For over three Earth years, two intrepid robotic explorers, Spirit and Opportunity, have been successfully conducting field geology day after day on Mars at two distinct locations on the surface. Originally designed for a 90-Martian day mission, the rovers have exceeded that requirement by a factor of 12 and show no signs of stopping. As the rovers move, each day becomes a brand new mission with new sights and new geology to explore. Both rovers have made significant discoveries in understanding the Red Planet, but great adventures still lie ahead for each rover.

One and a half years after installation of the first components, much progress has been made in commissioning of the accelerator for the clinic in Heidelberg. In the final state it is designed to produce different kinds of heavy ions with energies up to 430 MeV/u to treat about 1300 tumor patients a year at three therapy rooms. Presently the specified parameter space for patient treatment is filled to meet the correct combinations of energies, beam foci, and intensities for the therapy. In this contribution we will first shortly describe the concept of the control system which was designed by GSI but developed by an all-industrial partner who furthermore delivered the front-end control units and has another contract with Siemens Medical Solutions to meet the requirements at the interface to the therapy control system. We will mainly focus on its abilities and experiences with it: different kinds of beam requests, time accuracy, real-time analysis, assurance of consistent device data, offline-diagnostics and the beam diagnostic systems. We also report on known restrictions and the concept to securely provide different operation modes for accelerator adjustment or patient treatment.

The X-ray FEL project at SPring-8 aims to build an X-ray lasing facility, which will generate brilliant coherent X-ray beams with wavelength of below 0.1nm. A combination of short-period in-vacuum undulators and an 8GeV high-gradient C-band linear accelerator makes the machine compact enough to fit into the SPring-8 1km-long beamline space. The machine commissioning will be started by March 2011. We designed the control system for the new machine based on the present SCSS test accelerator, which employs the MADOCA framework. The control system is based on the so-called “standard model” and composed of Linux-based operator consoles, database servers, Gigabit Ethernet, VMEbus system, and so on. The control system, also, has a synchronized data-taking scheme to achieve beam-based optics tuning. Most of the device control part is installed in water-cooled 19in. racks together with RF devices for temperature control, which guarantees stable RF phase control. This paper gives an overview of the project and describes the design of the control system. In addition, we briefly report the status of the SCSS test accelerator operated as a VUV-FEL user facility.

Status of the FLASH Free Electron Laser Control System

FLASH (Free electron LASer in Hamburg) is the first facility based on the 1.3GHz superconducting cavity technology. It is a test bed for this technology to prepare future accelerators like the XFEL and ILC. Since 2005 FLASH has run as a reliable FEL source for user experiments. The control system DOOCS (Distributed Object-Oriented Control System) provides the required full bunch resolution of the diagnostics. A fast DAQ (Data AQuisition system) has successfully been integrated to support slow feedback, diagnostics, and data recording for both the linac operation and the user experiments. The control system will be slowly upgraded to implement the further requirements for the XFEL.

Starting with the Linac in 2005, the commissioning of the Diamond Light Source accelerators and photon beamlines, together with their related control systems, progressed to an aggressive program such that as of early in 2007, the facility was available for first users with a suite of beamlines and experiment stations. The implementation and commissioning of the control system to meet the overall project objectives are presented. The current status of the control system, including ongoing developments for electron-beam orbit stability and future photon beamline requirements, are also described.
