Sample environments available
Data analysis is supported through user training which is provided at the AINSE Neutron Scattering Winter School (http://www.ainse.edu.au/events2/winter_schools).
Data analysis for Taipan can be carried out for example with RESTRAX which can be found at http://neutron.ujf.cas.cz/restrax. It is specially designed for three-axis spectrometers (TAS) and is equipped with simplified (but faster) ray-tracing code for simulation of TAS resolution functions and additional tools for data analysis. It provides graphical representation of resolution functions as well as both simulated and experimental scattering functions. The non-linear least-squares fitting routine is available with variety of scattering models and a possibility to add other models created by users as a library linked dynamically to the main program. The program has been equipped with intuitive graphical user interface written in Java (portable across platforms).
For support, contact the Taipan instrument scientists: firstname.lastname@example.org
ANSTO promotes access to data collected during scientific experiments. See http://www.ansto.gov.au/ResearchHub/Bragg/Users/DataArchiving/index.htm
Access to data is available at ANSTO during the 3 year embargo period via the following options:
Login to https://tardis.nbi.ansto.gov.au where you can search through your data and download as required.
Access a secure copy at scp.nbi.ansto.gov.au using a client such as FileZilla (see http://filezilla-project.org/download.php) or winSCP (see http://winscp.net/eng/download.php).
If you are unable to login, contact the User Office email@example.com
It is ANSTO policy that after a 3 year embargo period, data becomes publicly accessible. This can be viewed as "Public Experiments" at https://tardis.nbi.ansto.gov.au. Metadata relating to the experimental data is copied to Research Data Australia http://researchdata.ands.org.au. In encouraging this practice ANSTO has helped many researchers forge new collaborations.
SpICE and SICS
The instrument control program used on TAIPAN is SICS (SINQ Instrument Control System) from PSI. SICS is run as a server, with Gumtree as the client.
Prior to the installation of SICS/Gumtree, the instrument control program used was SpICE, which is still used on the cold-neutron triple-axis spectrometer, SIKA, at the Bragg Institute. The table below gives the correspondence between the two programs for the common operating functions. Many commands have additional keys that control the function or fix certain parameters. See the manuals for SICS and SpICE for further details. Most functions in SpICE can also be accessed via a graphical user interface; click on the individual commands for further details. A subset of the SICS functions can be accessed via the Gumtree graphical user interface, and these are indicated in the right-hand column.
Both programs treat all moveable quantities (e.g. physical motors, sample-environment parameters, reciprocal-space and energy parameters) as motors, i.e. the values can be read, driven, and scanned.
