The increase of the luminosity in the High Luminosity upgrade of the CERN Large Hadron Collider (HL-LHC) will require the use of Tracker information in the evaluation of the Level-1 trigger in order to keep the trigger rate acceptable (i.e.: < 1MHz). A custom real-time system will be needed to extract the track information within the latency constraints (<10usec). We developed the prototype...
We present the results of a survey of water maser emission at 22.2 GHz towards a selected sample of IRAS-PSC sources which are believed to be associated with very young massive stars. The sample consists of 591 sources. The observations have been carried out using the Medicina 32-m radiotelescope, operated by the Istituto di Radioastronomia - C.N.R., Bologna. Whereas previous searches for maser...
An overview is given of the analysis of more than a decade of H2O maser data from our monitoring program. We find the maser emission to generally depend on the luminosity of the YSO as well as on the geometry of the SFR. There appears to be a threshold luminosity of a few times 104 Lʘ above and below which we find different maser characteristics.
The increase of luminosity at High Luminosity LHC will require the introduction of tracker information at Level-1 trigger system for the experiments to maintain an acceptable trigger rate to select interesting events despite the one order of magnitude increase in the minimum bias interactions. To extract in the required latency the track information a dedicated hardware has to be used. We present...
Pixel detectors at HL-LHC experiments or other future experiments are facing new challenges, especially in terms of unprecedented levels of radiation and particle flux. This paper describes the progress made by the CHIPIX65 project of INFN for the development of a new generation readout ASIC using CMOS 65 nm technology.
The CDF associative-memory device, AM, proven technology developed for the Silicon-Vertex-Trigger at the CDF experiment, is one of the proposed solutions at CMS for track reconstruction at Level-1 in the Super-LHC very high-luminosity conditions (100 proton-proton collisions every 12.5 ns, at 1035 cm-2 sec-1). This luminosity requires a drastic revision of the existing trigger strategies. SVT is the...
