Information about Instrument Control Programs

SINQ is using the Sinq Instrument Control Software (SICS) to control all neutron scattering instruments except radiography. Here is some user infromation about SICS.

User Documentation

• A document describing the design of the SINQ Instrument Control System (SICS).
• The powder diffractometers DMC and HRPT.
• The two circle diffractometer MORPHEUS.
• The small angle machine SANS and SANS2.
• The time-of-flight spectrometer FOCUS.
• The triple axis spectrometer TASP.
• The reflectometer AMOR
• The triple axis spectrometers RITA-2 and EIGER
• The new ZEBRA command set
• Search the SICS documentation.

SICS Troubleshooting page

Mobile Friendly Instrument Status

For some SINQ instruments there are mobile friendly WWW-pages which are updated any 15 minutes. There are:

• DMC
• HRPT
• POLDI
• EIGER
• BOA

The Virtual Powder Diffractometer VDMC

PSI is operating a virtual powder diffractometer for users to play with. The virtual powder diffractometer is modelled after the real powder diffractometer DMC. A McStas simulation provides the data generated during virtual data collection. Users can choose from a set of pre configured samples or upload a description of their own sample generated with the program Lazy Pulverix. VDMC is driven through an experimental executable manual style WWW user interface.

Conferences hosted on this WWW-server

• NOBUGS 2004
• A Monte Carlo Workshop for Neutron Scattering in 2006
• The 2010 NeXus for Synchrotrons Workshop

SICS Clients

The instrument control software SICS is accessed through special client software written in Java. The client programs are available on all instrument computers. Addionally they can be started from this very WWW server through the Java Web Start mechanism. More details about Java WebStart and installation instructions can be found on the If your computer has been set up properly you can directly start the SICS WebStart applications from the links below.

• The SICS Command Line Client
• The new SICS Batch Editor
• The SICS Variable Watcher
• The NeXus Network Data Browser
• The AMOR Client
• The AMOR Status
• The FOCUS Application
• The Powder Diffraction Status Display
• The SANS Status Display
• The Scan Status Display for MORPHEUS, NARZISS, ORION or any other scanning instrument.
• The Triple Axis Application
• The TRICS Application.

SICS World Wide Web Instrument Status

View Instrument Status Information. No java or other browser specialities required. Some textual information and a characteristic graphics of the current experiment will be displayed.

Other Manuals

• FullProf : Rietveld Refinement (powder and/or single crystals).
• Documentation for the PGPLOT graphics subroutine library. Access possible only from within PSI.
• The Anatric manual. Anatric is a program for integrating intensities from four circle PSD files.
• The LNS Unix Basics manual in PDF format. This is an introduction for new LNS/LDM staff about the Unix environment at PSI and SINQ. It also gives a brief introduction to Unix for those unfortunate people who never learned about Unix.
• A local copy of the Edinburgh Unix User Pages.
• Linux man-pages.

Computing Cluster

In order to support LNS/LDM staff in data analysis and for the MCNP and McStas simulations which are performed a computing cluster is provided. For more information follow this link.
