Description
The ISIS (In-Situ charge storage Imaging Sensor) is a monolithic active pixel sensor with memory cells in each pixel. The memory cells are implemented as a CCD register. The device is a "burst camera" with charge being clocked simultaneously into the registers in each pixel. This makes the ISIS an excellent sensor for the ILC vertex detector for various reasons. The sensors can be made very thin while still retaining a high S/N ratio. The charge liberated by the passage of a particle is stored in potential wells inside the pixel and not amplified and sampled except outside the bunch-train, making the device less sensitive to EMI. The ISIS1 is a proof-of-principle ISIS device. In October 2007 we performed tests at the DESY e- beam-line with a telescope consisting of 5 ISIS1 sensors. The first test-beam results including S/N and position resolution will be shown.
