Cosmic Microwave Background measurements play a key role in the exploration of the cosmic frontier. The remarkably high degree of isotropy in the CMB led to the inflation theory for the origin of our universe, through exponential expansion of quantum fluctuations at the GUT energy scales. Further CMB measurements showed the curvature of the universe is flat and that the distribution of the...

This paper describes two aspects of the current R&D programme towards upgrades of the CMS trigger and detector readout systems. We show that the adoption of modern hardware and software components, in non-traditional architectures, can bring improvements in cost, reliability and flexibility.

Solid-state photomultiplier (SSPM) arrays are an interesting technology for use in PET detector modules due to their low cost, high compactness, insensitivity to magnetic fields, and sub-nanosecond timing resolution. However, the large intrinsic capacitance of SSPM arrays results in RC time constants that can severely degrade the response time, which leads to a trade-off between array size and...

The branching ratio (BR) for the decay K+ -> pi+ nu anti-nu is about 10-10 and can be predicted in the Standard Model with minimal theoretical uncertainties, making it a sensitive probe for new physics. Measurement of this BR is challenging because of the background from dominant channels. The goal of the NA62 experiment is to measure this BR to within about 10%.

Fast digital multi-channel analyzers (FDMCA) which base on flash ADC have been intensively used recently. The principle of FDMCA is different from the traditional MCA which based on the Wilkinson ADC. The non-linearity, including the INL and DNL, arising from flash ADC, degraded the accuracy of FDMCA. To improve the non-linearity of fast digital MCA, a practical off-line correction method has...

KM3NeT is a future deep-sea Research Infrastructure hosting a cubic kilometre-scale neutrino telescope and facilities for marine and earth sciences in the Mediterranean Sea. The consortium is made up of 40 institutes from 10 European countries, and includes all the groups that have developed the pilot projects, ANTARES, NEMO and NESTOR.
The KM3NeT telescope will consist of a three-dimensional...

A new detection system performing coincidence measurements by a calorimeter (WILLI) and a small array of 12 scintillator stations has been installed in NIPNE-HH, Bucharest, Romania. The aim of the system is to investigate the muon charge ratio within extensive air-showers by using the mini-array as trigger for the time sensitive WILLI calorimeter, which is able to reconstruct the muon charge...

A new type of low density, thermally conducting carbon foam has been developed for fabrication of low-mass support structures for silicon pixel and silicon strip detectors. The properties of the foam will be described. Prototype structures using the carbon foam have been constructed and tested. Mechanical and thermal measurements will be presented. Results after extensive thermal cycling and...

TileCal is the hadronic calorimeter of the ATLAS experiment at LHC/CERN. The system contains roughly 10,000 channels of read‐out electronics, whose signals are gathered and digitized in the front‐end electronics and then transmitted to the counting room through two redundant optical links. Then, the data is received in the back‐end system by the Optical Multiplexer Board (OMB) 9U which...

Tracking and identification of jets originating from b quarks (b-tagging) will likely continue to be a key element of many physics analyses at the upgraded HL-LHC where much higher pileup can significantly reduce the performance. An upgrade of the CMS pixel detector proposed for the Phase 1 HL-LHC should enable CMS to maintain the current level of b-tagging performance even in the presence of...

The ATLAS experiment at the LHC is equipped with a charged particle tracking system, the Inner Detector, built on three subdetectors, which provide high precision measurements made from a fine detector granularity. The Pixel and microstrip (SCT) subdetectors, which use the silicon technology, are complemented with the Transition Radiation Tracker.
In this talk, the performance of the track...

The need of applying large electrical potential differences between thin long wires imposes some of the tightest requirements in the design of modern multi-wire proportional chambers (MWPCs) [1] and similar in Geiger-Müller-like tubes. Relatively high stretching forces are needed to ensure a stable equilibrium of the wire positions [2]. Moreover the sensitivity to (random) event-related...

Poster Presentation
We present the results of verifing focusing system for Time Of Propagation(TOP) counter.
The TOP counter is a new detector of particle identification(PID) for burrel region of BelleII.
TOP counter is a kind of Ring Imaging Cherenkov counter(RICH) which detect internally reflected Cherenkov light like DIRC.
MCP-PMTs, which are compornent of TOP counter, detect ~20 Cherenkov photons per...

We are using DRS4 digital oscilloscope board for time-of-flight (TOF) applications in Fermilab. We developed a model to perform waveform analysis of the DRS4 data taken with silicon photomultipliers. The applications range from Cherenkov TOF system to TOF positron emission tomography. The unified approach allows to achieve high time resolution for signals with width from few to hundreds nanoseconds.
