At present, part of the forward RPC muon system CMS detector at CERN LHC remains uninstrumented in high-η region. An international collaboration is investigating possibility covering 1.6 < |η| 2.4 region endcaps with large-area triple-GEM detectors. Given their good spatial resolution, high rate capability, and radiation hardness, these micro-pattern gas detectors are an appealing option for simultaneously enhancing tracking triggering capabilities a future upgrade detector. A general...

GEM detectors are used in high energy physics experiments given their good spatial resolution, rate capability and radiation hardness. An international collaboration is investigating the possibility of covering 1.6 < |η| 2.4 region CMS muon endcaps with large-area triple-GEM detectors. The high-η area actually not fully instrumented, only Cathode Strip Chamber (CSC) installed. vacant presents an opportunity for a detector technology able to cope harsh environment; these micropattern gas...

Gas Electron Multipliers (GEM) are an interesting technology under consideration for the future upgrade of forward region CMS muon system, specifically in 1.6 <; |η| 2:4 endcap region. With a sufficiently fine segmentation GEMs can provide precision tracking as well fast trigger information. The main objective is to contribute improvement trigger. construction large-area GEM detectors challenging both from technological and production aspects. In view we have designed built largest full-size...
The article describes the algorithm of finding highest transverse momentum muon based on signals from fast RPC detectors in CMS experiment at LHC collider CERN (Geneva). Very progress FPGA performance makes it possible to build Pattern Comparator Processor (PAC) using this technology. Compilation and simulation different configurations PAC are discussed. Improved which requires smaller resources FPGAs is presented.
The results of proton radiation test electronic devices for RPC trigger system CMS detector are presented. For Xilinx Spartan-IIE FPGA the cross section Single Event Upsets (SEUs) in configuration bits was measured. dynamic SEUs flip-flops also investigated, but not observed. FLASH memories no single upsets were detected, after a huge dose permanent damages SDRAM memories, SEU A brief description inducted effects FPGAs, SRAM and is
The CMS L1 Trigger electronics are composed of a large number different cards based on the VMEBus standard. majority system is being replaced to adapt trigger higher collision rates LHC will deliver after LS1, first phase upgrade program. As consequence, software that controls, monitors and tests hardware need be re-written. upgraded consist set general purpose boards similar technology follow TCA specification, thus resulting in more homogeneous system. A great effort has been made identify...
This paper describes the design of Link Box Control System for RPC Detector (RLBCS), emphasizing features needed to assure reliable operation in irradiated environment detector and its neighbourhood. The development process required balance different factors - radiation hardness, reliability, flexibility, firmware upgrade possibilities, diagnostic features. final presented is a result compromise between above requirements.
This paper presents a FPGA based DSP system for realtime simulation of superconducting accelerator's cavity. The linacs require sophisticated control systems maintaining the constant amplitude and phase accelerating field in cavities. debugging these on real hardware can be both difficult dangerous. To allow testing LLRF time with different cavity parameters, has been developed.

The CMS detector will start its operation in the end of 2007. Until that time great care must be taken order to assure hardware is fully understood. In this paper an example how emulation software helps achieving goal Level-1 RPC Trigger system presented. design trigger allows insert sets so-called test pulses at any stage pipeline. Reading out data from different stages also possible. Such for easy debugging by comparing and values, since algorithms are identical.
