7. Active target with MPPC readout
Characteristics
Fast time response
Work in a high beam intensity
Large gain (105106)
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.
