What to do before the Beamtime?

Project leaders/PIs have to contact the assigned local contact at DESY Photon Science well in advance to clarify any experiment-related question and to allow local staff to prepare the experimental stations in time. This will help to ensure that users can make best use of the beamtime allocated for their experiment.

Tasks of the Proposal Principal Investigator (PI)

at least 4 weeks before your arrival at DESY for the experiment the principal investigator (PI) has to log in to DOOR and

  • register all experimenters for onsite/remote participation or data only (=access to experimental data)
  • fill in the "Declaration of Substances and Apparatus"
  • register the use of lasers (if applicable)
  • fill in the "Request for the Use of the Chemistry Laboratory" (if applicable)
  • upload safety concepts as part of the before mentioned declarations
  • requests for special gases, chemicals or equipment have to be communicated to your local contact as soon as possible. The delivery of special or high purity gases as well as gas mixes may require delivery time up to 12 weeks
  • apply for travel reimbursement (via DOOR) (if applicable)

Tasks of each participating experimenter

Please do not forget to

  • book accommodation in DESY Hostel
  • bring your DACHS card obtained during an earlier visit to DESY
  • In order to get acquainted with the DESY safety regulations, each user has to complete the online safety training prior to the start of the experiments, preferably well before your arrival on site. The online training is accessible via the DESY Online Office for Research with Photons DOOR. After completion of the online training course the printed and signed certificate has to be send via email to door@desy.de
  • In addition to the appropriate online instructions via DOOR, all experimenters have to participate in the respective on-site instructions for their work task/area (e.g. beamline hutches, laboratories). The on-site instruction at the beamline has to be arranged with your Local Contact.
  • For User Chemistry Laboratory access and appointment for the on-site safety instruction please consult the webpage.
  • You will find more detailed safety information (gas handling, etc.) on the DESY Photon Science infrastructure pages.
  • In case you carry samples personally to and from DESY, please inquire for effective regulations and required official documents at your home institution. Please note that there are special safety regulations for flights.
  • In addition, please check your medical insurance and liability insurance coverage before your stay at DESY Photon Science, especially if you come from a non-European country ( the DESY welcome services - international office provides further information)
  • If you need a visa for Germany, please keep in mind that you must apply for a visa as soon as possible but at least 6 - 8 weeks before your expected departure for Hamburg. In some countries, e.g. India, the procedure may even take longer. As soon as the beamtime is scheduled, the PI of the proposal has to register all particpants for the experiment. After registration you can apply for the supporting invitation letter via DOOR. Login as General User and then select Preparation of scheduled beamtimes/experiments-->Visa - invitation letter.
