Presently these accelerator facilities are operated with pulsed RF. In future, these facilities should be operated with continuous wave (CW) which requires significant modifications on the real-time feedbacks realized within the FPGA. For example, higher loaded quality factor of the cavities when operated in a CW mode requires sophisticated resonance control methods. However, iterative learning techniques widely used for machines operated in pulsed mode are not applicable for CW. In addition, the mechanical characteristic of the cavities have now a much more important impact on the choice of the feedback scheme. To overcome the limitations of classical PI-controllers novel realtime adaptive feed forward algorithm is implemented in the FPGA. Also, the high power RF amplifier which is an inductive output tube (IOT) for continuous wave operation instead of a klystron for the pulsed mode has major impact on the design and implementation of the firmware for regulation. In this paper, we report on our successful approach to control multi-cavities with ultra-high precision (dA/A<;0.01%, dphi<;0.02 deg) using a single IOT source and individual resonance control through piezo actuators. Performance measurements of the proposed solution were conducted at Cryo Module Test Bench (CMTB) facility.","PeriodicalId":383702,"journal":{"name":"2016 IEEE-NPSS Real Time Conference (RT)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123132842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently ATLAS is under Phase-I upgrade, which focus mainly on the Level-1 trigger system to maintain the full acceptance of muon tracking while discriminate against background and keep the Level-1 rate at an acceptable level.

The sTGC Level-1 pad trigger logic is implemented first single wedge pad trigger which is based on coincident hits in three out of four layers of a multiplet in each wedge independently and then pad trigger which is based on geometrical matching between the two wedge triggers in order to identify the interaction point (IP).

The feature extraction stage delivers event-filtered and bandwidth-reduced data to the First Level Event Selector (FLES). The feature extraction stage implements multiple processing algorithms in order to find and extract regions of interest within time series signals. Algorithms such as peak-finding, signal integration, center of gravity and time-over threshold were implemented for online analysis. On the other hand, a local clustering algorithm allows to find cluster members and to implement even further data reduction algorithms. A feature extraction framework for automatic firmware generation has been tested for the CBM-TRD data acquisition chain. The framework allows the generation of Field Programmable Gate Array (FPGA) designs that implement feature extraction algorithms. Such designs are FPGA-platform independent and are described by a file written in a Domain Specific Language (DSL). The result of using the mentioned feature extraction framework for the TRD feature extraction stage is presented and discussed.","PeriodicalId":383702,"journal":{"name":"2016 IEEE-NPSS Real Time Conference (RT)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132469795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
