mardtb 全自动准直优化系统
综述:
通过mardtb desktop beamline,即mardtb全自动准直优化系统,我们将所有用户在同步加速器光源束线工作站所体验到的功能引进到实验室仪器中,它提供了高自动化程度,几乎所有的调节都是自动化的,所有的电机都由通过ETthernet连接到主电脑的的微处理器来控制.
亮点:
多用性: | 仪器可以配置各种光源,从Mo密封靶光源,到最新的同步加速器,仪器可以配置各种探测器,比如mar345成像板探测器,SX-165/MX-225 CCD探测器,PILATUS3 200K/300K/1M或者EIGER 1M/4M像素探测器. |
自动光束校准: | 由于万向悬架技术的应用,及内置电离室和完全电机驱动化的应用,此仪器通在相应的操作界面,就可自动进行光束校准. |
反向PHI 的模式: | 内置的CHI 旋转, 可使装在PHI 角上的测角头转到90度朝下垂直的方向,可以非常方便的装卸晶体. |
内置视频: | 内置的视频摄像头将会实时监视样品位置的大约2 x 1.5 mm区域范围,并将其视频图像传入到控制用的计算机上,以使晶体对中更简单易行. |
真正的2theta角: | 带动2theta的电机,可使探测器抬高30度角度. |
高度优化的低温环境: | Mardtb为一系列低温装置提供了固定的支架(例如Oxford Cryosystems, Oxford Instruments, Rigaku Xtreme, 等等),可调节冷气流,来确保样品不结霜和除霜. |
高达22个电机: | 根据desktop beamline的配置(见下文),desktop beamline装有高达22个电机. |
可扩展功能: | desktop beamline通过用行业标准的高速的CAN-bus,可以在不需改变硬件的情况下,操控多达32个电机. |
