Optimised Multi-Dimensional Image Scanning With Rascan | |
|
||
| On-the-fly scanning has significantly improved one dimensional scans by removing motion overheads between pixels. However, realisation of multi-dimensional techniques such as tomography and XANES imaging is presently stymied by overheads that occur on a line-by-line basis. At the Australian Synchrotron's XFM beamline, inevitable "overheads" can add up to a significant wasted beam time. Therefore, there is a clear need for further optimisation of scan motion to formulate and minimise higher dimensional overheads. Here we outline our approach to realise trajectory scans that are optimised for trajectory tracking accuracy with minimised overhead times. The scan motion is seen as fly-scan lines, and overhead moves between the lines which form a two dimensional raster scan in a transformed geometry. This separation of 'required' and 'overhead' motions has provided an efficient platform for formulating an optimisation problem which is solved to obtain the optimised scan trajectory. The solution known as Rascan, is in operation at the XFM beamline of the Australian Synchrotron since May 2016, resulting in significant gains in throughput, performance and efficiency. | ||

Motion Control Workshop | |
|
||
| The ICALEPCS MOCRAF workshop group has been created on www. MOCRAF.org to discuss about the organization of the ICALEPCS Motion Control pre-conference Workshop. Its purpose is to get feedback from attendees to make the workshop as interesting and as pleasurable as possible. This group will remain alive after the workshop to be the input for the future ICALEPCS MOCRAF meeting. The aim of the workshop is to be helpful to you the community and so we welcome input (*) on the content and style. After the previous workshop in at ICALEPCS in Melbourne it was suggested that more time should be put aside for interactive group discussions. We are proposing two talks per session each of around 15 to 20 minutes leaving 50 - 60 minutes for relevant discussion topics. | ||
