HIGH SPEED AND HIGH TEMPERATURE DEFORMATION EXPERIMENT OF SILICATES

去年磁力加速器LW2。发射器。高温炉和速度测量系统。当开始研究硅酸盐矿物的高速高温实验时。我们发现该系统中的不足之处，需要进行如下修改。以使射弹在炉内精确地撞击到小尺寸的单晶硅酸盐上。新研制了带有强磁线圈的导弹管.以获得发射装置中弹丸的精确速度。两个压电膜之间的时间测量系统是由于双现象示波器。但是...由于预算的原因，我们无法获得用于瞬时现象的存储型示波器。因此。我们准备制作一个与微机相连的A/D转换系统，用于速度测量，电磁加速器的功率由电容器槽的电位（5 μ F）决定，在几微秒内，在50 ~ 5 kA时，其功率约为1 ~ 10 kV。因此，在卷绕系统上保持保险是严峻的。我们还改变了线圈系统周围连接器部件的保险，以便在10 kV水平下运行系统。

Last year. the magnetic accerlator. LW2. launcher. high temperature furnace. and velocity measurement system were equiped at University of Tokyo. When started to investigate the high speed and high temperature experiments of silicate minerals. we found inadequate points in this system to change as follows.1. in order to get accurate collision of projectile onto small sized single crystalline silicates in furnace. the projectile guide pipe attached with strong magnetic coil was newly made.2. to obtain the accurate velocity of projectile in launcher. the time measurement system between two piezofilms was due to 2-phenomena oscilloscope. But. we cannot get the storage type oscilloscope for instantaneous phenomenon due to budget size. Thus. we are going to make A/D transfer system connected with microcomputer for velocity measurement.The power of our electromagnetic accerlator is governed by the potential of the capacitator tank (5 uF) and it is represented by about 1 to 10 kV at 50 to 5 kA within a few microseconds. Thus, it is severe to keep the insuration at the coiling system. We also changed the insuration at the connector parts around the coiling system in order to operate the system at 10 kV level.
