Charge calibration of MALTA2, a radiation hard depleted monolithic active pixel sensor
MALTA2 is a depleted monolithic active pixel sensor (DMAPS) designed for tracking at high rates and typically low detection threshold of $\sim150\,\mathrm{e^-}$. A precise knowledge of the threshold is crucial to understanding the charge collection in the pixel and specifying the environment for sen...

| description | MALTA2 is a depleted monolithic active pixel sensor (DMAPS) designed for
tracking at high rates and typically low detection threshold of
$\sim150\,\mathrm{e^-}$. A precise knowledge of the threshold is crucial to
understanding the charge collection in the pixel and specifying the environment
for sensor application. A simple procedure is developed to calibrate the
threshold to unit electrons making use of a dedicated charge injection circuit
and an Fe-55 source with dominant charge deposition of $1600\, \mathrm{e^-}$.
The injection voltage is determined which corresponds to the injection under
Fe-55 exposure and is the basis for charge calibration. The charge injection
circuit incorporates a capacitance with design value of $\mathrm{C_{inj}}=$ 230
aF. Experimentally, the average capacitance value for non-irradiated samples is
found to be $\mathrm{C_{inj,exp}}=$ 257 aF. The 12 % divergence motivates the
need for the presented precise calibration procedure, which is proposed to be
performed for each MALTA2 sensor. |
