Abstract / Description:Abstract—For the detection of secondary vertices of long lived
particles containing bottom and charm quarks at the International
Linear Collider (ILC), a DEPFET pixel detector is one of the technologically
favored options. In a DEPFET sensor a MOSFET pixel
detector is integrated on a sidewards depleted silicon bulk sensor,
thus combining the advantages of a fully depleted silicon sensor
with in-pixel amplification. DEPFET pixel matrices have been
characterized in a high energy particle beam. Since the DEPFET
is a very high precision device, given its large S N ( 100) and
small pixel size (36 22 m2), a DEPFET based pixel telescope
consisting of 5 DEPFETs has been developed. The uncertainty on
the predicted position for a device under test (DUT) positioned
inside the telescope was found to be 1.4 m with the existing
device, due to the limited performance of two of the five DEPFET
planes. A DEPFET telescope built of 5 modules equivalent to the
best plane presented here, would have a track extrapolation error
as low as 0.65 m at the DUT plane.
