structure; the hadronic calorimeter (HCAL) has 60 steel absorber plates with scintillating material inserted in between. These inner CLICdet layers are enclosed in a superconducting solenoid magnet with a field strength of 4 T. This magnetic field bends charged particles, allowing for momentum and charge measurements. The magnet is then surrounded by an iron yoke which would contain large area detectors for muon identification. The detector also has a luminosity calorimeter (LumiCal) to measure the products of Bhabha scattering events, a beam calorimeter to complete the ECAL coverage down to 10 mrads polar angle, and an intra-train feedback system to counteract luminosity loss due to relative beam-beam offsets. Power pulsing and cooling Strict requirements on the material budget for the vertex and tracking system do not allow the use of conventional liquid cooling systems for CLICdet. Therefore, it is proposed that a dry gas cooling system will be used for this inner region. Air gaps have been factored into the design of the detector to allow the flow of the gas, which will be air or Nitrogen. To allow for effective air cooling, the average power consumption of the Silicon sensors in the vertex detector needs to be lowered. Therefore, these sensors will operate via a current-based power pulsing scheme: switching the sensors from a high to low power consumption state whenever possible, corresponding to the 50 Hz bunch train crossing rate. Status , approximately two percent of the CERN annual budget is invested in the development of CLIC technologies. The first stage of CLIC with a length of around is currently estimated at a cost of six billion CHF. CLIC is a global project involving more than 70 institutes in more than 30 countries. It consists of two collaborations: the CLIC detector and physics collaboration (CLICdp), and the CLIC accelerator study. CLIC is currently in the development stage, conducting performance studies for accelerator parts and systems, detector technology and optimisation studies, and physics analysis. In parallel, the collaborations are working with the theory community to evaluate the physics potential of CLIC. The CLIC project has submitted two concise documents as input to the next update of the European Strategy for Particle Physics (ESPP) summarising the physics potential of CLIC as well as the status of the CLIC accelerator and detector projects. The update of the ESPP is a community-wide process, which is expected to conclude in May 2020 with
