Abstract This paper describes MUSTANG 2, a 338 element focal plane array that is being built for the Green Bank Telescope. Each element consists of a profiled feedhorn coupled to two transition edge sensor bolometers, one for each polarization. Initial deployment will be with 32 detectors, but once fully populated, MUSTANG 2 will be capable of mapping a %$8'\times 8'%$ area to %$23~\mu %$Jy in 1 h with good image fidelity on angular scales from %$9''%$ to %$6'%$. As well as an instrument overview, the choice of bandpass and the design of the feeds, detectors and readout are given. Ausführliche Beschreibung
