Urgent user information during APS restricted operations
June 1, 2020
Urgent user information about APS and GM/CA restrictred operations for the 2020-2 run.
The APS is currently allowing only remote access or
mail-in data collection. However, the class of samples has been expanded
- Expedited access for research on SARS-CoV-2 or other COVID-19 related research
- Critical, proprietary pharmaceutical research
- Any research involving low-risk samples and most medium-risk samples
Please submit new proposals or beamtime requests at the
Users Information webpage.
To provide additional beam time for vital remote or mail-in
COVID-19 research, as well as for proprietary pharmaceutical-related
research, the APS has shortened its upcoming maintenance period to
June 1 - 9. Additionally, the late summer maintenance period has been
shifted to August 13 - September 14 in coordination with NSLS II so
there is no extended time where neither facility is operating, allowing
for uninterrupted x-ray access for COVID-19 research.
The revised 2020-2 schedule is: June 10 (8:00 am) -
September 28 (8:00 am). The current long range schedule can be found at the
APS Long-Range Operations-Schedule webpage.
In addition to providing expedited beamtime for vital
COVID-19 research, we are currently working on scheduling user groups
that we had to cancel during the 2020-1 run, as well as those who
originally applied for beamtime during the 2020-2 run.
March 23, 2020
The APS and GM/CA continue to operate, providing expedited, remote
access but only for research related to COVID-19 at this time.
Step-by-step instructions on how to apply
for expedited beam time are listed on the
APS New User Checklist. All users must be
registered and their home institution must have an active User Agreement.
Please submit a Rapid Access proposal and state that the research is
related to SARS CoV-2 proteins or COVID-19. The Experimental Safety
Approval Form (ESAF) should also indicate SARS CoV-2 or COVID-19.
Please do not send any Dewars to us, except those
related to COVID-19 research until further notice.
March 21, 2020
Following the Illinois Governor's stay-at-home order, the APS further
limited operations beginning at 5 PM Saturday March 21. The situation
with respect to remote access is currently in flux, and only SARS-CoV-2
studies being continued for certain. We will use this space to provide
update information as soon as it becomes available.
Urgent user information related to COVID-19
GM/CA @ APS offers
immediate beam time for SARS-CoV-2 studies
In response to the urgent need for more data on SARS-CoV-2,
the coronavirus that causes COVID-19, GM/CA @ APS will offer nearly
immediate beam time to user groups working on SARS-CoV-2. Contact GM/CA at
for special access beam time. With the sophisticated GM/CA remote access
capability, there is no need to travel to screen samples and collect data.

GM/CA @ APS is
temporarily switching to all-remote operations
To minimize risk of COVID-2019 transmission and to
accommodate visitors with travel restrictions due to the pandemic,
Argonne National Laboratory has restricted visitor access to the Lab,
including those planning to visit and use the Lab User Facilities,
including the APS. GM/CA@APS has an excellent remote access program
used by more than 80% of user groups before the pandemic. Therefore we
do not anticipate any substantial inconveniences for our users with the
change. For those who did not use the GM/CA remote capabilities previously,
we encourage you to watch our video guides,
to visit our remote access webpage, and to
read remote access FAQ.

If you have remote-access beam time, please contact
your host before shipping samples. We will top up Dewars with liquid
nitrogen when they arrive, as usual, and will keep them in cryo
condition. However, we cannot hold and top up liquid nitrogen in Dewars
for many, many labs around the country. We will need to return your
Dewars regardless of the operating status of your lab. Before you ship
Dewars to us, we need information on returning Dewars in the event that
your lab is not in operation at that time.
