儀器介紹
|
本設施現有幾項設備： |
- FR-E+ SuperBright X-ray generator
- Saturn 944+CCD detector + AFC11 4-axis goniostat
- R-AXIS IV++ imaging plate area detector
- VariMax-HF confocal optical system
- VariMax-HR confocal optical system
- X-stream cryo system

|
| FR-E+ SuperBright™ |
Rigaku FR-E+是大分子結晶學目前在實驗室中X-射線強度最強的來源，提供超出一些第二代彎曲的磁鐵同步加速器beam lines的強度。它的特色如下：
|
- Work on small and poor quality crystals at home
- Minimize travel to the synchrotron
- Improve your workflow by removing the bottleneck of remote data collection
- Improved filament life increases your productivity
- Phase at home—optional dual wavelength anode increases your experimental flexibility
- Proven productivity of Rigaku X-ray sources—88% of the Home Lab structures deposited in the PDB in 2006 were collected on a Rigaku X-ray source

| Saturn 944+ CCD detector |
新的Saturn944 + 是Rigaku設計和製造的第3代的x射線繞射偵測儀，在讀出速度方面提升了近4倍的讀出速度。卓越的動態範圍和高靈敏度是使用柯達的indium-tin-oxide（ITO）CCD感應器技術，結合大格式CCD一個最佳的光纖demagnification比例，因此saturn944 +CCD是需高效能和高空間分辨率的蛋白質和大分子晶體的最佳選擇。Saturn944 + X射線繞射偵測儀是一個完美的工具，高讀出速度為8兆赫提供在最短的時間收集最大程度的數據，可在最短的時間大量篩選蛋白質晶體。
Saturn 944+的高敏感性，對微弱的繞射點的彙集是特别強有力的，從而達到高數據集完整性。使用AFC11或AFC Kappa goniometers靈活的數據收集提高覆蓋面。
