The PHENIX Experiment at RHIC is planning a major upgrade that involves building an entirely new spectrometer based around the former BaBar solenoid magnet that will enable a comprehensive study of jets and heavy quarkonia in relativistic heavy ion collisions. It will include two new calorimeter systems, one electromagnetic and one hadronic, that will cover an acceptance of ±1.1 units in...

The prospective future Electron-Ion Collider (EIC) would offer a unique opportunity to understand the role of gluons in strongly interacting nuclear matter. An ambitious generic detector R&D program started in 2011 in order to address the scientific requirements for measurements at such a new facility. In particular, a dedicated consortium was created with the goal of developing new...

In high energy and nuclear physics experiments, total absorption electromagnetic calorimeters made of inorganic crystals are known for decades for their superb energy resolution and detection efficiency. Significant degradation of crystal performance, however, was observed in a severe radiation environment, such as the LHC. A very compact crystal based shashlik calorimeter was designed for...

After the discovery of the Higgs particle, Chinese high energy physics community has proposed circular electron positron collider (CEPC) as a Higgs factory and the pre-CDR has been released in May, 2015. The pre-CDR design of the CEPC detector will be presented and the status of Calorimeter will be focused.

The Mu2e experiment at Fermilab searches for the charged-lepton flavor violating
neutrino-less conversion of a negative muon into an electron in the field of
a aluminum nucleus. The dynamics of such a process is well
modelled by a two-body decay, resulting in a mono-energetic electron with
an energy slightly below the muon rest mass (104.967 MeV).
If no events are observed in three...

In the upcoming **J**uelich **E**lectric **D**ipole moment **I**nvestigations (**JEDI**) project, the essential point will be to measure a tiny beam polarization change over an extended period of time. The particle scarcity in the polarised deuteron or proton beams and its slow extraction rate puts tough experimental limitations on the polarimetry. For the
future EDM measurements, a dedicated...

The (**JEDI**) **J**ülich **E**lectric **D**ipole moment **I**nvestigations collaboration aims to measure tiny polarization changes over a long period of time (see talk by I. Keshelashvili). In the following presentation, the results of beam tests of the new developed LYSO modules for the future polarimeter will be presented. For the tests, four detector modules have been built. The first...

The high luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN is expected to provide instantaneous luminosities of 5 × 10^34 cm−2 s−1. The high luminosities expected at the HL-LHC will be accompanied by a factor of 5 to 10 more pileup compared with LHC conditions in 2015, causing general confusion for particle identification and event reconstruction. Precision timing allows to...

At the HL-LHC, more than 140 concurrent pp interactions, will deteriotate the energy resolution and identificatification capabilities of calorimeters. The possibility to distinguish neutral particles coming from different interaction vertices is being pursued as a tool to reduce pile-up contamination in calorimeters, and restore optimal performance. A time of flight resolution of the order of...

At present new SuperKEKB collider is under commissioning at KEK (Japan) while the Belle II detector for experiments at this collider is at the final stage of the construction. This new experiment will continue and widen the studies began at the previous experiments with the Belle detector. The luminosity of this collider will exceed the previous one by about 40 times, amounting to $8\times...

In this report we outline the study of the development of calorimeter detectors using bright scintillating crystals. We discuss how timing information with a precision of a few tens of pico seconds and below can significantly improve the reconstruction of the physics events under challenging high pileup conditions to be faced at the High-Luminosity LHC or a future hadron collider. The...

The electromagnetic calorimeter (EMC) of the PANDA detector at the future FAIR facility comprises more than 15,000 lead tungstate (PWO) crystals. The barrel part will consist of 11 crystal geometries with different degree of tapering, which causes a non-uniformity in light collection as an interplay between the focusing and the internal absorption of the light. For the most tapered crystals...
