The OCTOPI (Operando Computed TOmographic & Ptychographic Imaging) upgrade of the I13L beamline will occur as one of the selected (flagship) projects at Diamond Light Source, UK.
The beamline I13L is dedicated to multi-scale, operando and high-throughput imaging. Two independent branchlines cover the micron to nano-resolution range, operating in the energy of 6-30keV. For operando imaging comparable recording times across the different length scales is important for studies under similar experimental conditions in terms of temporal resolution or number of specimen measured.
Progress in throughput and data acquisition speed is achieved in different ways. A sample throughput of up to 300 samples a day is achieved for micro-tomography, using an automated sample changer. For imaging with grating interferometry and the full-field microscope, broadband radiation of the undulator source can be used. The bandpass is selected either with a multilayer monochromator or with filters and a mirror. Highest spatial resolution is achieved with ptychography, acquiring data with 10kHz speed and recording tomographic data sets within few hours. Across the different length scales, the gap between the recording times will be significantly reduced and permit multi-scale imaging on a similar number of specimen and time scales.
We will discuss the aims of the upgrade and the science to be addressed. The design and layout options for the upgrade will be discussed.
