| Owner/Operator | Diamond, Harwell Chilton Science Campus, South Oxfordshire, UK |
| Status | Operational |
| Status Details | I04-1 is the engine for the XChem fragment drug discovery engine. |
| %Time Available (general use) | 100 |
| Experiments | SAD, MONOCHROMATIC |
| Experiments Details | I04-1 uses medium throughput data collection for rapid structure solution using the pan-dataset approach (PanDDAS) - up to 600 measurements per day. https://www.jove.com/t/62414/achieving-efficient-fragment-screening-at-xchem-facility-at-diamond |
| Special Capabilities | Automatic Crystal Alignment, High Throughput |
| Special Capabilities Details | Single anomalous diffraction (SAD) experiments benefit from energy set near the Bromine edge - most usual elements will give very good anomalous signal for at least great anomalous fourier maps. |
| Services | High quality data collection, High speed data collection, Mail-in, Processing, Structure solution |
