The LCLS provides a number of tools that allow users and staff to participate remotely in experiments while access to the site is restricted due to COVID-19 safety protocols. These were demonstrated in the LCLS User Town Hall held on July 23, 2020, and available at this link. This page will provide an overview of tools for external (incl. users) and internal (staff only) use, and provides links to pages with additional details such as installation and usage guides, as well as minimum system requirements.
The LCLS provides a number of internally developed and 3rd party tools to share information before, during, and following an experiment. At all times during the process, the spokesperson and collaborators should continue to communicate directly with their assigned LCLS Point of Contact, and use the standard tools such as the Experiment Questionnaire and Electronic Log Book of Experiment, "eLog", (links below).
In addition to these historical tools, the LCLS provides video-conferencing capabilities through zoom, and high definition, read-only, screen sharing through video streaming.
Network Speed-test
Before your beam-time, perform a Network Speed Test to verify the speed of your network connection to SLAC, and fill out the associated survey while testing out the other tools listed below.
The LCLS will provide real-time interactive video conferencing on the zoom platform. The meeting ID and password will be provided within the eLog for each group, to maintain the privacy of each collaboration.
Description, Stanford site license, passwords, distribution (via eLog or email), live plots of AMI (camera images, histograms, etc.)
Link to download and install
via zoom for each experiment. For details, please refer to our Zoom User Guide.
In order to provide read-only viewing of multiple control-room displays at full resolution, without impacting the performance of the host machine, LCLS is working to provide a Video Streaming Service for multiple control-room displays at each instrument.
LCLS Offers a pool of NoMachine hosts that serve as an entry-point to efficient X11 access to our computing resources for interactive and offline analysis and general computing. Please see the Remote Visualization user guide for more information.

Electronic log book of experiment (updated - new and improved for Run 18)!
We have prepared a Remote-Access Reporting Tool so users and staff can report the result of their testing with the tools described herein, which have significant network bandwidth requirements. Please share your results with us so we can improve these services for the entire LCLS community.
Internally, we are using or developing additional remote access tools. They are described here for information purposes. If you believe your experiment would benefit from the use of these tools, contact your LCLS experiment Point of Contact to discuss.
Stanford University maintains an enterprise license to the slack chat application. Guests from other facilities Here is the getting started guide from University IT. External guests from can be added to specific channels upon request and LCLS agreement, discuss with your LCLS Point of Contact.
To support remote operations a dedicated NoMachine Terminal Server has been deployed: psnxopr.slac.stanford.edu.
Then, NoMachine Enterprise Desktop will be installed on all DAQ workstations.
The following link provides guidelines to configure NoMachine Client: Remote Visualization.
To access the DAQ workstation, use the following steps:
At times it may be necessary for offsite staff to collaboratively share control of an instrument control workstation with onsite staff. This capability is provided by the NoMachine Physical Desktop service. Access is granted and continued at the discretion of the onsite operator of the target workstation.
LCLS has acquired a number of augmented reality headsets of Remote Collaboration Headsets to allow staff technicians and engineers to co-view a workspace while respecting social-distancing protocols.
Hardware: https://www.realwear.com/products/hmt-1/
Software: https://www.amaxperteye.com/
We are using Space1 as the software platform for communicating with the AR headset.
Login here to call the headset and use the communication tools:
Login for operator:
Help1@slac.stanford.edu Help1!
Login for headset (Virtual collaboration – Space1)
User3@slac.stanford.edu User3!
Within the call you can,
We were able to establish calls from psconsole to the headset over EDUROAM wifi in the FEH.

LCLS has acquired a number of Remote Presence Robots which we are evaluating for use in experimental areas while the beam is active and personnel-access is restricted.
...
One of the units is enabled in developer mode, this allows development work with the base Unix environment that the robot is running on, as well as full access to the programming of the robot drive, and detectors.
Potential development features include:
