This modular designed scintillation detector is capable to determine particle's position two-dimensional with resolution of a few mm for minimum ionizing particles. POSSUMUS is usable for large area trigger applications with few readout channels. The idea of this detector is to combine two trapezoidal shaped plastic scintillators to form one rectangular shaped scintillator rod. Each trapezoid in a rod is optically insulated against the other. In both trapezoids the scintillation light is collected by wavelength shifting fibers (WLS-fibers) and guided to Silicon-Photo-Multipliers (SiPM), where the light yield is detected. The SiPMs are located at opposite sites of each WLS-fiber, an automatic voltage adjustment allows for a stable gain of the detected light signals. Position resolution in the transverse direction is achieved by the geometric shape of the scintillators. The amount of light produced by incoming particles is proportional to their path length in the trapezoid and thus position dependent. The longitudinal position resolution, along the scintillator rod, is determined by the propagation time of light to either end of the rod. Because of its modularity, the POSSUMUS-detector can be used for trigger applications of different sizes with only few readout channels. By combining several scintillator rods, position sensitive areas from 100 cm2 to few m2 are achievable. In this talk we present a fully operating prototype of POSSUMUS, the multi-channel gain stabilization system for SiPMs and results for transverse and longitudinal position resolution Summary Primary Authors: RUSCHKE, Alexander (Ludwig-Maximilians-Univ.

To evaluate the influence of different active media and different absorbers, dedicated experiments with tungsten and steel hadron calorimeters of the CALICE collaboration have been carried out. These use plastic scintillator tiles with SiPM readout and RPCs, both arranged as 15 small detector cells read out with fast digitizers and deep buffers. The results of the studies provide detailed information on the time structure of hadronic showers, and are confronted with GEANT4 simulations to evaluate the realism of current hadronic shower models with respect to the time evolution of hadronic cascades.

This experiment aims to study the KL->pi0nunubar decay with an electromagnetic calorimeter and hermetic veto detectors placed around a neutral with high neutron and kaon rates. The veto system requires a gamma-ray detector which should be located in the beam and able to detect gammas escaping there with high efficiency even under the large neutron flux of 500MHz. This detector consists of multiple modules of lead and aerogel pair. Incident gammas are converted to electrons and positrons in lead sheets and photons from their Cerenkov radiation in aerogel are viewed by photomultiplier tubes. Since protons or charged pions, which are mainly produced by neutrons, do not emit Cerenkov lights because of their small velocity, excellent blindness to neutrons can be achieved while keeping high photon detection efficiency around 99.9% for energy larger than 1 GeV. The half number of modules of the detector were installed and actually worked as an in-beam photon veto detector in the first physics data taking of the KOTO experiment. The detector operated stably during 1 week of data taking and expected performance on gamma-ray detection was confirmed as a result of evaluation using KL->3pi0 decay events. In this presentation, the design of this detector, stability and performance studies in the physics data taking, and the future prospects will be reported.

To keep triggering with a similar performance as in Run 1, the CMS muon trigger is currently being upgraded. The new algorithms will provide higher resolution, especially for the muon transverse momentum and will make use of isolation criteria that combine calorimeter with muon information already in the level-1 trigger. The demands of the new algorithms can only be met by upgrading the level-1 trigger system to new powerful FPGAs with high bandwidth I/O. The processing boards will be based on the new microTCA standard. We report on the planned algorithms for the upgraded Global Muon Trigger (GMT) which combines information from the muon trigger sub-systems and assigns the isolation variable. The upgraded GMT will be implemented using a Master Processor 7 card, built by Imperial College, that features a large Xilinx Virtex 7 FPGA. Up to 72 optical links at 10 Gb/s will be used to receive energy sums from the calorimeter trigger and muon candidates directly from the sector processors of the upgraded trigger, absorbing the final sorting stage of each muon sub-system and thus minimizing the latency of the trigger.

The PANDA detector at the future FAIR facility at GSI will use a Barrel-DIRC for the central region and a Disc-DIRC for the forward angular region between 5 and 22 degrees. It will be the first time, that a Disc-DIRC is used in a high performance 4π detector. To achieve this aim different designs and technologies have been evaluated. So far two prototypes have been built and were successfully tested during beam times at DESY and CERN. Their results will be presented. An overview of the technical challenges and the evolution of various design options of the PANDA Disc DIRC detector is given and the capabilities of this novel detector concept will be highlighted.

The combination of dense, new scintillator materials with compact photon detector solutions insensitive to magnetic fields provides a promising prospect to meet the requirements in modern combined molecular imaging modalities. The energy response and temperature dependence of both, the scintillator and photon sensor has been studied for two scintillator materials, Pr:LuAG and Ce:GAGG coupled to either a n-on-p or p-on-n type SiPM. The performance was compared to a CsI crystal coupled to a conventional small vacuum based photon sensor. Summary We studied new combinations of inorganic scintillators and SiPM in comparison to more established technologies to evaluate their suitability for nuclear imaging modalities in medicine.

The calibration system on the first prototype of the AHCAL in CALICE used one optical fibre for each of 7608 channels to distribute calibration light to tiles with SiPM. As the proposed analogue hadronic calorimeter for ILC should have around 10^6 channels, the former system is inapplicable due to spatial requirements and manufacture difficulties. Now two ways of light distribution are considered. The first one is focused on the implementation of one LED placed directly on PCB for each SiPM channel. The second one is focused on a simplified fibre distribution system using one fibre with taps for more channels. It uses so called notched fibre and will be presented here. The system allows to calibrate one row of 72 scintillation tiles read by SiPMs using one driver with one LED and three subsequent notched fibres. We will present principals, parameters of current system and requirements for future development to allow reliable manufacturing. Benefits and drawbacks of notched fibre system with a comparison to the system with embedded LED for each SiPM channel is also discussed. Further we report on latest version of the electronics for calibration and monitoring system developed for single UV-LED. The system is based on original fast (3 ns pulsewidth) and precise LED driver called QMB. Due to its high dynamic range of precise a few nanosecond pulses it is flexible to all necessary monitoring and calibration task for SiPM like detectors.

Highly granular calorimeters will play an important part in achieving this high precision as they allow the application of Particle Flow Algorithms. These calorimeters are being developed by the CALICE collaboration and several prototypes have already been build and tested. The optimization of PFA is supported best if hadronic interactions are well modeled in Monte Carlo simulations. The development and improvement of such hadronic shower models relies on detailed reference data which these prototypes can provide. We have studied interactions of negatively charged pions in the highly granular CALICE silicon-tungsten electromagnetic calorimeter (Si-W ECAL) prototype in the energy range of 2 to 10 GeV and compared various global hadronic shower observables to different Monte Carlo models in the simulation toolkit Geant4. The Si-W ECAL is very sensitive to the start of the hadronic shower and we have developed an algorithm optimised to ﬁnd interactions at small hadron energies and can identify the interaction point with an accuracy of ± 2 layers at an eﬃciency of at least 50% at 2 GeV and at least 80% at 10 GeV. The efficient detection of the shower starting point and shape will improve the performance of Particle Flow Algorithms. The algorithms aim to reconstruct each particle in the optimal subdetector and therefore gain in performance with an improved shower recognition and separation. We are applying advanced machine learning algorithms to improve the detection and separation efficiency.

The requirements for the reactor monitor are to be nonflammable and nonvolatile. As such a detector, we are developping a water-based liquid scintillator. One of the problems of a water-based scintillator is that it is difficult to get enough light yield bucause most of the known luminescent agents are difficult to dissolve in water. We tried to dissolve a liminescent agent in water with sevarel surfactants and measured the light yield varying concentrations of the liminescent agent and surfactants. The scintillators are contained in a vial (4cm diameter and 6cm height) and the light yield is measured using compton edge electrons by gamma-rays from a cobalt 60. We used a blue LED for light yield calibration. As one of the results, we got about 30 photo-electrons for a scintillator consisting of water, PPO (luminescent agent), Bis-MSB (wavelength shifter), and sodium dodecylsulfate (surfactant). Neutrino interactions are identified by a well-known coincidence of a prompt positron signal followed by a delayed neutron capture by gadlinium. In addition to the light yield measurement described previously, we will report about development of the gadlinium-loaded water-based liquid scintillator.
