The Mu2e experiment at Fermilab is a search for muon-to-electron conversion in the field of an aluminum nucleus with a sensitivity improvement of four orders of magnitude over existing limits. The low mass straw tube tracker system and the pure cesium iodide crystal calorimeter system of the experiment will be discussed in detail.

An overview of the conceptual design and construction status of the detector for the MEGII experiment,
the upgrade of MEG, is presented.
MEGII is designed to search for the $\mu^+ \to e^+$ decay with a sensitivity an order of magnitude better than MEG
down to $5\times 10^{-14}$.
To achieve this sensitivity a muon decay rate a factor of two higher is required.
The detector resolution on...

The MEG experiment searches for the charged lepton flavor violating decay, $\mu^{+}\rightarrow$ $e^{+}\gamma$. MEG has already determined the world best upper limit on the branching ratio $BR<4.2\times10^{-13}$@90%CL.
An upgrade of the whole detector has been approved to obtain a substantial increase in sensitivity. Currently MEG is in upgrade phases, this phase involves all the detectors....

The cylindrical drift chamber (CDC) of COMET Phase-I experiment aims to search 105MeV electrons from muon-e conversion. To achieve the target sensitivity and high momentum resolution, CDC is designed and constructed to be a low-mass detector with alternating stereo layers. And a multi-track fitting method is introduced to meet the challenge of multi-turn track reconstruction in CDC.

The Central Drift Chamber (CDC) is the main device for tracking and identification of charged particles for Belle-II experiment. The Belle-II CDC is cylindrical wire chamber with 14336 sense wires, 2.3m-length and 2.2m-diameter. The wire chamber and readout electronics have been completely replaced from the Belle CDC.
The new readout electronics system must handle higher trigger rate of 30kHz...

The NA62 experiment at CERN is aimed at measuring the ultra-rare decay K+→π+νν̄ with 10% accuracy. The spectrometer contains 7168 straw tubes operating in vacuum. The detector was successfully installed and commissioned in 2014 - 2015. The goal of this report is to give a general overview of the straw tracker.

The Muon Drift Tube (MDT) chambers provide very precise and reliable muon tracking
and momentum measurement in the ATLAS muon spectrometer. Already in run 2 of the LHC
they have to cope with very high background counting rates up to 500 Hz/cm2 in the inner endcap layers. At High-Luminosity LHC (HL-LHC), the background rates are expected to increase by almost a factor of 10. New small (15...

In the PANDA experiment, for momentum analysis of forward scattered charged particles,
a large gap dipole magnet and the Forward Tracker (FT) will be used.
The main requirements for the FT include a high rate capability corresponding to particle fluxes
reaching up to $2.5x10^4 cm^{-2} s^{-1}$ close to the beam pipe and a total counting rate of about $5x10^7 s^{-1}$.
A momentum...

Significant R&D on detectors for the future International Linear Collider (ILC) has been carried out during the last few years. The ILD central tracker includes a Time
Projection Chamber (TPC) embedded in a 3.5 T solenoidal field.
Within the framework of the LCTPC collaboration, a Large Prototype (LP) TPC has been built
as a demonstrator. Its endplate can accommodate up to seven modules of...

STAR is upgrading the inner sectors of the STAR Time Projection Chamber(iTPC) to increase the segmentation on the inner pad plane from 13 to 40 pad rows and to renew the inner sector wire chambers. The upgrade will expand the TPC's acceptance out to pseudo-rapidity |eta| ≤ 1.5, compared to the current limitation of |eta|≤ 1. Furthermore, the detector will have better acceptance for tracks with...

CLIC is a proposed linear e$^+$e$^-$ collider providing particle collisions at center-of-mass energies of up to 3 TeV.
The physics objectives of precise top quark, Higgs boson and Beyond Standard Model physics require a superior performance of the CLIC detector.
In particular the vertex detector faces the challenges of providing a single point resolution of only a few micrometers while not...

The CMS experiment features as its innermost component a silicon pixel detector which provides high precision space point measurements of charged particle trajectories. The original detector was designed for an instantaneous luminosity of $1.0 x 10^{34} cm^{-2} s^{-1}$. Due to improvements of the LHC this luminosity was already exceeded in 2016 and it is foreseen that it will be further...

In 2016 the ATLAS collaboration successfully installed a part of the ATLAS Forward Proton (AFP) detector to measure diffractive protons leaving under very small angles (hundreds of micro radians) the ATLAS proton-proton interaction point. The AFP aims to tag and measure forward protons scattered in single diffraction or hard central diffraction, where two protons are emitted and a central...

The PANDA experiment will be part of the new FAIR accelerator center at Darmstadt, Germany. It is a fixed target experiment in the antiproton storage ring HESR. Main topics of the PANDA physics program are the search for new and predicted states and the precise measurement of the line shape by the energy scan method. Crucial for these measurements is the precise determination of the luminosity...

Mu3e is an experiment searching for charged lepton flavor violation in the rare decay $\mu \rightarrow $ eee.
Decay vertex position, decay time and particle momenta have to be precisely measured in order to reject both combinatorial and physics background.

The LHCb detector will be upgraded during the Long Shutdown 2 (LS2) of the LHC in order to cope with higher luminosities and to read out the data at 40MHz using a trigger-less read-out system. Several sub-detectors must be either redesigned or completely replaced to cope with higher occupancy. The current tracking detectors downstream of the LHCb dipole magnet will be replaced by the...
