In the present ILC design the beam crossing angle for e+e- collisions is 14 mrad. The photon collider needs the angle about 25 mrad due to larger beam disruption angle. The solution is suggested which decreases the required crossing angle for the photon collider down to 20 mrad and allows to work in both modes of collisions without any degradation of performance.

Future high rate hadron colliders are expected to have hundreds of concurrent proton-proton interactions in the same bunch crossing, deteriorating the reconstruction of the hard scattering event and the identification of calorimeters. The possibility to distinguish neutral particles coming from different interaction vertices is being pursued as a tool to reduce pile-up contamination in...

To accommodate high-luminosity LHC operation at 13 TeV collision energy, the CMS Endcap Muon Level-1 Trigger system had to be significantly modified. To provide the best track reconstruction, the trigger system must now import all available trigger primitives generated by Cathode Strip Chambers and by certain other subsystems, such as Resistive Plate Chambers (RPC). In addition to massive...

We built an adaptive power supply that used a linear...
