Joint Research Group Macromolecular Crystallography

Prepare for Remote Access Experiment

Please follow the required steps to prepare for a remote access experiment.



Remote Access Beamtime Booking

A prerequisite for remote access is a confirmed beamtime slot. Currently, we are offering remote access for 8-16h at BL14.1 and BL14.2, starting 09:00 am and 10.00 am Wednesday till Saturday, respectively. 

Please book your remote beam time using GATE. All GATE bookings are considered as a remote beam time access request. 

Please tick "remote experiment" within the GATE form to select the experimental team. This prevents all downstream processes like guesthouse bookings and dosimeter provision. 

Responsible Scientist for Remote Data Collection

Each remote data collection requires the designation of one responsible scientist. Please fill out the below form, 3-5 working days prior to your remote data collection date. Our user support will contact you and will provide you further information. 


Remote Access User Qualifications

To carry out successful remote experiments, the remote user shall have the following qualifications:

  • You have joined the remote user training (future offer), or you have already collected diffraction data at the respective beamline in person.
  • You have a valid rex_account, which designates you as the responsible scientist throughout the whole experimental beamtime.
  • We expect you to have a solid understanding of macromolecular X-ray crystallography, which enables you to plan and carry out your experiments independently. The remote user support helps you on a technical/scientific basis during your experiment, which mainly focuses on using our experimental infrastructure. 

If you do not meet the requirements, please refrain from proceeding. Instead, contact Manfred Weiss or the beamline scientists and ask for a scientific collaboration before the anticipated beam time. The terms and conditions will then be discussed depending on your individual needs.


Remote Access Credentials

Prior to the remote access beam time, you will be granted a so called "rex_account", which enables you to access our beamline intranet via the NoMachine Server foris.helmholtz-berlin.de. The rex_account is still valid after your experiment, so please safe a credentials data.

This account is allowing access from 07:00 am at the day of the experiment.

In addition, we will send you the PX-account credentials, which enables you to login into the beamline control computers and the zoom login for the meeting with your user support at 09:00 am of the day of your beamtime


Supported Sample Containers and Sample Holders

Sample containers:
Currently, we are only supporting Uni-pucks at BL14.1 and ESRF-pucks, also called SPINE pucks at BL14.2 only. 

Sample Holders:
Please make sure only to use specified sample holders. Please check through all of them according to our specifications, which can be found here:
Sample specifications


Dewar Shipment

Please send the dewars in good time prior to your beam time, which is for EU users 3 working days before the beam time.  
Please follow our instructions: Dewar shipment instructions
