| 15 | == Questions to consider before the beamtime - the pre beamtime form helps discussing these questions == | ||
| 16 | |||
| 17 | Weeks before the actual beamtime the Usergroup should think about the needs for the experiment and get in contact to the DAQ / IT group at FLASH and define several boundary conditions: | ||
| 18 | |||
| 19 | * **What kind of data you want to record in the FLASH DAQ?** | ||
| 20 | ** Several options of the photon diagnostic are available which are NOT operated as standard (VLS, OPIS, ... see [[Photon Diag pages)>>url:http://photon-science.desy.de/facilities/flash/photon_diagnostics/index_eng.html||shape="rect"]] | ||
| 21 | ** What kind of ADC is the best one for you? Are amplifiers needed? what sample rate, how many channels ... | ||
| 22 | ** several types of cameras can be integrated in the FLASH DAQ system - talk to the experts (well in advance !) if you plan to use cameras. | ||
| 23 | ** For detector systems such as pnCCD imaging- detectors and ion/electron spectrometers available at the CAMP end-station please contact us to discuss your particular requirements (well in advance !) | ||
| 24 | * **Do you have own detectors to be recorded ?** | ||
| 25 | ** It has to be checked how they can be stored on the FLASH data storage (gpfs) | ||
| 26 | ** They could probably be included in the FLASH DAQ system - //this needs sufficient lead time. Talk several WEEKS before the beam time to the local contact / experts // | ||
| 27 | * **What parameters you need to monitor life during the beamtime?** | ||
| 28 | ** how you plan to monitor the parameters in jddd or Python (if absolutely needed: Matlab, Labview) ? | ||
| 29 | ** do you need online treatment of data ( averaging, integration of peaks ...) ? | ||
| 30 | ** do you have to control Hardware from FLASH ( e.g. delaylines ...). Do you need scans with online display ? - //IF the control has to be done for a NOT DESY computer ( not DESY/FLASH login) this requires special attention as well . It wirks but has to be set up and tested !!// | ||
| 31 | |||
| 32 | * **data analysis needs** | ||
| 33 | ** Do you need HDF5 files for your (semi-online) analysis during the beamtime. | ||
| 34 | ** Which parameters do you need for your (semi-online) analysis ? | ||
| 35 | ** how do you want to do analyze your data ? Can we find scripts from other users serving most of your needs? explain the FAB framework that helps analyzing data in advance | ||
| 36 | ** How much computational power will the analysis need (can we use the analysis servers at the beamline or do we have to use more powerful ressources) ? | ||
| 37 | * **Data access after the beamtime:** | ||
| 38 | ** data recorded with the FLASH DAQ will have to be moved to a long time (tape) storage few month after the beamtime. During / shortly after the beamtime it has to be decided where to put the locally recorded data. | ||
