“…APC128 contains 128 channels, each channel consisting of a low-noise integrator at the input and 32 analogue memory cells (figure 2). The DIMEX detector was used in a series of unique experiments that resulted in new data about the dynamics of structural evolution of several materials after shock loads [8][9][10][11][12]. At the same time the limitation of frame length at the level of 500 ns mainly due to a slow input integrator which has signal settling time of 70-80 ns as well as slow reset switch of the integrator, does not allow to get more detailed information, that has principal importance in some cases.…”

A: A specialized integrated circuit was developed for the readout of signal from coordinate detectors of different types, including gas micro-pattern detectors and silicon microstrip detectors. The ASIC includes 64 channels, each containing a low-noise charge-sensitive amplifier with a connectable feedback capacitor and resistor, and fast reset of the feedback capacitor. Each channel of the ASIC also contains 100 cells of analogue memory where the signal can be stored at a rate of 10 MHz. The pitch of input pads is 50 µm and the chip size is 5 × 5 mm 2 . The equivalent noise charge of the ASIC channel is about 2000 electrons with 10 pF capacitance at the input and maximal signal before saturation corresponds to 2 × 10 6 electrons. The first application for this ASIC is the detector for imaging of explosions at a synchrotron radiation beam (DIMEX), where it has to substitute the old and slower APC128 ASIC. The full-size electronics including 8 ASICs for 512 channels was assembled and tested.
