CAMERA Sponsored Workshops, Tutorials, Summer Schools


     CAMERA Workshop: Algorithms for Tomographic Reconstruction:

State-of-the-Art Future Goals: Nov. 9-11, 2016, Lawrence Berkeley National Laboratory

      Organizers: D. Parkinson (ALS-CAMERA), D. Gursoy (APR-Argonne), K. Champley (LLNL)

     This workshop will focus on the current state-of-the-art for tomographic reconstruction algorithms. The goal is to bring together users, practitioners, and developers to asses the current landscape of available algorithms, to investigate communalities and differences among the various techniques, and to discuss a range of topics, from required theoretical and algorithmic advancements on through to practical issues of implementation and deployment.

     We are bringing together developers and users of synchrotron tomography software. The workshop will have two kinds of talks:
   (1) Technical talks from developers to describe their current algorithms and capabilities, and their future potential.
   (2) Talks from users of tomography software to discuss successes and unmet needs, and to find common goals.

We plan to include ample time for discussion and hacking, with our software people available to help get software packages running on various computer systems at LBNL if developers so choose (including our high performance computer NERSC, our GPU clusters, and standard beefy workstations).  We are also happy to provide developers with access to a wide variety of challenging data sets--we have been archiving all raw data from the ALS hard X-ray tomography beamline for the past 5 years.

"GISAS summer school: experiments and analysis "

Organizers: Herzig Group: Munich School of Engineering (TUM MSE), Jülich Centre for Neutron Science (JCNS) and the Advanced Light Source (LBNL)

July 17, 2016 - July 27, 2016


   CAMERA Contact: A. Hexemer





This summer school invites Master students and PhD students to join with their own thin film samples suitable for grazing incidence small angle x-ray scattering (GISAXS) and grazing incidence small angle neutron scattering (GISANS) measurements. The unique program will consist of lectures on experiment design and scattering theory, necessary to understand the method and to choose experimental parameters. The x-ray experiments will be carried out remotely at the ALS, Berkeley, USA, while the neutron experiments will take place at the FRM II on site. Furthermore there will be practical sessions with introduction to data analysis tools (HipGISAXS and BornAgain) and tutorials in applying them, where each student will work on their own data. Overall, this summer school will prepare students to carry out grazing incidence experiments at large scale facilities including the relevant data analysis.

Novel, smart thin film materials are the focus of many research projects ranging from sensing to displays and from wireless communication to energy conversion and energy storage. These are all active research fields where understanding of material properties will lead to innovation. Although the list of resulting applications is very wide, all these novel materials have something important in common: the physical properties, and therefore the industrial usefulness, is closely related to the molecular and nano-morphology of these materials.

Therefore, methods of characterizing such thin film materials are needed. Grazing incidence scattering techniques have proven here to be very successful. With this method the morphology inside thin films can be probed on the nanometer scale – not just on small micron spots – but on macroscopic areas of the sample, yielding industrially relevant information.

To aid students to carry out successful grazing incidence scattering measurements this summer school will kick-start beginners and introduce new data analysis tools for students with scattering experience.

"MSRI-LBNL Summer course in Electronic Structure Theory".

Organizers: Lin Lin (UC Berkeley and LBNL), Jianfeng Lu (Duke University), James Sethian (UC Berkeley and LBNL)

July 18, 2016 - July 29, 2016


CAMERA Contact: L. Lin and J. Sethian




Ab initio or first principle electronic structure theories, particularly represented by Kohn-Sham density functional theory (KS-DFT), have been developed into workhorse tools with a wide range of scientific applications in chemistry, physics, materials science, biology etc. What is needed are new techniques that greatly extend the applicability and versatility of these approaches. At the core, many of the challenges that need to be addressed are essentially mathematical. The purpose of the workshop is to provide graduate students a self-contained introduction to electronic structure theory, with particular emphasis on frontier topics in aspects of applied analysis and numerical methods.

"Fundamental Tools for Data Scientists - SHELL, GIT, Python and SQL".

Training at the 2015 Software Carpentry Hands-on, May 4-7, 2014, Lawrence Berkeley National Laboratory. 

                                                    Instructors: D. Ushizima, G. Wilson, D.Winston


Data science is called "the sexiest job of the 21st century", according to market demands [link]. If this area is of utmost importance, why don't we have more courses at LBNL that address related skills? As a CAMERA co-PI and the UC Berkeley Data Scientist fellow at LBNL, D. Ushizima has supported initiatives such as Software Carpentry in order to help bring others up to speed on key data science knowledge.

"High Performance Software, Workflows, and Visualization for Synchrotrons".

 Workshop at the 2014 ALS User Meeting, October 7-8, 2014, Lawrence Berkeley National Laboratory.  


Organizers: Alexander Hexemer, Dula Parkinson, David Shapiro, Alastair MacDowell (ALS-LBNL), Craig Tull (CRD-LBNL)


           CAMERA Contact: A. Hexemer, D. Parkinson, D. Shapiro

Beamlines require robust, high performance software for analysis and visualization. This need is driven by high data rates and volumes, and by dynamic experiments where researchers must have feedback during beamtime. A flexible and highly customizable work flow framework could be used across many beamlines and synchrotrons. Beamline scientists and the user community could leverage this framework, making it significantly easier for them to provide high performance analysis tools to general users. This workshop will investigate the current state of the art in workflow, analysis, and visualization tools.

"CAMERA-SHARP real-time robust ptychographic imaging".  

Workshop at the 2014 ALS User Meeting. Wed. Oct 8, 9 am-5 pm, Lawrence Berkeley National Laboratory, Berkeley CA.

By combining diffraction with microscopy and the computational power of GPUs, one can quickly turn high throughput "imaging by diffraction" techniques into the sharpest images ever produced. Every scanning microscope can now add a parallel detector, and every diffraction imaging instrument can add a scanning stage to take advantage of this disruptive technique. To sustain high throughput processing (~>TB/h) the CAMERA collaboration has recently released a software suite for high throughput real time ptychographic data analysis which is freely available* and open for collaborative development. The workshop is intended to be accessible to new users who wish to learn about ptychographic imaging analysis, as well as experienced scientists wishing to learn more about available analysis tools for real-time analysis of murky experimental data. Live demonstrations and tutorials of the software packages will be performed where possible to help new users. We encourage participants to bring ptychographic data for demonstrations of the reconstruction process and to also present demonstrations of their own reconstruction methods. The workshop will be organized as a few brief morning talks followed by a long interactive tutorial session.
