In experiments with radioactive beams from heavy ions facilities it is shown that active targets and TPCs experimental methods are effective means to study nuclear spectroscopy. The principle advantages are good resolution, versatility and high luminosity. To address the needs of the nuclear Physics community we are in the process of developing a Generic Electronic system for TPCs (GET) to cover small to medium sized instrumentation (64 to 32k channels)with a relatively wide charge dynamic ranges. The front-end electronics AsAd(ASIC Support & Analog-Digital conversion) sample input signals and transmits data to processing modules.

Summary 500 words

AsAd system architecture includes 4 x 64Channels input ASIC (AGET) having individual adjustable polarity, gains, shaping, discriminator and pulser input. The pre-amp and filter can be either internal or external. Input signals are continuously sampled (100MHz) and read on 4 x 12 bit ADC (25MHz). The ADC also codes the multiplicity time sequence. A 64 channel register per AGET is read and allows a selective computed read-out window of the SCA. The front-end board is monitored by a FPGA. Its includes a built-in power supply with continuous monitoring, a calibration pulser and a set of synchronization and inspections lines.
