We report on the light sterile neutrino search from the first four-week science run of the KATRIN experiment in~2019. Beta-decay electrons from a high-purity gaseous molecular tritium source are ...analyzed by a high-resolution MAC-E filter down to 40 eV below the endpoint at 18.57 keV. We consider the framework with three active neutrinos and one sterile neutrino of mass \(m_{4}\). The analysis is sensitive to a fourth mass state \(m^2_{4} \lesssim\) 1000 eV\(^2\) and to active-to-sterile neutrino mixing down to \(|U_{e4}|^2 \gtrsim 2\cdot10^{-2}\). No significant spectral distortion is observed and exclusion bounds on the sterile mass and mixing are reported. These new limits supersede the Mainz results and improve the Troitsk bound for \(m^2_{4} <\) 30 eV\(^2\). The reactor and gallium anomalies are constrained for \( 100 < \Delta{m}^2_{41} < 1000\) eV\(^2\).
The ALICE Central Trigger Processor (CTP) is going to be upgraded for LHC Run 3 with completely new hardware and a new Trigger and Timing Control (TTC-PON) system based on a Passive Optical Network ...(PON) system. The new trigger system has been designed as dead time free and able to transmit trigger data at 9.6 Gbps. A new universal trigger board has been designed, where by changing the FMC card, it can function as a CTP or as a LTU. It is based on the Xilinx Kintex Ultrascale FPGA and upgraded TTC-PON. The new trigger system and the prototype of the trigger board will be presented.
