The Powder Diffraction beamline offers a rapid access mail-in service for powder samples in capillaries at ambient conditions. This service should not be used as a replacement for merit access that is available 3 times per year.

Commercial users cannot use the mail-in service and need to contact the beamline staff directly at: as-pd@ansto.gov.au

Notes

  1. Groups can only submit 1 proposal per round.

  2. There is a maximum of 20 samples or a 3 hour shift (whichever is smaller), per group per round. Users requiring more samples or beamtime can submit a merit round proposal. The experiment may be cut short if it exceeds the permitted 3 h.

Example:

Q: Can I run 20 samples each at 30 min?

A: No, as the total time for the analysis will be ~10 h and there is a maximum of 3 h for an experiment

Q: Can I run 40 samples each at 4 min?

A: No, although the total time for the analysis is ~160 min and less than 3 h, there is a maximum of 20 samples for an experiment

(info) The PD team aim to run samples before the end of the merit round however this cannot be guaranteed as beamtime availability may be affected by unplanned beamline or machine problems.

Standard operating procedure (SOP)

Submitting a proposal

Users need to submit a short proposal in the Australian Synchrotron User Portal. Proposals can be submitted in the ~6 rapid access rounds offered per year, and are reviewed by our PAC. This proposal will require:

(info) The PD team are not responsible for delays in running samples due to the postal address being incorrectly provided by the user. 

Sample Box Kit

When your proposal is approved we will send you a sample box and pins to mount your samples. The sample box will be sent to the address nominated during proposal submission. Staff will confirm this address before shipping the box and will include a return address label.

Some users with a small number if samples may be asked to send us the samples directly and will not receive a box.

The kit that will be mailed to you will contain:

(blue star) Users are required to supply their own capillaries as the PD beamline cannot supply them.

(blue star) Please do not submit a proposal unless you have capillaries in time to prepare and send them back to us.

Experiment Authorisation

An Experiment Authorisation (EA) will need to be completed and approved before you return your sample box kit. There may be delays in measuring your samples if the box is returned before your EA is approved. The Australian Synchrotron cannot accept samples that are not associated with an approved EA.

A sample robot template needs to completed during proposal and EA submission. This requires the following to be input: sample box position, sample name, sample base/pin ID (printed on the base of the pin, i.e. PD201), number of positions (2), detector position 1 and 2 (difference of 0.5° 2θ), collection time (use the same for each detector position) and data file name. (blue star) The data file name cannot have spaces, or special characters.

Safety

The PD beamline will only accept low risk materials for mail-in. All hazards of your samples need to be disclosed in the EA form otherwise the experiment will be cancelled. We cannot accept any samples that are:

Sample Preparation & Mounting

Capillaries need to be 0.2-0.7 mm ID, and between 30 - 40 mm in length, as measured from the end of the pin. Larger ID capillaries cannot be sent as they are too fragile. The beam will be centered on the capillary 11 mm from the pin. Capillaries can be purchased from Charles Supper or Hilgenberg.

How to fill and mount a capillary

  1. Fill the capillary so that 45 mm of material is in the capillary.

  2. Break off the funnel, ensuring the capillary is ~45 mm in length.

  3. Insert the broken end of the capillary all the way into the sample pin.

  4. Melt a small amount of wax onto the capillary to fix it into position. Wax can be easily melted using a solder iron, or gas stove lighter. Check that the capillary is 30-40 mm, as measured from the end of the pin. (blue star) The robot will break capillaries longer than 40 mm.

  5. Use the cardboard protractor to align the capillary in the pin, and ensure the difference between the sample pin base and capillary is <5°. Capillaries will not align on the diffractometer and be run if the angle is >5°.

(info) The PD team can provide information and tips on sample preparation and mounting. We are not responsible for samples that cannot be run due to incorrect mounting, poorly filled capillaries or not enough sample in the capillary.

Sending Samples to the Australian Synchrotron

Please follow the instructions on how to send samples to the Australian Synchrotron. (blue star) All packages need to be addressed to the PD beamline and have the EA number clearly visible as without these there may be a delay in sample receival. There is a return shipping address included in the sample preparation kit. All samples need to be sent according to Australian and international transportation regulations.

(blue star) Only send samples when your EA has been approved otherwise they may be sent back to you

Only send samples when your EA has been approved

All samples must arrive at least 7 days prior to the date of scheduled beamtime otherwise they will be run during the following scheduled beamtime.

PD will check all sample pins have been returned, and all samples are labelled correctly when the sample box is received. (blue star) The samples will not be run unless all pins are returned.

(info) The PD team have to right to delay running samples if all samples pins are not returned to the AS.

(info) The PD team are not responsible for any capillaries that are received broken or capillaries that break during analysis.

(info) The PD team are not responsible for incorrectly labelled samples, or information incorrectly entered by the user into the robot spreadsheet.

Data Collection

Parameters for data collection need to be specified in the robot spreadsheet at the time the EA is submitted. These parameters cannot be changed once the EA is submitted.

All samples will be run using our robot at the next available beamtime.

After your Experiment

Beamline staff will email you with details on how the data was collected and how to access your data. Please remember to /wiki/spaces/PD/pages/399409224 in all publications!

Sample Disposal

All samples will be disposed of at the Australian Synchrotron.
