摘要： PROBLEM TO BE SOLVED: To dispense with the optical axis adjustment complicated and taking time, and operate a streak camera for diagnosing optical signals safely separating away from a radiation control area. SOLUTION: An optical fiber 11a with a nonreflective coat 13 applied to the tip is inserted in a vacuum duct 1 for propagating charged particles. The charged particle 2 collides with this optical fiber 11a, and Cerenkov light 12 (12a, 12b) generated at the time this collision is propagated in the optical fiber 11a. The end part without the nonreflective coat 13 applied of the optical fiber 11a is connected and held to a flange 14 with an optical fiber vacuum lead-in terminal. An optical fiber 11b is connected to the atmosphere side of the flange 14 and also connected to a streak camera 8. The Cerenkov light 12b enters the streak camera 8 through the optical fiber 11a, flange 14 and optical fiber 11b.

摘要： PURPOSE:To provide a radiation monitor device in which the whole detecting part is miniaturized and reduced in weight, an improvement in reliability of the device and high positional resolution and detecting efficiency are attained, the detecting part has no distortion of optical characteristic, and a signal is never influenced by an external noise. CONSTITUTION:A detecting part is formed of a material emitting light by radiation or light transmission paths 11a, 11b optically connected to the material; a radiation measuring sensor 10 formed by a part of the transmission paths; and a standard light source 14 provided on a part of the sensor so as to have the form never causing an optical local distortion in optical characteristic in the transmission paths. The detecting part has a sensor for converting radiation to an electric pulse, the signal converter of the electric pulse, a light receiving element receiving the light and generating a power, and a power source circuit for supplying a voltage to the sensor and the signal converter by the power, and a signal processing part has a signal converter, a counter device, and a light emitting element. The signal processing part is connected to the detecting part by the optical fiber cables of the light transmission paths.

摘要： PURPOSE:To always achieve an accurate measurement eliminating a drop in permeability of light with a higher radiation resistance by using a pure water Cerenkov light for a charged particle beam shape monitor. CONSTITUTION:A pure water Cerenkov light emitting body 8 is arranged in a course of a charged particle beam 2 and an analog signal adder 9 is connected to photomultipliers 3 at both ends thereof. The pairs of photomultipliers 3 is placed tight on a Cerenkox light takeoff window and a Cerenkov light is incident into a corresponding photomultiplier 3 through upper and lower takeoff windows to be converted an electrical signal and then, outputted after amplified. The electrical signals outputted are added up with an adder 9 and the signals are measured with a measuring resistance 5 and an oscilloscope 4 to obtain an output proportional to the number of charged particles incident into a certain position and width of a section of the beam 2. Moreover, an arm 7 for scanning is driven to repeat measurements shifting the position of the light emitting body 8 thereby enabling measurement of a relative intensity distribution in the section of the beam 2, namely, a shape of the beam 2.

摘要： PURPOSE:To simplify construction and to improve performance by using a transparent body, optical focussing body and an optical fiber having a semispherical base. CONSTITUTION:At one end of a cylinder a transparent body having a semisphere 1 of the same diameter with said end en bloc, rod lenses 2, optical fibers 3 are prepared. At the semispherical base of the transparent body 1 the rod lenses 2 having optical fibers 3 at the one ends are arranged radially at appropriate intervals centering around the top of the semisphere concentrically. Thereby, when radioactice rays make incidence into the transparent body 1, because the charged particles speed within the transparent body 1 is larger than the photospeed within the transparent body 1, Cherenkov radiation arises, the radiation angle is changed according to the charged particle speed, the fluorescence is focussed on the fixed rod linses 2 to be directly transferred to the measuring apparatus body through the optical fibers 3 as luminous signals. Consequently electromagnetic induction is not generated, measurement is stabilized as well as the structure concerned can be made light and small.
