  An energy-frontier or QCD-exploring ep and gp collider can be realized by colliding high-energy photons generated by Compton back-scattered off a CLIC electron beam, at either 75 GeV or 1.5 TeV, with protons or ions stored in the LHC. In this study we discuss a performance optimization of this type of collider by tailoring the parameters of both CLIC and LHC. An estimate of the ultimately achievable luminosity is given.

  We explore the possibility of laser-based postlinac beam collimation in future linear colliders. A laser employed as a spoiler can neither be 'destroyed' by the beam impact and nor generate collimator wake fields. In addition, the postlinac collimation section, presently the longest part of linear-collider beam delivery systems, can be shortened. In this paper, we investigate different types of laser modes for use as spoiler. Suitable laser beam parameters and modes are discussed for collimation in both CLIC and ILC.

  The CLIC study is high power testing accelerating structures in a number of different materials and accelerating structure designs to understand the physics of breakdown, determine the appropriate scaling of performance and in particular to find ways to increase achievable accelerating gradient. The most recent 30 GHz structures which have been tested include damped structures in copper, molybdenum, titanium and aluminum. The results from these new structures are presented and compared to previous ones to determine dependencies of quantities such as achievable accelerating gradient, pulse length, power flow, conditioning rate and breakdown rate.
