HIGH SPEED AND HIGH TEMPERATURE DEFORMATION EXPERIMENT OF SILICATES

去年。磁加速器。LW2。发射器。高温电炉。和速度测量系统在东京大学装备。开始研究硅酸盐矿物的高速高温实验。我们发现这个系统有以下不足之处。为了使弹丸与小尺寸单晶硅酸盐在炉内精确碰撞。本文研制了一种新型强磁导弹管。得到发射装置中弹丸的准确速度。两个压电薄膜之间的时间测量系统是由于双现象示波器。但是。由于预算规模的原因，我们无法获得瞬时现象的存储型示波器。因此。我们准备制作一套连接微机的速度测量A/D转换系统。电磁加速器的功率由电容器槽的电位（5uf）决定，在50至5ka时，在几微秒内约为1至10kv。因此，在卷绕系统中保持保险是一项严峻的问题。我们还更改了线圈系统周围连接器部分的保险，以便在10kv水平下操作系统。

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.
