Active target with MPPC readout Characteristics Fast time response Work in a high beam intensity Large gain (105106) Possible to detect 1 photon Operation in the magnetic field Combination of Imaging and Spectrometer Trigger possibility Now we are developing a Scifi active target using MPPC readout. MPPC has the following characteristics. Fast time response, so it can work in a high beam intensity. Large gain, it is possible to detect MIP signal MPPC can operate in a magnetic field, we can combine the imaging and spectrometer Like this figure. Active target is surrounded by tracking chamber and outgoing particles from target Can be detected by the spectrometer. It can make a trigger to select scattering event.
