Why is it in the archive?
Due to the large volumes of data collected at Diamond each day, data is only guaranteed to be stored on disk for 40 days after your experiment. Older data is archived to tape.
Data older than 40 days cannot be accessed directly from the data directories on the beamline. Instead data should be retrieved from the Diamond archive via TopCAT. Login to TopCAT or for more help, go here
Once a request to retrieve your files has been sent to TopCAT, it will read through the archive and gather the files you need into a holding area until you are able to download them to your own system(s).
Was your session less than 40 days ago?
Your data will still be on the Diamond file system
