Query: Inauguration and First Light of the GCT-M Prototype for the Cherenkov
  Telescope Array   The Gamma-ray Cherenkov Telescope (GCT) is a candidate for the Small Size
Telescopes (SSTs) of the Cherenkov Telescope Array (CTA). Its purpose is to
extend the sensitivity of CTA to gamma-ray energies reaching 300 TeV. Its
dual-mirror optical design and curved focal plane enables the use of a compact
camera of 0.4 m diameter, while achieving a field of view of above 8 degrees.
Through the use of the digitising TARGET ASICs, the Cherenkov flash is sampled
once per nanosecond continuously and then digitised when triggering conditions
are met within the analogue outputs of the photosensors. Entire waveforms
(typically covering 96 ns) for all 2048 pixels are then stored for analysis,
allowing for a broad spectrum of investigations to be performed on the data.
Two prototypes of the GCT camera are under development, with differing
photosensors: Multi-Anode Photomultipliers (MAPMs) and Silicon Photomultipliers
(SiPMs). During November 2015, the GCT MAPM (GCT-M) prototype camera was
integrated onto the GCT structure at the Observatoire de Paris-Meudon, where it
observed the first Cherenkov light detected by a prototype instrument for CTA.
