BioSAXS construction

Information about construction:

• Works will occur on weekdays, 7 am to 3.30 pm. Some Saturday construction may take place.

• There will be various construction site safety instructions due to your proximity to the build; your onsite Beamline Induction will provide additional information.

• Your Beamline Scientist will introduce you to our Site Supervisor who will work with your team to minimise disruptions as much as possible. 

• Your Beamline Scientist will work closely with you to minimise the impacts of construction activities on your experiments as much as possible; one mitigation solution is appropriate timing of screening experiments vs dataset collection.

• In the event that construction activity degrades dataset quality on MX2, necessitating screening only before 3:30pm, there is an expectation that researchers within CAPS will organise their time in a collaborative and collegial manner.

Beam Stability Monitor:

If you are collecting on site, you’ll be able to hear drilling and heavy machinery, which could affect beam quality. If you are collecting remotely, however, you will need to open the Beam Stability Monitor to check whether construction is affecting the beam.

To open this, go to the Shutterflux controls interface and select ‘Beam Stability ’ (in soft blue here)

This will open this screen:

The black trace shows the vertical width of the beam, the stability of which is a good indicator of beam stability. If you see lots of vibration in this trace, consider screening rather than doing full data collections, or call your beamline staff for guidance.

The red trace shows whether the shutter is open or closed. Beam “stability” will jump when the shutter is being opened and closed. This is normal.
