Based on a paper published in 2019 by the FCAL Collaboration, this talk is giving an update of the Collaborations effort to design prototype of highly compact calorimeter to instrument the very forward region of a detector at future $e^+e^-$ colliders. A luminometer prototype, based on sub-millimeter thick detector planes, is tested with an electron-beam of energy 1-5 GeV. The effective Moliere radius of the prototype comprising eight detector planes was measured to be (8.1 +/- 0.1 (stat.) +/- 0.3 (syst.))mm, and the result is well reproduced by the Monte Carlo simulation.

This note describes R&D to be carried out on the data acquisition system for a calorimeter at the future International Linear Collider. A generic calorimeter and data acquisition system is described. Within this framework modified designs and potenti
al bottlenecks within the current system are described. Solutions leading up to a technical design report will to be carried out within CALICE-UK groups.
The FCAL collaboration is preparing large-scale prototypes of special calorimeters to be used in the very forward region at future electron-positron colliders for a precise measurement of integrated luminosity and for instant luminosity measurement a
nd assisting beam-tuning. LumiCal is designed as a silicon-tungsten sandwich calorimeter with very thin sensor planes to keep the Moli`ere radius small, facilitating such the measurement of electron showers in the presence of background. Dedicated front-end electronics has been developed to match the timing and dynamic range requirements. A partially instrumented prototype was investigated in a 1 to 5 GeV electron beam at the DESY II synchrotron. In the recent beam tests, a multi-plane compact prototype was equipped with thin detector planes fully assembled with readout electronics and installed in 1 mm gaps between tungsten plates of one radiation length thickness. High statistics data were used to perform sensor alignment, and to measure the longitudinal and transversal shower development in the sandwich. This talk covers the latest status of the calorimeter prototype development and selected performance results, obtained in test beam measurements, the prospects for the upcoming DESY test beam, as well as the expected simulation performance.
An iron- plastic-scintillator shashlik calorimeter with a 4.3 $X_0$ longitudinal segmentation was tested in November 2016 at the CERN East Area facility with charged particles up to 5 GeV. The performance of this detector in terms of electron energy
resolution, linearity, response to muons and hadron showers are presented in this paper and compared with simulation. Such a fine-grained longitudinal segmentation is achieved using a very compact light readout system developed by the SCENTT and ENUBET Collaborations, which is based on fiber-SiPM coupling boards embedded in the bulk of the detector. We demonstrate that this system fulfills the requirements for neutrino physics applications and discuss performance and additional improvements.
A compact, remote controlled, cost efficient diagnostic station has been developed to measure the charge, the profile and the emittance for low energy proton beams. It has been installed and tested in the proton beam line of the Project Prometheus at SANAEM of the Turkish Atomic Energy Authority.
The Multi-Purpose Detector (MPD) is designed to study a hot and dense baryonic matter formed in heavy-ion collisions at SQRT(sNN)=4-11 GeV at the NICA accelerator complex (Dubna, Russia). Large-sized electromagnetic calorimeter (ECal) of the MPD spec
trometer will provide precise spatial and energy measurements for photons and electrons in the central pseudorapidity region of |eta|<1.2. The Shashlyk-type sampling structure of the ECal is optimized for the photons energy range from about 40 MeV to 2-3 GeV. Fine segmentation and projective geometry of the calorimeter allow to deal with high multiplicity of secondary particles from Au-Au reactions. In this talk, we report on a design, a construction status and expected parameters of the ECal.
