“…Shashlik calorimeters [1,2] are sampling calorimeters in which the scintillation light is readout by wavelength shifting (WLS) fibers running perpendicularly to the absorber and converter plates. Shashlik devices are used since more than 20 years in particle physics [4][5][6][7][8] but the recent developments in the technology of silicon-based photosensors provide new solutions for light collection and readout [9][10][11][12][13][14] and open a broader range of applications for shashlik detectors [15,16]. The most critical limitation of these calorimeters is due to longitudinal segmentation.…”

A: 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.

“…Electromagnetic calorimeter of "Shashlyk" type with optimal configuration on the base of injection molding scintillator was designed at IHEP in the early 2000s and tested jointly with INR RAS group is shown in Figs. 4 and 5 [17][18][19][20]. After that, "Shashlyk"began to be widely used [21][22][23].…”

Abstract:The new designed at Institute for High Energy Physics (IHEP) technologies of polystyrene scintillators manufacturing, molding of polystyrene granules under pressure, melting of granules in forms with mirrors walls, production of scintillating granules and detectors on their basis are considered. The main characteristics of the polystyrene scintillators produced by a method of large-block polymerization and a method of extruding of scintillation strips from polymerized blocks are provided in this article also.

“…We are investigating the possibility of replacing the LKr with a shashlyk-based MEC patterned on the PANDA FS calorimeter (in turn, based on the KOPIO calorimeter [18]), with 110 × 110 mm modules, lead absorber thickness of 0.275 mm, and scintillator thickness of 1.5 mm, read out by silicon photomultipliers via 1-mm diameter WLS fibers. Stochastic energy and time resolutions of better than σ E /E = 2%/ √ E and σ t = 72 ps/ √ E were obtained with this design in KOPIO tests.…”

Precise measurements of the branching ratios for the flavor-changing neutral current decays K → πνν can provide unique constraints on CKM unitarity and, potentially, evidence for new physics. It is important to measure both decay modes, K + → π + νν and KL → π 0 νν, since different new physics models affect the rates for each channel differently. The NA62 experiment at the CERN SPS will measure the BR for the charged channel to better than 20%. The BR for the neutral channel has never been measured. We are designing the KLEVER experiment to measure BR(KL → π 0 νν) to ∼20% using a high-energy neutral beam at the CERN SPS. The boost from the high-energy beam facilitates the rejection of background channels such as KL → π 0 π 0 by detection of the additional photons in the final state. On the other hand, the layout poses particular challenges for the design of the smallangle vetoes, which must reject photons from KL decays escaping through the beam exit amid an intense background from soft photons and neutrons in the beam. We present findings from our design studies, with an emphasis on the challenges faced and the potential sensitivity for the measurement of BR(KL → π 0 νν).
