In order to ensure that your trip to the ESRF is successful, before using the ESRF MX beamlines please read this scientific article: The Care and Nurture Of Undulator Data Sets. It outlines the many simple things which should be done to ensure that the data collected on an undulator beamline is of as high a quality as possible.
Here are some recommended starting points for collection on MX beamlines (please talk to your local contact/supervisor for further guidance):
| Beamline | Typical exposure Time | Minimum exposure time | Number of passes | Typical transmission for MAD/SAD |
|
|---|---|---|---|---|---|
| ID14-1,2,3 | 1-5 sec | 0.3s/degree | 3 | Usually 100% |
|
| ID14-4 | 1 sec | 0.3s/degree | 3 | 20% |
|
| ID23-1 | 0.1 - 1 sec | 0.1s/degree | 1 | 1-5% |
|
| ID23-2 | 1 sec | 0.1s/degree | 1 | 1-5% |
|
| ID29 | 0.1 - 1 sec | 0.1s/degree | 1 | 1-5% |
|
Some observations on the importance of cryostream to sample distance are noted here.
