A Medium Sized Telescope prototype for the Cherenkov Telescope Array — •Louise Oakes — Humboldt Universität zu Berlin, Berlin, Deutschland

The CTA (Cherenkov Telescope Array) is a proposed next generation instrument to observe very high energy (VHE) gamma-rays at ground level. The array will consist of 3 sizes of telescope covering a wide photon energy range: small (4m diameter) telescopes sensitive to the highest energy photons, medium sized telescopes (12m) operating in the mid energy range, and a small number of large telescopes ( 24m) with high sensitivity to low energy photons. Current Cherenkov Telescope experiments consist of up to 5 telescopes; CTA will be made up of an order of magnitude more, which will greatly enhance the number of photons that can be detected as well as increasing the number of views of each cascade, bringing significantly improved angular resolution and background suppression. The observatory is currently in the planning and development phase. A prototype CTA medium sized telescope (MST) is being built in Adlershof (Berlin). This talk will focus on plans for CTA and the design and construction of the MST prototype, as well as its operation, instrumentation and early measurement results.
