera "UNICADR-R" with MCP, size: 70 x 90 mm2 [6]; this camera has been worked out in YNIIOFI for registration of Roentgen spectrums. The camera had a gain 1O. In this particular work are reported results of TPS researches, worked out in VNIIOFI [7]. A special track of this device is the fact, that it possesses a deviating system of registrating on basis of constantly operating magnets and regular registration system on basis of amplifying section image converter tube (ICT) a PIM-104 [8]; its chevron MCP permits to receive a gain 106. Tuning and calibration of device has been conducted at the expense of plasma accelerator accessed with erosion electrode. Scheme of disposal for TPS research is shown on figure 1.
