Movie of SPEED Mk.II for oscillation of press and detectors
movingMkII-2.m4vAbstract:
The BL04B1, “High Pressure and High Temperature” is a white X-ray beamline from a bending magnet. The use of high energy (20 - 150 keV) is suitable for energy-dispersive diffraction experiment using a solid state detector (SSD) and X-ray radiography experiment using a CCD camera. Moreover, the double silicon crystal monochromator can select the X-ray energy between 30 and 60 keV from synchrotron X-ray radiation through bending magnet, the 2D-XRD data is acquirable using large area CCD camera. This beamline is designed to conduct research on the structure and properties of materials in the Earth's interior under high-pressure and high-temperature conditions. High-pressure and high-temperature experiments are performed using two large-volume presses: SPEED-1500 and SPEED-Mk.II-D, both of which are installed in the tandem experimental stations (Experimental hutch 1, hutch 2) . These large-volume presses are constructed by double-stage (Kawai-type) high-pressure vessels with two kinds of the anvils; the tungsten carbide (WC) and the sintered diamond (SD). The pressure can be reached up to 65 GPa with using WC anvil and over 120 GPa with using SD anvil, and its high pressure condition, and its high pressure and high temperature condition is corresponding to the upper or the lower mantle region in Earth's interior.
ビームラインの概要：
BL04B1（高温高圧）は偏向電磁石による白色X線が利用可能なビームラインで、高エネルギーX線（20～150 keV）を使って半導体検出器（SSD）によるエネルギー分散型X線回折測定と、CCDカメラによるX線ラジオグラフィー測定を行うことができます。また、X線分光装置を使用して30～60 keVの単色X線も利用でき、大面積CCDカメラによる2次元X線回折イメージの取得も可能です。本ビームラインは、高温高圧状態にある地球内部物質の構造や物性を調べることを目的に設計され、実験ハッチ1、2にそれぞれタンデムに設置された2つの大容量高圧プレス装置（SPEED-1500、SPEED-Mk.II-D）を使って高温高圧状態の実験を行うことができます。2つの大容量高圧プレス装置は2段押しタイプ（川井型）で、タングステン・カーバイド（WC）、および焼結ダイヤモンド（SD）の2種類のアンビルに対応しています。タングステン・カーバイドアンビル（26 × 26 × 26 mm3）を用いた場合に65 GPa、焼結ダイヤモンドアンビル（14 × 14 × 14 mm3）用いた場合に最大120 GPaまでの高圧力を3000 Kの高温下で発生させることが可能で、この圧力温度は地球深部の上部マントルから下部マントル領域に相当します。
