REPAIR & MAINTENANCE ACTIVITIES

共焦更换扫描卡、电流计电机、计算机 硬盘和主板 双光子：更换扫描卡。 透镜的翻新。 更换压电镜支架 （禁止使用该系统约2个月。）离子束 溅射镀膜机：定期重建离子束枪。 固定 电源。 铂镀膜机：离子枪重建。 Denton 蒸发器：秋天，完全重建扩散泵和清洁 整个系统 春末，蒸发器退役。 Edwards蒸发器/涂布机：经过测试和调试， 丹顿的地方。 冷冻断裂装置：经过测试， 目前已投入使用，并定期使用。 该系统 存放了好几年 正因为如此， 真空和低温泵的固定花费了很多时间。 努力 该单位现在是完全功能的铂/碳阴影或 FESEM双涂层。 HPF：高压气缸 暴露了 该单位被送往列支敦士登进行整修。 单位还没有回来。 我们希望能在一年内恢复 月 4D系统：在系统中添加了第二个硬盘。 SEM： 追踪了真空泵的泄漏情况。 此外，低信号电平是 信号周期性不稳定（超过 全年的一半时间。 终于稳定下来了 在过去的两个月里 隔膜泵在常规基础上进行改造， 基础 当前（Gatan）数字化系统的问题 耗费了很多员工的时间。 因此，该系统将被替换 今年晚些时候，4PI将推出一个新的数字化系统。

Confocal Replacement of a scan card, galvonometer motor, computer hard drive, and board. Two-Photon: Replacement of a scan card. Refurbishing of a lens. Replacement of a piezo electric mirror mount (prohibited use of the system for approximately 2 months.) Ion beam sputter coater: Rebuilt the ion beam gun on a regular basis. Fixed the power supply. Platinum coater: Ion gun was rebuilt. Denton evaporator: Fall, completely rebuilt the diffusion pump and cleaned the entire system. Late spring, evaporator was decommissioned. Edwards evaporator/coater: Was tested and commissioned and did take the place of the Denton. Freeze Fracture Unit: Was tested and commissioned and is now being used on a regular basis. The system had been in storage for several years. Because of this, the testing of the vacuum and the fixing of the cryo-pump took much time. effort. The unit is now fully functional in platinum/carbon shadowing or double coating for FESEM. HPF: High pressure cylinder was compromised. The unit was sent to Liechtenstein to be refurbished. The unit is still not back. We are hoping to get it back within one month. 4D System: A second hard drive was added the system. SEM: Traced the leakage of ultrahigh vacuum. Also, low signal level is being worked on. Signal has been unstable periodically (more than half the time) throughout the year. It has finally become stable within the last two months. Diaphragm pump was rebuilt on a regular basis. Problems with the current (Gatan) digitization system have consumed much staff time. As a result, the system will be replaced with a new digitization system from 4PI later this year.
