Synchrotron Radiation Reflections in the CLIC Beam Delivery System / Arominski, Dominik (Warsaw University of Technology (PL)) ; Latina, Andrea (CERN) ; Sailer, Andre (CERN) ; Schulte, Daniel (CERN)
Synchrotron radiation (SR) reflection is an important issue for future linear colliders. High fluxes of SR might impact the performance of the detector, through irradiation of the forward luminosity and beam quality calorimeters or of the innermost layers of the vertex detector. [...]

Resistive Wall Effects in the CLIC Beam Delivery System / Arominski, Dominik (Warsaw University of Technology (PL)) ; Latina, Andrea (CERN) ; Schulte, Daniel (CERN)
Resistive wall wakefields are an important issue to study for future linear colliders. Wake- fields in the Beam Delivery System (BDS) might cause severe multi-bunch effects, leading to beam quality and luminosity losses. [...]

(Santiago de Compostela U.) et al.
The kinematics of two-neutron emission following the $\beta$-decay of $^{11}$Li was investigated for the first time by detecting the two neutrons in coincidence and by measuring their angle and energy. [...]
