Opis:
Gamma and neutron radiation is produced during the normal operation of linear accelerators like Free-Electron Laser in Hamburg (FLASH) or X-ray Free Electron Laser (X-FEL). Gamma radiation cause general degeneration of electronics devices and neutron fluence can be a reason of soft error in memories and microcontrollers. X-FEL accelerator will be built only in one tunnel, therefore most of electronic control systems will be placed in radiation environment. Exposing control systems to radiation may lead to many errors and unexpected failure of the whole accelerator system. Thus, the radiation monitoring system able to monitor radiation doses produced near controlling systems is crucial. Knowledge of produced radiation doses allows to detect errors caused by radiation, schedule essential replacement of control systems and prevent accelerator from serious damages. The paper presents the project of radiation monitoring system able to monitor radiation environment in real time.

Opis:
Modern Advanced/Micro Telecommunications Computing Architecture (ATCA/žTCA) standards gain popularity, not only in telecommunication industry, but also in High Energy Physics (HEP) area. These platforms are considered as the future platform for the Low Level RF (LLRF) control system of the X-ray Free Electron Laser (XFEL) project realized at Deutsches Elektronen-Synchrotron (DESY) facility. One of the most important features of an ATCA/žTCA based control system is its high reliability, which can be decreased by negative influence of neutron and gamma radiation produced during normal operation of linear accelerators. The XFEL laser will be built in a single tunnel to decrease costs of the project. Therefore, the LLRF system will be exposed to harmful radiation. It is recommended to monitor doses absorbed by electronic equipment. The gathered data could help to estimate lifetime of electronic devices and to schedule essential equipment replacement. The radiation detector should be integrated with the ATCA/žTCA system to allow measurements in close proximity to the electronisc, which helps to increase the accuracy of measurements. The paper describes a radiation monitoring module capable of monitoring gamma radiation and neutron fluence in real-time which fulfills the mentioned requirements and is designed in accordance with the AMC specification.

Opis:
PCIExpress architecture is widely used communication bus designed, among other things, for industrial application. Additionally, according to PICMG 3.4 specification it is part of an ATCA architecture. For that reason PCIExpress was used as communication interface for data transmission between ATCA carrier boards and AMC modules for the new control system for XFEL linear accelerator. In this paper authors present general overview of this system, describe communication protocols designed to exchange data with external user application and show results of performance test.

Opis:
Pulsed operation of high gradient superconducting radio frequency (SCRF) cavities results in dynamic Lorentz force detuning (LFD) approaching or exceeding the bandwidth of the cavity of order of hundred of Hz. The resulting modulation of the resonance frequency of the cavity is leading to a perturbation of the amplitude and phase of the accelerating field, which can be controlled only at the expense of RF power |1-3|. The X-Ray Free Electron Laser (X-FEL) accelerator, which is now under development in Deutsches Elektro wen-Synchrotron (DESY), will consists of around 800 cavities with a fast tuner fixture including the actuator / sensor configuration. Therefore, it is necessary to design a distributed control system which could be able to supervise around 25 RF stations, each one comprised of 32 cavities. The Advanced Telecommunications Computing Architecture (ATCA) was chosen to design, develop, and build a Low Level Radio Frequency (LLRF) controller for X-FEL. The already performed tests of ATCA LLRF control system proofed the possibilities of usage of such a standard for high energy physics experiments |4|. The paper presents the concept of integration of the piezo compensation system to the ATCA standards with special emphasis to the hardware part of the system. Moreover, the first results from carried out tests of the prototype power supply unit for piezo drivers integrated to ATCA board will be presented.

Opis:
Future RF Control systems will require simultaneous data acquisition of up to 100 fast ADC channels at sampling rates of around 100 MHz and real time signal processing within a few hundred nanoseconds. At the same time the standardization of Low-Level RF systems are common objectives for all laboratories for cost reduction, performance optimization and machine reliability. Also desirable are modularity and scalability of the design as well as compatibility with accelerator instrumentation needs including the control system. All these requirements can be fulfilled with the new telecommunication standard ATCA when adopted to the domain of instrumentation. We describe the architecture and design of an ATCA based LLRF system for the European XFEL. Initial results of the demonstration of such a system at the FLASH user facility will be presented. Presented are the results of operating essential components of a prototype during the machine studies in January and March 2009.
